  • a All FAME, ARDRA, and 16S rRNA gene sequence data were considered.

  • b P. lactis, B. farraginis, B. fortis, and B. fordii were described as new species following their isolation in this study (36, 38).

  • c Strain R-6685 could not be attributed to the three new species B. farraginis, B. fortis, and B. fordii (38) and is therefore designated as Bacillus sp.

  • d Four strains (R-6440, R-6441, R-6449, and R-6461) clustered together with P. lactis isolates in FAME but are reported as Paenibacillus sp. because a taxonomic study excluded them from P. lactis (36).

  • e Strains which held a single position in the FAME clustering of a given sample category and were not further analyzed or strains which clustered together with B. sporothermodurans strains in FAME but reacted negatively in a PCR with the primers described by Scheldeman et al. (37).
