 Actinoplanes oblitus sp. nov., producing the glycopeptide antibiotic A477
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006225.ABSTRACTIn 1973, Eli Lilly and Company described the filamentous actinomycete producing the glycopeptide antibiotic A477 as an Actinoplanes species on the basis of its morphological and physiological features and deposited it as NRRL 3884T. In this paper, we report that the phylogenetic analysis based on the 16S rRNA gene sequence and the whole genome phylogenomic study indicate that NRRL 3884T forms a distinct monophyletic line within the genus Actinoplanes, being most closely related to Actinoplanes octamycinicus NBRC 14524T [99.6 % 16S rRNA gene simi...

Comamonas resistens sp. nov. and Pseudomonas triclosanedens sp. nov., two members of the phylum Pseudomonadota isolated from the wastewater treatment system of a pharmaceutical factory
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006222.ABSTRACTFive strains of two novel species were isolated from the wastewater treatment systems of a pharmaceutical factory located in Zhejiang province, PR China. Strains ZM22T and Y6 were identified as belonging to a potential novel species of the genus Comamonas, whereas strains ZM23T, ZM24 and ZM25 were identified as belonging to a novel species of the genus Pseudomonas. These strains were characterized by polyphasic approaches including 16S rRNA gene analysis, multi-locus sequence analysis, average nucleotide identity (ANI), in silico DNA-DNA hybridi...

 Comamonas endophytica sp. nov., a novel indole acetic acid producing endophyte isolated from bamboo in China
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006217.ABSTRACTTwo novel indole acetic acid-producing strains, 5MLIRT and D4N7, were isolated from Indosasa shibataeoides in Yongzhou, Hunan province, and Phyllostachys edulis in Hangzhou, Zhejiang province, respectively. Based on their 16S rRNA sequences, strains 5MLIRT and D4N7 were closely related to Comamonas antarcticus 16-35-5T (98.4 % sequence similarity), and the results of 92-core gene phylogenetic trees showed that strains 5MLIRT and D4N7 formed a phylogenetic lineage within the clade comprising Comamonas species. The complete genome size of strain 5...

 Spencermartinsiella henanensis fa., sp. nov., a novel yeast species isolated from rotting wood
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006226.ABSTRACTTwo yeast strains (NYNU 211162 and NYNU 211275) were isolated from rotting wood collected in the Baotianman Nature Reserve, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region revealed that the strains represent a phylogenetically distinct species within the genus Spencermartinsiella. The name Spencermartinsiella henanensis fa., sp. nov. is proposed for this species with holotype CICC 33543T (Mycobank MB 851142). S. henanensis sp. nov. diff...

 Devosia rhodophyticola sp. nov. and Devosia algicola sp. nov., isolated from a marine red alga
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006223.ABSTRACTTwo Gram-stain-negative, obligately aerobic, motile rod bacteria, designated as G2-5T and G20-9T, exhibiting catalase- and oxidase-positive activities, were isolated from the phycosphere of a Chondrus species, a marine red alga. Strain G2-5T exhibited optimal growth at 30 °C and pH 5.0-6.0 and in the presence of 0.5-1.0% NaCl. In contrast, strain G20-9T demonstrated optimal growth at 25 °C and pH 6.0 and in the presence of 0.5-1.5% NaCl. Both strains contained ubiquinone-10, summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C18 : 0 and 11...

 Microbacterium memoriense sp. nov., a member of the Actinomycetota from marine beach sediment of the north coast of Portugal
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006230.ABSTRACTThe oceans harbour a myriad of unknown micro-organisms that remain unstudied because of a failure to establish the right growth conditions under laboratory conditions. To overcome this limitation, an isolation effort inspired by the iChip was performed using marine sediments from Memória beach, Portugal. A novel strain, PMIC_1C1BT, was obtained and subjected to a polyphasic study. Cells of strain PMIC_1C1BT were Gram-positive, rod-shaped, divided by binary fission and formed colonies that were shiny light-yellow. Based on its full 16S rRNA gene...

Spirochaete genome identified in red abalone sample represents a novel genus Candidatus Haliotispira gen. nov. within the order Spirochaetales 
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006198.ABSTRACTA fully assembled spirochaete genome was identified as a contaminating scaffold in our red abalone (Haliotis rufescens) genome assembly. In this paper, we describe the analysis of this bacterial genome. The assembled spirochaete genome is 3.25 Mb in size with 48.5 mol% G+C content. The proteomes of 38 species were compared with the spirochaete genome and it was discovered to form an independent branch within the family Spirochaetaceae on the phylogenetic tree. The comparison of 16S rRNA sequences and average nucleotide identity scores between th...

 Talaromyces mellisjaponici sp. nov., a xerophilic species isolated from honey in Japan
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006212.ABSTRACTFive isolates of a xerophilic Talaromyces species were obtained from honey in Japan. Molecular phylogenetic analysis based on a combined dataset for four regions (rRNA internal transcribed spacer, β-tubulin, calmodulin and RNA polymerase II second largest subunit) revealed that the strains formed an independent clade in section Trachyspermi, which is sister to Talaromyces affinitatimellis, Talaromyces basipetosporus and Talaromyces speluncarum. The strains and their relatives have different growth on creatine agar, yeast extract sucrose agar an...

The best of both worlds: a proposal for further integration of Candidatus names into the International Code of Nomenclature of Prokaryotes
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006188.ABSTRACTThe naming of prokaryotes is governed by the International Code of Nomenclature of Prokaryotes (ICNP) and partially by the International Code of Nomenclature for Algae, Fungi and Plants (ICN). Such codes must be able to determine names of taxa in a universal and unambiguous manner, thus serving as a common language across different fields and activities. This unity is undermined when a new code of nomenclature emerges that overlaps in scope with an established, time-tested code and uses the same format of names but assigns different nomenclatura...
