Strain Information

Information
Produces L-methionine from whey permeate (Kitamoto HK, Nakahara T, 1994). Degrades whey permeate (Kitamoto HK, Nakahara T, 1994). Hydrolyzes whey lactose (Enzyme Microb. Technol, 1994) Produces L-methionine (Kitamoto HK, Nakahara T, 1994). Produces beta-galactosidase (beta-D-galactosidase) (Dickson RC, Markin JS, 1980; Siso MI, 1994). Produces killer toxin (Gunge N, 1981; Butler AR,1991).
