S. Nakayama et al., ISOLATION OF NEW VARIANTS OF SURFACTIN BY A RECOMBINANT BACILLUS-SUBTILIS, Applied microbiology and biotechnology, 48(1), 1997, pp. 80-82
A recombinant Bacillus subtilis MI113(pC115), carrying a gene responsi
ble for the production of surfactin and iturin A cloned from B. subtil
is RB14C, produced new surfactin variants, in addition to the already
reported surfactin, when MI113(pC115) was cultured in solid-state ferm
entation of soybean curd residue (okara) as a substrate, All variants
isolated by HPLC were characterized.
