AB  - Kopriva (Urtica dioica) je samonikla biljka bogata flavonoidima, karotenoidima, fitosterolima,
terpenima. Ima izuzetan farmaceutski potencijal zbog svojih antiinflamatornih, antioksidativnih i
diuretskih svojstava. Koristi se u ishrani, kao caj ili u formi suvih ili tecnih ekstrakta. U cilju
pobiljšanja karakteristika, bioraspoloživosti i stabilnosti ekstrakata, koriste se ekstrakcije ekološki
prihvatljivim rastvaracima, zeleni fizicki tretmani i fermentacija probiotickim bakterijama. Zeleni
rastvaraci kao što su voda, etanol i biokompatibilni eutekticke tecnosti su pogodni za dobijanje
ekstrakata u skladu sa principima održivog razvoja. Inovativni fizicki tretmani kao netermalni
tretman plazmom mogu obezbediti bolju ekstrakciju i mikrobiološku stabilnost posebno vodenih
ekstrakata. Takode, fermentacije bakterijama, kao što je Ligilactobacillus salivarius, mogu da
metabolišu jedinjenja prisutna u ekstraktima i biotransformišu glikozide, tanine i lignane u biološki
aktivnije oblike.
U radu smo ispitivali rast i antioksidativnu aktivnost vodenih ekstrakata cveta koprive dobijenih uz
tretman netermalnom plazmom i potom fermentaciju sa L. salivarius. Ispitali smo rast L. salivarius
u medijumima sa razlicitim udelom vodenog ekstrata cveta koprive i Man Rogosa Šarp (MRS) bujona
koji je koristi kao standardni mikrobiološki medijum za kultivaciju bakterija mlecne kiseline.
Antioksidativna aktivnost dobijenih ekstrakata je ispitana DPPH metodom, pre i nakon fermentacije.
L. salivarius je pokazao najbolji rast (11 log CFU/ml) u ekstraktima obogacenim sa 25% MRS. Potom
je je ispitivan rast L. salivarius u plazma tretiranom vodenom ekstraktu koprive sa 25% MRS. Nakon
tretmana netermalnom plazmom od 3 min i naknadne fermentacije ovih ekstrakata, postignut je rast
od 9 log CFU/ml i porast antioksidativne aktivnosti od 27% DPPH metodom. Uocen je pozitivan
kombinovani efekat netermalne plazme i fermentacije na povecanje antioksidativne aktivnosti,
posebno pri kracim tretmanima netermalnom plazmom. Rezultati rada ukazuju na mogucnost
primene zelenih tretmana i fermentacije za dobijanje proizvoda ekstrakta cveta koprive obogacenih
sa L. salivarius. Plazma tretman može uticati i na mikrobiološki sastav vodenih ekstrakata, kao
važnog aspekta za primenu u prehrambenoj i farmaceutskoj industriji.

AB  - The last decade provided significant advances in the understanding of microbiota and its role in human health. Probiotics are live microorganisms with proven benefits for the host and were mostly studied in the context of gut health, but they can also confer significant benefits for oral health, mainly in the treatment of gingivitis. Postbiotics are cell-free extracts and metabolites of microorganisms which can provide additional preventive and therapeutic value for human health. This opens opportunities for new preventive or therapeutic formulations for oral administration. The microorganisms that colonize the oral cavity, their role in oral health and disease, as well as the probiotics and postbiotics which could have beneficial effects in this complex environment were discussed. The aim of this study was to review, analyse and discuss novel probiotic and postbiotic formulations intended for oral administration that could be of great preventive and therapeutic importance. A special attention has been put on the formulation of the pharmaceutical dosage forms that are expected to provide new benefits for the patients and technological advantages relevant for industry. An adequate dosage form could significantly enhance the efficiency of these products.

AB  - Traditional extraction methods involve the use of polar solvents and/or high temperatures. Both are often energy or time-consuming and require additional purification steps. This compromises the quality of the extracts obtained. Non-thermal plasma pre-treatment for extraction is a promising technique that could increase the sustainability of the process while following the principles of hurdle technology. In this work, we investigated the effects of plasma treatment on the aqueous extraction of antioxidant compounds from herbal tea by-products. Stinging nettle, hoary willowherb, and St. John’s Wort extracts were treated with plasma at different time intervals. The extracts obtained were analyzed for their antioxidant capacity and total phenolic content. Their potential use as growth media for Ligilactobacillus sp. was also investigated. Hoary willowherb extracts showed the highest total phenolic content and antiox-idant activity. While plasma treatment slightly decreased the antioxidant capacity of these extracts, it improved microbial growth. In contrast to hoary willowherb, the antioxidant capacity of stinging nettle extracts’ was not affected by plasma treatment. These extracts were also better for bacterial growth. When added to 25% v/v MRS broth, stinging nettle extracts achieved a growth rate similar to that of pure MRS broth (109 CFU/ml), demonstrating their potential for microbial biomass production and food and feed supplemen-tation.

