- a Batch fermentation was performed in 5 L fermentor containing 3 L medium and cultivated at 55°C controlling pH as 6.5 with 5 M of sodium hydroxide. Data represent the average results from three independent experiments.
- b Carbon recovery accounts for the average of percentage of carbon recovered in all products and biomass at all the time points.
- c The specified time that strain reached the maximum lactic acid concentration.
