Arenimonas caeni sp. nov., isolated from activated sludge Liu, Hongming and Ren, Lei and Lu, Peng and Sun, Lina and Zhu, Guoping,, 68, 2996-3000 (2018), doi = https://doi.org/10.1099/ijsem.0.002937, publicationName = Microbiology Society, issn = 1466-5026, abstract= A Gram-stain-negative, non-spore-forming, motile and rod-shaped strain, z29T, was isolated from the active sludge of a municipal wastewater treatment plant at Wuhu, Anhui, PR China. Phylogenetic analysis of the 16S rRNA gene revealed that strain z29T is most closely related to the genus Arenimonas , showing the highest similarity to Arenimonas donghaensis HO3-R19T (97.14 %), Arenimonas aestuarii S2-21T (96.46 %), Arenimonas daejeonensis T7-07T (96.24 %) and Arenimonas taoyuanensis YN2-31AT (96.23 %). The only respiratory quinone of strain z29T was ubiquinone 8 (Q-8). The major cellular fatty acids (>10 %) were iso-C15 : 0, iso-C16 : 0 and summed feature 9 (iso-C17 : 1ω9c and/or C16 : 010-methyl). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The genomic DNA G+C content was 70.2 mol%. Genomic comparison between strain z29T and Arenimonas donghaensis HO3-R19T revealed 83.72 % average nucleotide identity. Based on the phenotypic and chemotaxonomic results together with phylogenetical analysis, strain z29T is classified as representing a novel species of the genus Arenimonas , for which the name Arenimonas caeni sp. nov. is proposed. The type strain is z29T (=JCM 32091T=CCTCC AB 2017067T)., language=, type=
