Reclassification of Lactobacillus thermotolerans Niamsup et al. 2003 as a later synonym of Lactobacillus ingluviei Baele et al. 2003.
The relatedness of the species Lactobacillus ingluviei and Lactobacillus thermotolerans was investigated by comparing partial sequences of the 16S rRNA gene (99.9 % similarity over 1504 bp), the hsp60 gene (98.8 % similarity over 954 bp) and the recA gene (98.5 % similarity over 452 bp) and by determining DNA-DNA binding levels (79+/-3 %) and genomic DNA G+C contents (50 and 49 mol%, respectively). These data, in addition to their similar biochemical characteristics, suggest that the two taxa constitute a single species. According to Rules 38 and 42 of the Bacteriological Code, they should be united under the name Lactobacillus ingluviei, with the name Lactobacillus thermotolerans as a later heterotypic synonym.
