Abstract: | A rumen strain ofMegasphaera elsdenii was grown on glucose and lactate in monensin-free and monensin-supplemented medium (10 mg/L). Monensin had no effect on growth
rate, growth yields, metabolic pattern and composition of cells. Growth yields of dry matter and protein were higher in cultures
supplied with glucose than in cultures supplied with lactate. The bacterium compensated the lower gain of energy from fermentation
of lactate by rapid utilization of this substrate. Cells grown on glucose contained more saccharide and less protein than
lactate-grown cells. |
