Изучение антибактериального и фунгицидного потенциала хитозана является перспективным направлением исследований и имеет достаточно высокое прикладное значение в области применения хитозана, как технологического вспомогательного материала в технологиях вин, пива и напитков брожения с целью элиминации потенциальных мутеобразующих компонентов биологической этиологии. Материалы и методы. Научная задача исследования – оценить антибактериальную и фунгицидную активность хитозана. Определение бактерицидной активности хитозана в отношении E. coli осуществляли методом поверхностного посева на питательную среду Эндо, селективную в отношении БГКП. Результаты и обсуждение. Определение фунгицидной активности в отношении Saccharomyces cereviviae осуществляли методом поверхностного посева на питательную среду сабуро с хлорамфениколом, селективную в отношении дрожжевых грибов. Заключение. Хитозан характеризуется антибактериальной и фунгицидной активностью, выявлено, что добавление хитозана даже в минимальном количестве обеспечивает фунгицидный эффект в отношении тест-культуры дрожжевых грибов S. сereviviae и позволяет значительно усилить бактерицидный эффект в отношении тест-культуры бактерий E.coli.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The study of the antibacterial and fungicidal potential of chitosan is a promising area of research and has a fairly high applied value in the field of using chitosan as a technological auxiliary material in wine, beer and fermented beverage technologies to eliminate potential components of biological mutagenesis. Materials and methods. The scientific objective of the study is to evaluate the antibacterial and fungicidal activity of chitosan. Determination of the bactericidal activity of chitosan against E. coli was carried out by surface inoculation on Endo nutrient medium selective for coliforms. Results and discussion. Determination of fungicidal activity against Saccharomyces cereviviae was carried out by surface inoculation on Sabouraud nutrient medium with chloramphenicol selective for yeast fungi. Conclusion. Chitosan has antibacterial and fungicidal activity. It has been established that the addition of chitosan even in minimal quantities provides a fungicidal effect in relation to the test culture of yeast fungi S. cereviviae and allows to significantly enhance the bactericidal effect in relation to the test culture of bacteria E. coli.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мутеобразующие компоненты биологической природы</kwd><kwd>антибактериальная активность хитозана</kwd><kwd>фунгицидная активность хитозана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>turbidity-forming components of biological nature</kwd><kwd>antibacterial activity of chitosan</kwd><kwd>fungicidal activity of chitosan</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">In vitro antimicrobial activity of a chitooligosaccharide mixture against Actinobacillus actinomycetemcomitans and Streptococcus mutans / B.K.
