Paenibacillus quercus sp. nov., isolated from rhizosphere of Quercus aliena var. acuteserrata

Paenibacillus plantiphilus sp. nov. from the plant environment of Zea mays

A Gram-strain positive, aerobic, endospore-forming bacterial strain (JJ-246^T) was isolated from the rhizosphere of Zea mays. The 16S rRNA gene sequence similarity comparisons showed a most closely relationship to Paenibacillus oenotherae DT7-4^T (98.4%) and Paenibacillus xanthinolyticus 11N27^T (98.0%). The pairwise average nucleotide identity and digital DNA-DNA hybridisation values of the JJ-246^T genome assembly against publicly available Paenibacillus type strain genomes were below 82% and 33%, respectively. The draft genome of JJ-246^T shared many putative plant-beneficial functions contributing (PBFC) genes, related to plant root colonisation, oxidative stress protection, degradation of aromatic compounds, plant growth-promoting traits, disease resistance, drug and heavy metal resistance, and nutrient acquisition. The quinone system of strain JJ-246^T, the polar lipid profile and the major fatty acids were congruent with those reported for members of the genus Paenibacillus. JJ-246^T was shown to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus plantiphilus sp. nov. is proposed, with JJ-246^T (= LMG 32093^T = CCM 9089^T = CIP 111893^T) as the type strain.

Paenibacillus allorhizoplanae sp. nov. from the rhizoplane of a Zea mays root

A Gram-positive staining, aerobic, endospore-forming bacterial strain, isolated from the rhizosphere of Zea mays was studied for its detailed taxonomic allocation. Based on the 16S rRNA gene sequence similarity comparisons, strain JJ-42 ^T was shown to be a member of the genus Paenibacillus, most closely related to the type strain of Paenibacillus pectinilyticus (98.8%). The 16S rRNA gene sequence similarity to all other Paenibacillus species was below 98.5%. The pairwise average nucleotide identity (ANI) and digital DNA−DNA hybridization (dDDH) values of the JJ-42 ^T genome assembly against publicly available Paenibacillus type strain genomes were below 92% and 47%, respectively. The quinone system of strain JJ-42 ^T consisted exclusively of menaquinone MK-7. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, three aminophospholipids (APL), and one unidentified lipid. The major fatty acids were iso- and anteiso-branched with the major compound anteiso C_15:0. Physiological and biochemical characteristics allowed a further phenotypic differentiation of strain JJ-42 ^T from the most closely related species. Thus, JJ-42 ^T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus allorhizoplanae sp. nov. is proposed, with JJ-42 ^T (= LMG 32089 ^T = CCM 9085 ^T = DSM 111786 ^T = CIP 111891 ^T) as the type strain.

Bacillus rhizoplanae sp. nov. from maize roots

A Gram-stain-positive, aerobic and endospore-forming bacterial strain, isolated from the root surface of maize (Zea mays) was taxonomically studied. It could be clearly shown that, based on 16S rRNA gene sequence similarity comparisons, strain JJ-63T is a member of the genus Bacillus , most closely related to the type strain of Bacillus pseudomycoides (98.61%), followed by Bacillus cereus (98.47 %). Detailed phylogenetic analysis based on the 16S rRNA gene and the 87 proteins conserved within the phylum Firmicutes placed the strain into the Cereus clade. The average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values against the type strain of B. pseudomycoides were 80.97, 81.45 and 26.30 %, respectively. The quinone system of strain JJ-63T consisted exclusively of menaquinone MK-7. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified glycolipid. Major fatty acids were iso- and anteiso-branched with the major compounds iso-C15 : 0 and iso-C17 : 0. Also, the characteristic compounds C13 : 0 iso and C16 : 1 cis10 were found. Physiological and biochemical characteristics allowed a further phenotypic differentiation of strain JJ-63T from the most closely related species. For this reason, JJ-63T represents a novel species of the genus Bacillus , for which the name Bacillus rhizoplanae sp. nov. is proposed, with JJ-63T (=LMG 32091T=CCM 9090T=DSM 111827T= CIP 111899T) as the type strain.

Paenibacillus allorhizosphaerae sp. nov., from soil of the rhizosphere of Zea mays

A Gram-stain-positive, aerobic, endospore-forming bacterial strain, isolated from the rhizosphere of Zea mays, was studied for its detailed taxonomic allocation. Based on 16S rRNA gene sequence similarity comparisons, strain JJ-447^T was shown to be a member of the genus Paenibacillus, most closely related to the type strain of Paenibacillus solanacearum (97.8 %). The 16S rRNA gene sequence similarity values to all other Paenibacillus species were below 97.0 %. DNA-DNA hybridization (DDH) values with the type strain of P. solanacearum were 35.9 % (reciprocal 27%), respectively. The average nucleotide identity and in silico DDH values with the type strain of P. solanacearum were 84.86 and 28.9 %, respectively. The quinone system of strain JJ-447^T consisted exclusively of menaquinones and the major component was MK-7 (96.4 %) but minor amounts of MK-6 (3.6 %) were detected as well. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminolipid. Major fatty acids were iso- and anteiso-branched with the major compounds anteiso-C_15 : 0 and iso-C_15 : 0. Physiological and biochemical characteristics allowed a further phenotypic differentiation of strain JJ-447^T from the most closely related species on the basis of d-glucose, l-arabinose and d-mannose assimilation and other physiological tests. Thus, JJ-447^T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus allorhizosphaerae sp. nov. is proposed, with JJ-447^T (=LMG 31601^T=CCM 9021^T=CIP 111802^T) as the type strain.

List of new names and new combinations previously effectively, but not validly, published

The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
