A Method for Manufacturing Highly-Concentrated Polyglutamic Acid with Additional Supply of Saccharides

摘要

The present invention relates to a method for producing a high concentration of polyglutamic acid comprising the step of using the aerobic microorganism Bacillus microorganism and additionally supplying sugars. The high concentration production method of polyglutamic acid of the present invention additionally supplies saccharides to a medium for culturing Bacillus microorganisms, and cultivates Bacillus microorganisms in a fed-batch or batch method, thereby producing high concentrations of polyglutamic acid without high production of by-products. Provide a way to produce. Since the high concentration production method of polyglutamic acid of the present invention can be applied on a large scale, it is possible to economically mass-produce polyglutamic acid.
