Abstract
To produce and utilize microbial cellulose being industrially useful, bacterium posessing a high ability to produce cellulose and the uniform structure of cellulose pellicle was isolated from the traditionally fermented vinegar in korea. The isolated strain, GS11 was gram-negative, rod(0.6 x 2.2~3.3 μm) and motile. It also had 58.4% of DNA base composition, posessed straight-chain C(18:l), C(16:0) and C(14:0) fatty acid, and contained ubiquinone Q(10). According to its morphological, physiological and biochemical properties, the isolated strain was identified as Acetobacter xylinum. A. xylinum GS11 was cultured for the study of cellulose productivity during the static culture, 12 days at 30°C. As this result, the amount of glucose was quickly decreased, and then used as substrate for cellulose production. In this culture, the maximal production of cellulose peaked with 2.8 g/l after 8 days.