AB  - Biomass captures CO2 from the atmosphere when growing. In the same time, approximately 1,4 Gt of available renewable biomass is annually wasted while cereal straw wastes contribute to that with 66%. Huge portion of residues is still burnt, while it is the source of bioactives, fermentable sugars and only natural aromatic polymer-lignin.
The main obstacle for valorization of biomass is the recalcitrant nature of dominantly present lignocellulose and variability in biomass composition which decreases already modest efficiency of acid/alkaline thermal treatment conventionally used in biorefineries. Conventional treatments have low selectivity, generate inhibitory compounds for enzymes or microorganisms used in biorefineries and have high environmental footprint.
Cold plasma treatment (CPT) can induce modifications of cellulosic and hemicellulosic fraction as well as oxidation and depolymerisation of lignin, but CPT lacks selectivity in complex substrates such as agri-food wastes. We combined CPT with Fenton reagent or hydrogen peroxide for treatment of corn stalks as significant lignocellulose agri-industrial waste in Serbia. Chemical properties of treated samples were analysed by FTIR, while carbohydrate fraction was subjected to enzymatic hydrolysis followed by spectrophotometric analysis. We showed that delignification with CPT can be efficiently combined with other oxidative treatments, including hydrogen peroxide and Fenton reagent, while preserving or even improving the enzymatic hydrolysis of carbohydrate fractions. Different chemical modifications were obtained depending on Fe/hydrogen peroxide ratio or hydrogen peroxide concentration, however, low energy CPT combined with other oxidative treatments significantly improves delignification and carbohydrate accessibility while decreasing overall processing time and energy consumption.
Further studies have to evaluate oxidative treatments and CPT sources with different parameters for recovery of all fractions present in lignocellulose. This is essential for sustainable biorefineries on lignocellulose. CPT here shows some additional benefits related to its sterilization and microbial decontamination effect. CPT is already used for surface “etching” and sterilization of grafts in medicine and slowly enters food industry in the similar application field. It has a prospect to improve biomass decomposition under carefully selected conditions as shown here, but it can also help in control of undesired microbiota in open fermentation processes. This could be very valuable for the number of biorefinery processes and contribute significantly to the bioeconomy.
AB  - Biljna biomasa vezuje CO2 iz atmosphere kada raste. U isto vreme, otprilike 1,4 Gt dostupne obnovljive biomase se
godišnje baca, dok slama žitarica koja se smatra otpadom učestvuje sa oko 66% u toj količini. Veliki deo agroindustrijskog
otpada se i dalje spaljuje, dok je istovremeno izvor bioaktivnih jedinjenja, fermentativnih šećera i jedinog prirodnog
aromatičnog polimera –lignina.
Osnovno ograničenje u valorizaciji biomase predstavlja rezistentnost lignoceluloze, dominantne frakcije u većini
sporednih sirovina agroindustrijskog porekla, kao i varijabilnost sastava. Time se dodatno smanjuje i onako ogranična
efikasnost kiselinskih/baznih termalnih tretmana koji se konvencionalno koriste u biorafinerijskim postupcima.
Konvencionalni tretmani imaju malu selektivnost, u njima nastaju inhibitorni proizvodi za enzime i mikroorganizme koje
se koriste u biorafinerijskim postupcima i imaju značajan uticaj na životnu sredinu.

