Abstract

The pgsBCA-gene disruptant from Bacillus subtilis ISW1214, i.e., MA41, does not produce poly-gamma-glutamate (PGA). We newly constructed an MA41 recombinant bearing the plasmid-borne PGA synthetic system, in which PGA production was strictly controlled by the use of xylose. Unlike the parent strain, ISW1214, the genetically engineered strain produced abundant PGA in both L-glutamate-rich and D-glutamate-rich media.
