Optimization of fermentation conditions for production of l-arabinose isomerase of Lactobacillus plantarum WU14.

ABSTRACT: As a substitute sweetener for sucrose, d-tagatose is widely used in products, such as health drinks, yogurt, fruit juices, baked goods, confectionery, and pharmaceutical preparations. In the fermentation process of l-AI produced by Lactobacillus plantarum, d-tagatose is produced through biotransformation and this study was based on the fermentation process of Lactobacillus plantarum WU14 producing l-AI to further research the biotransformation and separation process of d-tagatose. The kinetics of cell growth, substrate consumption, and l-arabinose isomerase formation were established by nonlinear fitting, and the fitting degrees were 0.996, 0.994, and 0.991, respectively, which could better reflect the change rule of d-tagatose biotransformation in the fermentation process of L.
