Analysis of the <i>Lactobacillus</i> Metabolic Pathway

Abstract

We performed analyses of the phenotypic and genotypic relationships focusing on biosyntheses of amino acids, purine/pyrimidines, and cofactors in three Lactobacillus strains. We found that Lactobacillus fermentum IFO 3956 perhaps synthesized para-aminobenzoate (PABA), an intermediate of folic acid biosynthesis, by an alternative pathway.
