[Production of inoculates for leguminous plants. Production of cellular suspensions of Rhizobium (Lotus group)].

The influence of culture medium composition and operative conditions on the cellular growth of Rhizobium sp (group Lotus) strain is studied. As much as 1 x 10(9) cell/ml were obtained in 16 hours using sucrose in the medium as carbon source. The best growth rate was obtained (mu = O,22 h-1) when the experiments were performed at 400 r.p.m. and one volume of air/volume of medium x minute (OAR = 793,0 ml of oxygen/1 h).
