Lignocellulosic biomass is a cheap raw material that, thanks to its high carbohydrate content, can be used in fermentation to
produce biofuels, biogas and other compounds. Its complex structure, including cellulose, hemicellulose and lignin, requires prior
treatment of the biomass to facilitate hydrolysis to simple sugars. Today, biomass is only partially utilized and generates about 14%
of the world´s energy. This is because the most commonly used physical, chemical and physicochemical treatments are not
sustainable. They are energy-consuming but still low in productivity and toxic inhibitors formed during these treatments could hinder
later steps of fermentation.Biomass treatment with advanced oxidation techniques has great potential as an environmentally friendly,
so-called "green" treatment. These processes generate reactive species (radicals, electrons, ions and peroxides) that attack cellulose,
hemicellulose, and lignin components. In this work, the effects of non-thermal ...plasma, the Fenton process, and the combined
treatment of corn stalks with non-thermal plasma/Fenton were compared. Grounded biomass of corn stalks was mixed with Fenton
reagent and hydrogen peroxide at different ratios and subjected to non-thermal plasma treatment. Carbohydrate content was
decreased in non-thermal plasma treated samples both with and without Fe2+. However, a specific biomass: Fe2+:H2O2 ratio was
required to achieve the highest rate of lignocellulose decomposition. The cellulose and hemicellulose fractions were affected and
reduced by the treatments studied but resulted in almost no changes in the cellulose crystallinity index. The lower lignin content and
cellulose crystallinity allow for more efficient enzyme hydrolysis of the treated lignocellulose and new options for valorization in
fermentations.
Lignocelulozna biomasa predstavlja jeftinu sirovinu koja se može koristiti u fermentacionim procesima za dobijanje biogoriva,
biogasa i drugih jedinjenja, zahvaljujući visokom sadržaju ugljenih hidrata. Složena struktura, koja uključuje celulozu, hemicelulozu
i lignin, zahteva prethodni tretman biomase kojim se olakšava hidroliza do prostih šećera. Danas se biomasa samo delimično
eksploatiše i generiše oko 14% energije na svetskom nivou. To je prevashodno zbog male održivosti najčešće korišćenih fizičkih,
hemijskih i fizičko-hemijskih tretmana. Ovi procesi troše veliku količinu energije, imaju malu produktivnost, a toksični sporedni
proizvodi koji nastaju tokom tretmana mogu ometati kasnije korake fermentacije. Tretman biomase naprednim oksidacionim
procesima ima veliki potencijal kao ekološki prihvatljiv, tzv. „zeleni“ tretman. Tokom ovog procesa dolazi do stvaranja reaktivnih
vrsta (radikala, elektrona, jona i peroksida), koje napadaju celulozu, hemicelulozu i lignin. U ovom r...adu upoređeni su efekti
tretmana kukuruzne stabljike netermalnom plazmom, Fentonovim reagensom i kombinovanog tretmana netermalnom
plazmom/Fenton reagensom. Samlevena biomasa kukuruzne stabljike pomešana je sa Fentonovim reagensom i vodonik peroksidom u
različitim odnosima, a zatim je podvrgnuta tretmanu netermalnom plazmom. Sadržaj celuloze i hemiceluloze je značajno smanjen u
uzorcima tretiranim netermalnom plazmom i u prisustvu i u odsustvu Fe2+. Ipak, najveći stepen redukcije lignoceluloze je postignut
pri određenom odnosu biomasa:Fe2+:vodonik peroksid. Primenjeni tretmani su uticali i na hemiceluloznu frakciju, ostavljajući indeks
kristaliničnosti celuloze skoro nepromenjenim. Niži sadržaj lignina i manji indeks kristaliničnosti celuloze omogućavaju efikasniju
enzimsku hidrolizu tretirane lignoceluloze i nove načine za valorizaciju u fermentacionim procesima.
