AB  - The study reports an effluent-free, green process for the production of materials with favorable antibiofilm properties by cellulose acetate grafting with quaternary ammonium compounds in supercritical carbon dioxide. Two quaternary ammonium compounds, N-(2-Hydroxyethyl)-N,N-dimethylundecan-1-aminium Bromide and N-(11-Hydroxyundecanyl-N,N-dimethyltetradecan- 1-aminium Bromide, were synthesized and chemically attached to cellulose acetate via hexamethylene diisocyanate as a linker under the conditions of 30 MPa and 70 °C. The polymer modification occurred in its whole volume. The chemical conversion led to a decrease in the degree of crystallinity and the appearance of a rugged polymer surface. However, the cross-section imaging of the newly obtained materials revealed a compact polymer structure. The functionalized materials acquired hydrophobic properties. Microbiological tests showed the impossibility of Staphylococcus aureus ATCC 29213, Methicillin-resistant Staphylococcus aureus ATCC 43300, Escherichia coli ATCC 10536, and Salmonella Enteritidis ATCC 13076 attachment to the material obtained by the cellulose acetate grafting procedure with N-(11-Hydroxyundecanyl-N,N-dimethyltetradecan- 1-aminium Bromide.

AB  - There is an urgency to develop novel materials capable of preventing the adherence of microorganisms to
their surface. Such materials with antibiofilm properties are needed in hospitals and public places, animal
farms and veterinary hospitals, and biofouling prevention. Biofouling is the phenomenon of adhesion and
the growth of microorganisms on surfaces in contact with water. It poses a significant problem for filtration
processes, water treatment units, bioreactors, and ships performance (marine biofouling). High-pressure
techniques such as supercritical solvent impregnation and grafting in the supercritical phase allow for the
modification of a solid matrix throughout the whole volume and production of materials of unique
properties in an environmentally friendly way. Grafting involves the chemical attachment of an active
compound to a solid matrix, ensuring its long-lasting properties. Grafting in supercritical carbon dioxide
(scCO2) has been reported as an efficient tool in the production of materials with antibacterial1
, and recently
also antibiofilm properties2
. This study aims to investigate the potential of cellulose acetate (CA) grafting
with quaternary ammonium compounds (QAC) for acquiring antibiofilm properties. Two QAC were
synthesized, and the grafting conditions were investigated. The grafting was performed via hexamethylene
diisocyanate (HDI) as a linker1
. Obtained materials were analyzed using FTIR, SEM and Ion microscopy,
DSC analyses, contact angle measurements, and standardized microbiological procedures to evaluate
antibiofilm properties.

AB  - This study aimed to investigate the potential of the most abundant red grape variety from the central part of Serbia (the region of three Morava rivers) for grape oil manufacturing, using supercritical CO2 extraction. The content of the main constituents of grape seed oils from the indigenous variety Prokupac was determined and the results
of the analysis were compared with selected, most commonly grown, international varieties (Cabernet Sauvignon, Pinot Noir, Merlot, and Gamay). Fatty acid profile and the content of biologically active compounds (total phenolic compounds and αtocopherol) were determined. Oxidative stability of the oils was estimated using a DSC
(differential scanning calorimetry) method, by determining the oxidation onset temperature. The fatty acid composition was in accordance with literature data. In terms of α-tocopherol content, its low relative amount was measured in the oils from all grape seed varieties.

The antibacterial activity of the extracts was compared with the antibacterial activity of xanthohumol, compound known for its broad pharmacological properties, isolated from the raw material remained after the SFE. Xanthohumol (XH, 96%) proved to posses the most prominent activity against all the tested strains, with the MIC values ranged between 2.5 and 20 mu g mL(-1). Supercritical hops extract and potassium isomerized supercritical hops extract showed strong antibacterial activity against the tested strains as well. Escherichia coli was not affected by the extracts, meaning that their oral admission would not cause the same problem as antibiotic application in intestinal flora. The chemical composition of the investigated hops extracts was analysed by GC-MS. Contents of a-acids, beta-acids, iso-alpha-acids and xanthohumol in the samples were determined by HPLC.

AB  - This study discusses the possibility of impregnation of corona pre-treated polypropylene (PP) non-woven fabric with thymol in supercritical carbon dioxide. Corona treatment of PP fibers caused significant morphological changes. FTIR measurements revealed that ester bond between OH group of thymol and carbonyl group of corona treated PP fibers has been established. Antibacterial activity of corona activated PP non-woven fabrics impregnated with thymol was tested against Gram-negative bacteria E. coli and Gram-positive bacteria S. aureus. Maximum bacteria reduction was provided.
