Реферат: The effect of culture conditions on the bacterial cellulose (BC) yield synthesized by symbiotic culture Medusomyces gisevii Sa-12 grown in synthetic nutrient medium was studied for the first time. The conditions providing the maximum yield of bacterial cellulose were evaluated: the initial glucose concentration in the culture medium was 20–25 g/L, the temperature was 24–27°C, the ratio of the nutrient medium to the air volume was 1: 10, and the content of the black tea extracts comprised 1.6–4.8 g/L. A sample of chemically pure BC with the following characteristics was obtained under the selected culture conditions: moisture— 99.0%, degree of polymerization—4800, average width of microfibrillar ribbons—30.6 nm, degree of crystallinity— 86%, and the content of triclinic modification Iα—98%.
