Abstract

Lactobacillus casei Zhang was a new probiotic bacterium isolated from traditional home-made koumiss in Inner Mongolia of China. Previously, we have announced its genome sequencing project. Here, to systematically investigate the probiotic genetic basis and reveal the genomic features that contribute to ecological adaptability of L. casei Zhang, we analyzed its genome and made the full comparative analysis with other sequenced lactic acid bacteria (LAB) genomes. Thirty-one phosphotransferase systems (PTSs) were identified in the genome, which was strikingly more abundant than in other lactic acid bacteria (LAB) species and was reflecting the flexibility of L. casei Zhang in sugar utilization. In addition, identification of two eps clusters revealed the genetic basis of exopolysaccharides (EPSs) biosynthesis. The comparative genome studies on L. casei Zhang provided some insights into the genetic basis of its probiotic properties and revealed its value for industrial use.
