Bacterial cellulose (BC) is a promising material for technological and medical applications. The isolation of effective BC producers from natural symbiotic consortia is a promising direction in relation to industrial biotechnology of BC. The study consists in selecting the composition of the nutrient medium to increase the efficiency of the biosynthesis process of BC by cellulose-synthesizing bacteria isolated from the symbiotic consortium Medusomyces gisevii. Morphological features of isolated acetic acid bacteria have been determined - small rods, 0.8-1.2 microns in size with a rounded end, forming cream-colored colonies on agarized nutrient media, 2-7 mm in size with a characteristic luster. The composition of the nutrient medium RAE (AE) was determined, characterized by the maximum efficiency of BC biosynthesis (production of 4.63 g DM/l for 8 days; the degree of glucose conversion - 41.04%).
