摘要：
88 g/L lactic acid was produced from waste potato starch (equivalent to 100 g/L glucose) in a bubble column reactor using appropriate acid-adapted precultures of Rhizopus arrhizus. Further experiment showed that repeated dilution of cultures caused the decrease of lactic acid concentration and productivity due to formation of large fungal pellets.
