Comparative genomic and metabolic analysis of three Lactobacillus paracasei cheese isolates reveals considerable genomic differences in strains from the same niche.

Abstract excerpt

BACKGROUND: Strains of Lactobacillus paracasei are present in many diverse environments, including dairy and plant materials and the intestinal tracts of humans and animals. Their adaptation to various niches is correlated to intra-species diversity at the genomic and metabolic level. In this study, we compared the genome sequences of three L. paracasei strains isolated from mature Cheddar cheeses, two of which...
