| Abstract: | With R-188 the mutant of Rhizopus oryzae as strain and corn powder as raw material, four successive tests of -calcium lactate production are carried out on a fermentation tank of 700 litre. The results show an average lactic acid yeild of 0. 95 mol. L-1, a volumetric productivity of 1. 18 g.L-1.h-1, a corn consumption of 1. 03 kg per kg of L-calcium lactate, and an average extraction tate of 81. 8 %. |

| Keywords: | Rhizopus corn powder L-calcium lactate |
