 Actinoplanes pyxinae sp. nov., a new lichen-derived rare actinobacterium exhibiting antimicrobial and anticancer activity
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006215.ABSTRACTA novel lichen-derived actinobacterium, designated Pm04-4T, was isolated from Pyxine cocoes (Sw.) Nyl. lichen collected from Chaiyaphum, Thailand. A polyphasic approach was used to describe the taxonomic position of the strain. The strain had morphological and chemotaxonomic properties similar to members of the genus Actinoplanes. It produced sporangia on the substrate mycelia. Meso-diaminopimelic acid, galactose, glucose and mannose were detected in the whole-cell hydrolysate of the strain. The major menaquinone was MK-9(H4). The polar lipids w...

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...

 Shewanella goraebulensis sp. nov., isolated from sea water
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006214.ABSTRACTA novel Gram-stain-negative, facultatively anaerobic and rod-shaped bacterial strain, designated as DAU312T, was isolated from the sea water of the eastern coast of the Republic of Korea. Optimal growth was observed at 25 °C, pH 7.0-8.0 and with NaCl concentrations of 2.0 % (w/v). Catalase and oxidase activities were detected. On the basis of 16S rRNA gene sequences, strain DAU312T showed the highest similarity (99.2 %) to the type strain Shewanella electrodiphila MAR441T. The complete genome sequence of strain DAU312T contains 4 893 483 bp and...

 Acidovorax benzenivorans sp. nov., a novel aromatic hydrocarbon-degrading bacterium isolated from a xylene-degrading enrichment culture
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006219.ABSTRACTA Gram-stain-negative strain, designated as D2M1T was isolated from xylene-degrading enrichment culture and characterized using a polyphasic approach to determine its taxonomic position. The 16S rRNA gene sequence analysis revealed that strain D2M1T belongs to the genus Acidovorax, with the highest 16S rRNA gene similarity to Acidovorax delafieldii DSM 64T (99.93 %), followed by Acidovorax radicis DSM 23535T (98.77 %) and Acidovorax kalamii MTCC 12652T (98.76 %). The draft genome sequence of strain D2M1T is 5.49 Mb long, and the G+C content of t...

Proposal of three novel insect-associated Commensalibacter species: Commensalibacter melissae sp. nov., Commensalibacter communis sp. nov. and Commensalibacter papalotli sp. nov
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006224.ABSTRACTA recent modification of the Note to Rule 25a of the International Code for Nomenclature of Bacteria is used a posteriori by the List Editors of the International Journal of Systematic and Evolutionary Microbiology to justify the refusal to validate species protologues published in supplementary material prior to this formal decision. Authors are therefore forced to ask permission to reuse published data for the valid publication of such names. In the present letter we re-publish the species protologues of Commensalibacter melissae sp. nov., Com...

 Actinoplanes sandaracinus sp. nov. , a novel ligninase- producing and cellulose-degrading actinobacterium isolated from soil
Int J Syst Evol Microbiol. 2024 Jan;74(1). doi: 10.1099/ijsem.0.006216.ABSTRACTA novel ligninase-producing and cellulose-degrading actinobacterium, designated strain NEAU-A12T, was isolated from a soil sample collected from Aohan banner, Chifeng City, Inner Mongolia Autonomous Region, PR China. A polyphasic taxonomic study was used to establish the status of strain NEAU-A12T. 16S rRNA gene sequence analysis revealed that strain NEAU-A12T belonged to the genus Actinoplanes and showed the highest similarity (98.3 %) to Actinoplanes palleronii DSM 43940T, while showing less than 98.3 % similarity to other members of the genus...
