Depending on the medium used, the addition of zinc or zinc plus iron to a combination of calcium plus manganese switches the fermentation from glucose accumulation to biomass (single cell protein) production. Complete starch hydrolyzation was obtained in both cases, with a complete glucose utilization resulting in 24 g biomass containing 30% true protein per 100 g cassava starch (= 7.45 g SCP/100 g substrate) in 24 hours. In the case of glucose accumulation, biomass was kept low and 15.5 g/l glucose representing 57.3% of starch supplied were obtained in 36 hours. R. oligosporus UQM 145 F grows well between 30° and 45°C. At 45°C and pH 5.0, 7.0 g SCP/100 g substrate were obtained, which rose to 8.6 g if cassava starch is replaced by ground cassava tuber.Read More
