“…Above 33.0 °C the high negative value of the temperature coefficient indicated a rapid decrease in the growth rate with increasing temperature. Subsequent cultivations of C. utilis were conducted at 30.0 °C, which was also the temperature used by others [34,38], seeing that the temperature coefficient was the lowest within the temperature range from 29.1 °C to 33.0 °C (Table 2).…”

The growth of Candida utilis NRRL Y-1084 in acid and enzymatic hydrolysates of cassava peel and on glucose in a mineral salts medium was investigated in aerobic submerged cultivation. Kinetic and stoichiometric parameters for growth were determined. The cardinal temperatures of this yeast strain were 14 °C, 33 °C and 41 °C. C. utilis exhibited no absolute requirement for growth factors, although its maximum specific growth rate (μ max) was higher in the mineral salts medium with yeast extract than without, but its biomass yield coefficient (Y x/s) did not differ much in these two media. In the enzymatic hydrolysate, its Y x/s value on sugar was 0.44 with a μ max of 0.35 h-1 , whereas the corresponding values were 0.52 and 0.48 h-1 in the acid hydrolysate and 0.50 and 0.37 h-1 in the mineral salts medium without yeast extract. The crude protein content of biomass grown in the glucose medium and the acid and enzymatic hydrolysates were 47.5%, 49.1% and 56.7%, respectively. The amino acid profile of the yeast biomass compared favourably with the FAO standard. Cassava peel hydrolysate has potential as a cheap carbohydrate feedstock for the production of yeast single cell protein by using C. utilis.

Treatment of Cassava whey with AspergiIlzcs niger was investigated. Heated cassava whey supplemented with ammonium sulphate (NH,),SO, and potassium di-hydrogen phosphate (KH,PO,) called supplemented cassava whey (SUCW) ; heated but unsupplemented cassava whey (USCW) ; and cassava whey as is, unsupplemented and unheated (UHCW), were used as waste sources and growth media. Total reducing sugars, starch, total carbohydrate, specific gravity, hydrocyanic acid (HCN), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of A. niger inoculated samples and uninoculated set were monitored on a time course basis for 5 days using standard methods. Percentage reductions in the BOD and COD were 69.7 and 54.5 respectively for SUCW samples; 42.4 and 29.5 for USCW samples while values for UHCW were 9.0 and 4.5. The reductions in reducing sugars, starch, total carbohydrate, specific gravity and cyanide content in descending order were SUCW; USCW and UHCW. The heated and A. niger inoculated cassava whey samples were better purified than both the unheated but inoculated and unheated m d uninoculated cassava whey samples.
