Abstract

We studied the DNA base composition and DNA-DNA hybridization of 41 strains of spore-forming, lactic acid-producing bacteria including
Sporolactobacillus inulinus. The DNA base composition of 41 strains studied ranged from 42.4 to 50.2mol% guanine plus cytosine. The DNA of S. inulinus NRIC 1133T showed extremely low homology (1 to 5%) to the strains of Lactobacillus plantarum and Bacillus coagulans, but it showed somewhat higher homology to "Bacillus laevolacticus, " "Bacillus racemilacticus, " "Sporolactobacillus laevas, " "Sporolactobacillus laevas var, intermedius, " and "Sporolactobacillus racemicus" (20-50%). Catalase-negative strains of spore-forming lactic acid bacteria, including the type strain of S. inulinus, showed relatively high homology values to one another and further divided into five groups and considered to be members of the genus Sporolactobacillus.
