Isolation of New Variants of Surfactin by a Recombinant Bacillus-Subtilis
A recombinant Bacillus subtilis MI113(pC115), carrying a gene responsible for the production of surfactin and iturin A cloned from B. subtilis RB14C, produced new surfactin variants, in addition to the already reported surfactin, when MI113(pC115) was cultured in solid-state fermentation of soybean curd residue (okara) as a substrate, All variants isolated by HPLC were characterized.
