Abstract

The taxonomic status of Paenibacillus thermophilus was analyzed using genomic and phenotypic approaches. The results of RNA polymerase beta subunit gene sequence comparisons indicated that two type strains of P. thermophilus (DSM 24746 and JCM 17693) and Paenibacillus macerans ATCC 8244 shared 100 % sequence similarity. By whole-genome sequence comparison, their average nucleotide identity values were over 99.3 %. Investigation of substrate utilization, enzyme activities and cellular fatty acid patterns displayed no striking differences between P. thermophilus JCM 17693 and P. macerans JCM 2500. On the basis of these results, we propose that the name Paenibacillus thermophilus is a later heterotypic synonym of Paenibacillus macerans .
