The experiment took the organic rice bran as the fermentation substrate to study the biologi-cal accumulation function of the yeast to germanium. The biomass and germanium- enriched yeastwere measured for optimizing the experiment conditions. The result showed: under the optimized condi-tions that the initial p H value was unchanged, the filling volume of organic rice bran was 32 g/250 ml,the filling volume of liquid medium was 80 ml/250 ml, the inoculum was 10%(v/v), the cultural timewas 60 h, the cultural temperature was 30 ℃, Ge O2 concentration was 100 mg/l, the organic germani-um production-level of the organic rice bran fermented by yeast was 11.83 mg/kg.