abstract = "Biomass captures CO2 from the atmosphere when growing. In the same time, approximately 1,4 Gt of available renewable biomass is annually wasted while cereal straw wastes contribute to that with 66%. Huge portion of residues is still burnt, while it is the source of bioactives, fermentable sugars and only natural aromatic polymer-lignin.
The main obstacle for valorization of biomass is the recalcitrant nature of dominantly present lignocellulose and variability in biomass composition which decreases already modest efficiency of acid/alkaline thermal treatment conventionally used in biorefineries. Conventional treatments have low selectivity, generate inhibitory compounds for enzymes or microorganisms used in biorefineries and have high environmental footprint.
Cold plasma treatment (CPT) can induce modifications of cellulosic and hemicellulosic fraction as well as oxidation and depolymerisation of lignin, but CPT lacks selectivity in complex substrates such as agri-food wastes. We combined CPT with Fenton reagent or hydrogen peroxide for treatment of corn stalks as significant lignocellulose agri-industrial waste in Serbia. Chemical properties of treated samples were analysed by FTIR, while carbohydrate fraction was subjected to enzymatic hydrolysis followed by spectrophotometric analysis. We showed that delignification with CPT can be efficiently combined with other oxidative treatments, including hydrogen peroxide and Fenton reagent, while preserving or even improving the enzymatic hydrolysis of carbohydrate fractions. Different chemical modifications were obtained depending on Fe/hydrogen peroxide ratio or hydrogen peroxide concentration, however, low energy CPT combined with other oxidative treatments significantly improves delignification and carbohydrate accessibility while decreasing overall processing time and energy consumption.
Further studies have to evaluate oxidative treatments and CPT sources with different parameters for recovery of all fractions present in lignocellulose. This is essential for sustainable biorefineries on lignocellulose. CPT here shows some additional benefits related to its sterilization and microbial decontamination effect. CPT is already used for surface “etching” and sterilization of grafts in medicine and slowly enters food industry in the similar application field. It has a prospect to improve biomass decomposition under carefully selected conditions as shown here, but it can also help in control of undesired microbiota in open fermentation processes. This could be very valuable for the number of biorefinery processes and contribute significantly to the bioeconomy., Biljna biomasa vezuje CO2 iz atmosphere kada raste. U isto vreme, otprilike 1,4 Gt dostupne obnovljive biomase se
godišnje baca, dok slama žitarica koja se smatra otpadom učestvuje sa oko 66% u toj količini. Veliki deo agroindustrijskog
otpada se i dalje spaljuje, dok je istovremeno izvor bioaktivnih jedinjenja, fermentativnih šećera i jedinog prirodnog
aromatičnog polimera –lignina.
Osnovno ograničenje u valorizaciji biomase predstavlja rezistentnost lignoceluloze, dominantne frakcije u većini
sporednih sirovina agroindustrijskog porekla, kao i varijabilnost sastava. Time se dodatno smanjuje i onako ogranična
efikasnost kiselinskih/baznih termalnih tretmana koji se konvencionalno koriste u biorafinerijskim postupcima.
Konvencionalni tretmani imaju malu selektivnost, u njima nastaju inhibitorni proizvodi za enzime i mikroorganizme koje
se koriste u biorafinerijskim postupcima i imaju značajan uticaj na životnu sredinu.

AB  - During the processing of herbs, a significant amount of chopped biomass by-products is left behind, often discarded and underutilized. Since they are important sources of different groups of bioactives like polyphenolics, essential oils or terpenes and structural compounds like lignocellulose, they could be exploited in fermentation by different microorganisms. However, fractionation and extractions could significantly increase the effectiveness and productivity of the valorization process. We examined the possibility of extracting antioxidants from by-products of hoary willowherb (Epilobium spp.), sage (Salvia spp.), and
basil (Ocimum spp.), as medicinal herbs with significant pharmaceutical and market value. Extracts of hoary willowherb, sage and basil residues were obtained by a conventional, Soxhlet extraction for polar compounds and supercritical carbon(IV)-oxide extraction as an unconventional extraction method for non-polar compounds. We measured the antioxidant content in the obtained extracts by the ABTS and DPPH spectrophotometric methods. In addition, we measured the total polyphenol content of the extracts by the Folin-Coicalteu
method. According to the ABTS method, the antioxidant activity in the sage extracts obtained from Soxhlet extraction is 2.2 times greater than in the extracts obtained from supercritical carbon(IV)-oxide extraction. The antioxidant activity in the basil extracts obtained from Soxhlet extraction is 9.1 times greater than in the extracts obtained from supercritical carbon(IV)-oxide extraction, according to the DPPH method. The total polyphenol content in the hoary willowherb extracts obtained from Soxhlet extraction is 4.6 times greater than in the extracts obtained from supercritical carbon(IV)-oxide extraction. The antioxidant activity is greater in the extracts obtained by Soxhlet extraction than in the extracts obtained with supercritical carbon(IV)-oxide extraction. Because we examined residues from the tea processing industry, the content of easily volatile non-polar components is expected to be lower. The results confirm that valorization of these residues should be focused on the polar components and their microbial biotransformations.

