PURPOSE:To produce a large amount of epsilon-poly-L-lysine, by subjecting a strain capable of producing epsilon-poly-L-lysine to mutagenic treatment, thereby establishing a strain capable of producing a large amount of epsilon-poly-L-lysine. CONSTITUTION:A bacterial strain capable of producing epsilon-poly-L-lysine is subjected to mutagenic treatment and the obtained strain capable of producing large amount of epsilon-poly-L-lysine is cultured in a medium to accumulate epsilon-poly-L- lysine in the cultured liquid. The accumulated epsilon-poly-L-lysine is separated from the medium. The strain capable of producing large amount of epsilon-poly-L-lysine is preferably a strain resistant to an L-lysine analog such as S-aminoethyl-L- clysteine. |
