Fermentation Kinetics of Organic Solvent-stable Protease Production

Abstract

Abstract: Metabolic characteristics and the synthesis of organic solvent-stable protease during batch fermentation of Bacillus aquaemaris DS1 were investigated. The production of organic solvent-stable protease was partially associated with the growth of Bacillus aquaemaris DS1. Based on the results of batch fermentation experiments, the Logistic equation and Luedeking-Piret equation were used to establish kinetic models for bacterial growth, organic solvent-stable protease production and substrate consumption. Good agreement was observed between the experimental and the predicted data of residual sugar concentration with a relative error of less than 10%.

Key words: organic solvent-stable protease, Bacillus aquaemaris DS1, fermentation kinetic model, marine bacteria
