| Abstract: | Summary Citric acid yields of Yarrowia lipolytica (NRRL Y-1095) grown on glucose ranged from 0.38–0.77 g/g and were dependent on both biomass and nitrogen concentration (as NH4Cl and yeast extract). Increasing the biomass concentration by 3% (w/v) increased fermentor productivities from 0.6 to 1.22 g citric acid/L h. |
