Study on High Production of Reuterin by Lactobacillus reutrei

Abstract:

Lactobacillus reutrei can product reuterin with safety and high efficiency. The objective of present study was to investigate the optimal conditions on the biotransformation of glycerol to enhance the yield of reuterin. The biotransformation conditions were optimized by orthogonal tests as follows：glycerol concentration 400 mmol/L，cell concentration 110 g/L，conversion time 2 h，temperature 30 ℃ and pH 6.2. An average yield of reuterin was 241.2±3.4 mmol/L under optimal conditions.
