 Peiella sedimenti gen. nov., sp. nov., a novel taxon within the family Caulobacteraceae isolated from sediment of a river
Int J Syst Evol Microbiol. 2024 Apr;74(4). doi: 10.1099/ijsem.0.006344.ABSTRACTA Gram-stain-negative bacterium, designated XZ-24T, was isolated from sediment of a river in Mianyang city, Sichuan province, PR China. Cells (1.0-2.0 µm long and 0.4-0.5 µm in width) were strictly aerobic, non-spore-forming, rod shaped, prosthecate and motile by means of a polar flagellum. Growth occurred at 10-37 °C (optimum, 30 °C), at pH 5.0-9.0 (optimum pH 7.0) and with 0-3.0 % (w/v) NaCl (optimum 1.0 % NaCl).

Int J Syst Evol Microbiol. 2024 Apr;74(4). doi: 10.1099/ijsem.0.006349.ABSTRACTThree Gram-stain-negative, aerobic, non-motile and coccobacilli-shaped bacterial strains, designated as NPKOSM-4T, NPKOSM-8 and MO-31T, were isolated from rice paddy soil. They had 96.5-100 % 16S rRNA gene sequence similarity to each other, and strains NPKOSM-4T and NPKOSM-8 showed 100 % 16S rRNA gene sequence similarity, confirming that they were the same species. Comparative analysis of 16S rRNA genes with closely related type strains showed that three isolates were most closely related to Falsiroseomonas terricola EM0302T (96.1-97.8 %), Falsi...

Arcicella gelida sp. nov. and Arcicella lustrica sp. nov., isolated from streams in China and re-examining the taxonomic status of all the genera within the families Spirosomataceae and Cytophagaceae 
Int J Syst Evol Microbiol. 2024 Apr;74(4). doi: 10.1099/ijsem.0.006345.ABSTRACTThree Gram-stain-negative, aerobic, rod-shaped, non-motile strains (DC2WT, DC25WT, and LKC2W) were isolated from streams in China. Comparisons based on the 16S rRNA gene sequences showed that these three strains share 16S rRNA gene sequence similarity values over 97.0 % with the species of genus Arcicella. There was confusion due to the fact that all species of genera Flectobacillus, Aquirufa, and Sandaracinomonas show 16S rRNA gene sequence similarity of over 90.0 % to the above three strains, but the genus Flectobacillus belongs to the family ...
