摘要：
Strains produce a C2 prod. acetate free and pref. a C3 prod. comprising more than 95% L-lactate and less than 5% D-lactate. Pref. new strains are DSM 6037 and DSM 6129 producing almost exclusively L.lactate and EtOH when cultured on glucose. They were isolated by diluting a sourdough sample with saline (1:10), centrifuging, plating the supernatant on MRS agar, incubating anaerobically at 37 deg.C for 2-3 days, repeatedly, subculturing the colonies, and testing obtd. pure strains for positive reaction with D-fructose, D-glucose, lactose, maltose, melibiose, D-raffinose and sucrose. USE - Prodn. of rye bread by the sourdough method.
