Abstract
|
|
|
|
In order to obtain the highest productivity of polysaccharide, acetic acid bacteria was used. Several acetic acid bacteria were investigated to the productivity of polysaccharide, an mutant, Acetobacter pasteurianus IFO 13751-5 selected among serveral acetic acid bacteria which can produce the polysaccharide by radiation of ultra-violet ray. Acetobacter pasteurianus IFO 13751-5 was shown 3 fold polysaccharide production than that of its parents. When the Acetobacter pasteurianus IFO 13751-5 was investigated under the condition of carbon source containing 5%r sucrose, the highest amount of polysaccharide (45.95 mg/ml) was obtained. The polysaccharide production by Acetobacter pasteurianus IFO 137515 was 55.10 mg/ml by using jar fermentor.
