Response surface methodology was applied for the simultaneous optimization of initial pH and temperature of fermentation for the production of tartaric acid by Gluconobacter suboxydans. A temperature of 32.8 °C and an initial pH of 6.05 was found to be most suitable. Kinetic analysis for the growth of Gluconobacter suboxydans and product formation was done and a logistic model was used to describe the growth of Gluconobacter suboxydans while the Leudeking-Piret model explained the product formation. Parameters of the model were evaluated and tartaric acid formation was found to be non- growth associated.
