Cellobiose fermentation by B. coagulans NL01, ATCC 7050, XZL4, and ATCC 7050(ΔcelR). a Time courses of cellobiose consumption. b Time courses of lactic acid production. Red, B. coagulans NL01; Olive, B. coagulans ATCC 7050; Blue, B. coagulans XZL4; Magenta, B. coagulans ATCC 7050(ΔcelR). Fermentations were carried out in 250-mL Erlenmeyer flasks containing 100 mL medium at 50 °C and 150 rpm on a rotary shaker. The medium contained the following (g/L): cellobiose 20, yeast extract 2.5, corn syrup powder 1.2, MgSO4·7H2O 0.4, (NH4)2SO4 3, KH2PO4 0.22, MnSO4·H2O 0.03, FeSO4·H2O 0.03, and CaCO3 10
