| titleOfInvention | Method for producing gamma-polyglutamic acid though hot fermentation of bacillus subtilis |
| abstract | The invention discloses a method for producing gamma-polyglutamic acid though hot fermentation of bacillus subtilis. A bacterial strain of bacillus subtilis (Bacillussubtilis) GXA-28 with a preservation serial number of CCTCCNO:M2012347 is used for preparation of the gamma-polyglutamic acid through actication of culture, preservation, seed liquid preparation, liquid shake flask fermentation and gamma-polyglutamic acid extraction and purification. the method can widely use low-cost carbon nitrogen sources, such as molasses and inorganic ammonium salt, wherein the inorganic ammonium salt can serve as a sole nitrogen source, the gamma-polyglutamic acid can be efficiently produced at a 40-50 DEG C hot fermentation condition, fermentation time is 18-25h, highest output can achieve 20-30g/l, a production rate can achieve 0.9-1.3g/l.h, and the method has the advantages of being high in efficiency and low in cost. |
