Appl. Microbiol., we proposed the revision of the genus Geobacillus, resulting in a new genus Par- ageobacillus. However, the names of the new combinations, G. thermoleovorans, P. caldoxylosilyticus, P. thermoglucosidans, P. ther- mantarcticus and P. toebii, do not conform to rules 27 and 30 of the International Code of Nomenclature of Prokaryotes. In con- sequence, we have included the type strain information in this corrigendum. We have also removed the invalid species, G. zali- hae, from the emended description of Geobacillus and corrected the description of G. thermoleovorans comb. nov. and Parageobacillus genomospecies 1. The authors would like to apologise for any inconvenience caused. Emended description of Geobacillus Nazina et al., 2001, emend. Coorevits et al., 2012 Geobacillus (Ge.o. ba.cil’lus. Gr. n. Gê the Earth; L. dim. n. bacillus small rod; N.L. masc. n. Geobacillus earth or soil small rod). The genus comprises of the genomospecies G. thermoleovo- rans, “G. thermocatenulatus”, G. jurassicus, G. stearothermophilus, G. icigianus, G. thermodenitrificans, G. subterraneus and Geobacillus genomospecies 1, 2 and 3. Morphological and biochemical features as described in the emended description of Geobacillus by Coore- vits et al. [1]. The phylogenetic positions of members of the genus is shown in Figs. 1 and 2. The genomic G + C content of the “genomo- species” ranges from 48.8 to 53.1%. The type species is Geobacillus stearothermophilus.

Description of Parageobacillus gen. nov Parageobacillus (Pa.ra.ge.o.ba.cil’lus. Gr. prep. para, beside or alongside of; Gr. n. Gê the Earth; L. dim. n. bacillus small rod; N.L. masc. n. Parageobacillus, a genus nearest to Geobacillus). As delineation of strains within clade II (Figs. 1 and 2) is pos- sible based on several genome-based metrics highlighted in this work, it is proposed to designate a novel genus Parageobacillus. The genus incorporates five “genomospecies”, P. caldoxylosilyticus, P. thermoglucosidasiu, P. thermantarcticus, P. toebii and Parageobacillus genomospecies 1 (NUB3621). The phylogenetic positions of mem- bers of the genus is shown in Figs. 1 and 2. The genomic G + C contents of the “genomospecies” ranges from 42.1 to 44.4%. The type species is Parageobacillus thermoglucosidasius.

The description of Parageobacillus caldoxylosilyticus comb. nov. is identical to that given for the new genus and to the description given by Fortina et al. [2]. The type strain is S1812 T = DSM 12041 = ATCC 700356. Description of Parageobacillus thermoglucosidasius comb. nov.
