Bacterial cellulose produced by members of the genus Gluconacetobacter displays unique properties including high mechanical strength, high water holding ability, high crystallinity, and an ultra-fi ne and highly pure fi ber network structure. It has many potential applications in biomedical, biosensor, food, textile and other industries. A cellulose producing strain isolated from nata sample (a desert) was identifi ed as Gluconacetobacter persimmonis (GH-2) based on biochemical studies and 16S rDNA complete sequence analysis. The strain produced 5.14 g/L of cellulose in standard medium under stationary growth conditions. For effective production of cellulose from the strain, various carbon and nitrogen sources were investigated in fl ask cultures under stationary conditions of incubation. Among various carbon sources glucose, fructose, sucrose, mannitol and .. View More»
