摘要: The production of citric acid from carob pod extract byA. niger in surface fermentation was investigated. A maximum concentration (85.5 g/L), productivity (4.07 g/L/d), specific rate (0.18 g/g/d), and sugar uptake (0.358 g/g/d) achieved at an initial 200 g/L, pH 6.5, a temperature 30°C. Other kinetic parameters, namely, yield, biomass rate, efficiency were 30°C, 100 g/L. external addition methanol into the up to 4% (v/v) improved acid.
