Fig. 3From: Increasing lysine level improved methanol assimilation toward butyric acid production in Butyribacterium methylotrophicumThe effect of lysine supplementation on the methanol utilization and butyric acid production of B. methylotrophicum. The strain B. methylotrophicum was cultivated in modified DSM135 medium supplemented with extra concentrations of lysine (0Â mM, 5Â mM, 10Â mM, 20Â mM and 30Â mM) anaerobically. The growth profiles (A), the methanol consumption (B), butyric acid production (C), and butyric acid yield (D) were determinedBack to article page
