	Abstract

Poly--glutamate (PGA) is a chiral polyamide material that possesses nylon-like backbone: a bio-nylon polymer. We examined the PGA productivity of Bacillus megaterium and found NaCl-responsive PGA production in bacteria. In the system of B. megaterium, salt would be significant in controlling the yield, molecular size and stereochemistry of bio-nylon.