AB  - To provide food with a longer shelf life, synthetic antioxidants are frequently used in the food industry. Common synthetic antioxidants includebutylated hydroxyanisole(BHA), butylated hydroxytoluene (BHT), propyl gallate (PG), and tert-butylated hydroquinone (TBHQ). Since those compounds are suspected to cause some health problems, such as liver damage, there is a strong initiative to develop and utilizeantioxidantsfrom natural origins.Medicinal plants could be a good alternative source of these compounds. Besides antioxidative properties, natural compounds derived from medicinal plants often have various biological activities, like anti-inflammatory, antimicrobial, analgesic, etc.These compounds can contribute to food's functional and technological properties and interact with food microbiota. In this study, aqueous extracts of tea production residues of common nettle (Urtica dioica L.), St. John’s wort (Hypericum perforatum L.), and hoary willowherb(Epilobium parviflorum L.) were treated with non-thermal plasma. The effect of different durations of plasma treatment on the antioxidative capacity of these extracts was monitored. The fermentation of these extracts solely and extracts supplemented with MRS broth by Ligilactobacillus salivarius was examined. Antioxidative properties of plasma-treated extracts were analyzed using DPPH and ABTS methods. The total phenol content of these extracts was determined by the Folin-Ciocalteu reagent. Generally, hoary willowherb extracts were rich in total phenol content, two or three orders of magnitude richer than the other two plants. They also showed significantly higher antioxidative activity. This activity slightly decreased with prolonged plasma treatment. However, that didn’t affect bacterial growth in these extracts. It was shown that L. salivarius growth was enhanced in the pure plasma-activated extracts of hoary willowherbin comparison to extracts supplemented with MRS broth. Though, the observed effects are substrate-dependent and vary from plant to plant. The antioxidative capacity of common nettle extracts remained intact during the plasma treatment. With the addition of MRS broth (25% v/v), bacterial growth was completely unhindered, providing approximately 109 CFU/ml during the exponential phase. Moreover, the 10-minute-long plasma treatment was effective in the inactivation of microorganisms already present in herbal biomass, preventing the spoilage of treated extracts. This could be an important step up in extraction by hurdle technology, especially in the production of symbiotic preparations possessing both antioxidative and probiotic properties.

AB  - Common nettle (Urtica dioica) is widely spread medicinal plant growing in Europe. It is used as food,
herbal tea or extract in dietary supplements. Significant amount of common nettle herb residues
remains during standard herb processing in herbal tea production – due to grounding and fragility of
dried common nettle’s leaf. These residues are currently underexploited and are considered waste, but
could be used for extraction. Dried or liquid extracts of pharmacopoeial-level quality common nettle
are used in iron supplementation, in treatments of rheumatoid diseases, hyperthensia or hyperglycemic
disorders. Green solvents, water and ethanol are preferable for sustainable extractions and food and
health related applications. Additionally, these solvents favour extraction of polar compounds like
glycosides which could be metabolized by microorganisms. Water extracts do not harm
microorganisms and are used as such in fermentation while ethanol have to be removed before
fermentations.
In our work, we studied water extraction of common nettle herb and its residues and tested these

bacteria with probiotic potential. Antioxidant activity (DPPH and ABTS methods) and growth of L.
salivarius and L. rhamnosus were common nettle’s extracts obtained under different conditions. The
extracts obtained from residues showed comparable or even superior antioxidant activity to extracts
obtained from standard herb. Common nettle extracts without carbon or nitrogen supplementation were
poor substrates for the growth of L. salivarius and L. rhamnosus, while supplementation with broth in
low percentages resulted in growth stimulation above control. Findings suggest that common nettle
herb residues could be valorised in food chain avoiding landfill disposal and wasting of this valuable
resource.

mogu koristiti bez tretmana, jer ne utiču negativno na rast mikroorganizama, dok je iz etanolnih

abstract = "Common nettle (Urtica dioica) is widely spread medicinal plant growing in Europe. It is used as food,
herbal tea or extract in dietary supplements. Significant amount of common nettle herb residues
remains during standard herb processing in herbal tea production – due to grounding and fragility of
dried common nettle’s leaf. These residues are currently underexploited and are considered waste, but
could be used for extraction. Dried or liquid extracts of pharmacopoeial-level quality common nettle
are used in iron supplementation, in treatments of rheumatoid diseases, hyperthensia or hyperglycemic
disorders. Green solvents, water and ethanol are preferable for sustainable extractions and food and
health related applications. Additionally, these solvents favour extraction of polar compounds like
glycosides which could be metabolized by microorganisms. Water extracts do not harm
microorganisms and are used as such in fermentation while ethanol have to be removed before
fermentations.
In our work, we studied water extraction of common nettle herb and its residues and tested these
extracts as substrates for the growth of Ligilactobacillus salivarius and Lacticaseibacillus rhamnosus,
bacteria with probiotic potential. Antioxidant activity (DPPH and ABTS methods) and growth of L.
salivarius and L. rhamnosus were common nettle’s extracts obtained under different conditions. The
extracts obtained from residues showed comparable or even superior antioxidant activity to extracts
obtained from standard herb. Common nettle extracts without carbon or nitrogen supplementation were
poor substrates for the growth of L. salivarius and L. rhamnosus, while supplementation with broth in
