Beschreibung
Zusammenfassung:	The invention belongs to the technical field of microbial fermentation, and particularly relates to bacillus albicans GXU-2 and a method for producing gamma-polyglutamic acid by using the same. The invention provides a strain of bacillus albus GXU-2 which is biologically preserved, and the preservation number is CGMCC (China General Microbiological Culture Collection Center) No.24579. When the bacillus albus GXU-2 provided by the invention is used for fermenting, the high yield of gamma-polyglutamic acid can be achieved, the yield reaches 70 g/L or above, and a new method is provided for biosynthesis of gamma-polyglutamic acid. 本发明属于微生物发酵技术领域，具体涉及一株白色芽孢杆菌GXU-2及利用其生产γ-聚谷氨酸的方法。本发明提供了一株白色芽孢杆菌GXU-2(Bacillus albus)GXU-2，已进行生物保藏，保藏编号为CGMCC No.24579，利用本发明提供的白色芽孢杆菌GXU-2发酵，能高产γ-聚谷氨酸，产量达到70g/L以上，为γ-聚谷氨酸生物合成提供一种新的方法。
