    • PURPOSE: A method for producing bacterial cellulose using the waste of beer fermentation broth as a culture medium is provided, thereby inhibiting production of mutants which do not produce cellulose, inducing production of a lump form of cellulose to easily isolate it, and reducing the cellulose production costs by using inexpensive waste medium. CONSTITUTION: The method for producing bacterial cellulose using the waste of beer fermentation broth as culture medium comprises culturing a cellulose producing microorganism selected from Acetobacter sp., Gluconacetobacter sp., Agrobacterium sp., Rhizobium sp., Pseudomonas sp. and Sarcina sp. in the waste of beer fermentation broth as a culture medium, wherein the culture is a continuous batch culture. An alternative method for producing bacterial cellulose comprises culturing Gluconacetobacter hansenii PJK(KCTC 10505BP) in a medium containing 0.5 to 15%(v/v) of ethanol.
    • 目的:提供使用啤酒发酵液的废物作为培养基生产细菌纤维素的方法,从而抑制不产生纤维素的突变体的产生,诱导产生块状形式的纤维素以容易地分离纤维素,并且还原纤维素 使用廉价的废料生产成本。 构成:使用啤酒发酵液的废弃物作为培养基生产细菌纤维素的方法包括培养选自醋杆菌属,醋酸杆菌属,土壤杆菌属,根瘤菌属,假单胞菌属, 和Sarcina sp。 在作为培养基的啤酒发酵液的废弃中,其中培养物是连续的分批培养。 用于生产细菌纤维素的替代方法包括在含0.5至15%(v / v)乙醇的培养基中培养汉逊酵母葡萄糖醋杆菌PJK(KCTC 10505BP)。
