Abstract

The effect of dissolved oxygen concentration on the growth and citric acid production by acetate mutant of Y. lipolytica GW-7 on glucose syrup in batch culture were investigated. The highest specific biomass growth rate ( 0,40–0,41 h^-1), volumetric citric acid production rate (1,0–1,1 g dm^-3h^-1) and citric acid yield (0,7–0,74 gg^-1) were obtained at dissolved oxygen concentration of 50–60% pO₂. A final citric acid concentration ranged from 43 to 52,5 g dm^-3, depending on dissolved oxygen concentration.
