In this paper,the melanin produced by the batch fermentation of Plectania YM421 and fermentation kinetics are studied.The kinetic model is built to describe the cell growth,melanin production and substrate consumption based on Logistic equation and Luedeking-Piret equation.The model shows kinetic properties in the production process of melanin by batch fermentation.The calculated results of model fits well with the experimental data.The kinetic model is of practical significance to guide the melanin production by the fermentation of Plectania YM421.
