A freshly-prepared yeast extract at 30 or 50 g/l improved the growth o
f Bradyrhizobium japonicum SEMIA 587 in a 5-1 stirred fermenter. Monos
odium glutamate or a commercial yeast extract at 2.0 g/l almost double
d cell mass productivity and cell viability when added at the end of t
he first exponential growth phase.
