Gluconic acid is a mild organic acid that has gained much interest as it has many industrial applications such as in the pharmaceutical, food, animal feed and textile industry. It is also applied as additive in cement to control the setting time and increase strength and water resistance, component of photographic developer, and used for alkaline derusting in metallurgy. There are several methods to produce gluconic acid including chemical, electrochemical, biochemical and bioelectrochemical. In this research, batch fermentation of glucose into gluconic acid was done with intial substrate concentration of 150, 200 and 250 g/l. The experimental data resulted was then used to obtain kinetic parameters. The kinetic models used were Contois and Logistic equation for cell growth, Luedeking-Piret equation for gluconic acid formation, and Luedeking-Piret-like equation for glucose consumption.
