Abstract

Bacterial cellulose (BC) is a promising biopolymer with unique properties that make it possible towidely use it in biomedicine, tissue engineering, electrical engineering, food and textile industries. Theaim of a work was to determine the productivity of bacterial cellulose biosynthesis by propagation ofa producer strain on media on the basis of agricultural and food wastes. In present work, the effect of various culture media on strain productivity and structural properties of BC was studied. Three types offermentation media on the basis of agro- and food-processing wastes were used. The productivity of thestrain was evaluated according to biomass yield and BC weight by gravimetric method. The morphologyof BC films was studied by SEM method, and mechanical characteristics – by «Instron» tensile machine.The maximum yield of BC – 8.21+0.02 g/l was achieved by cultivating of a producer on medium containing wastes of sugar production – molasses. The resulting materials formed on classical HS mediumand industrial waste media had an interconnected porous matrix structure with a large surface area.Micro- (15-35 nm) and macrofibrils (50-150 nm) in BC films formed on a medium with molasses joinedinto ribbon-like fibers, providing high mechanical strength (tensile strength: 37.12+0.2, elongation :3.28+0.2%).Key words: bacterial cellulose, fermentation medium, Gluconacetobacter xylinus, industrial wastes
