title: Pseudactinotalea terrae gen. nov., sp. nov., isolated from greenhouse soil, and reclassification of Actinotalea suaedae as Pseudactinotalea suaedae comb. nov.
abstract: A bacterial strain, designated 5GHs33-3T, was isolated from greenhouse soil collected from Yongin region, Gyeonggi province, South Korea. The strain was an aerobic, Gram-stain-positive, flagellated, rod-shaped bacterium. Strain 5GHs33-3T grew at 4-37 °C (optimally at 28-30 °C), pH 6.0-10.0 (optimally at pH 7.0) and with 0-7 % (w/v) NaCl (optimally with 0 %). The 16S rRNA gene sequence analysis revealed that strain 5GHs33-3T had high sequence similarity with Actinotalea suaedae EGI 60002T (98.4 %), Actinotalea ferrariae CF5-4T (96.4 %) and Actinotalea fermentans DSM 3133T (96.2 %), and less than 95.5 % sequence similarity against all the other species with validly published names. The phylogenetic tree revealed that strain 5GHs33-3T formed a robust independent monophyletic line with Actinotalea suaedae EGI 60002T. The predominant fatty acids of strain 5GHs33-3T were anteiso-C15 : 0 and iso-C14 : 0. The only quinone was MK-8(H4). Polar lipids were diphosphatidylglycerol, phosphatidylinositol, an unknown phosphoglycolipid and unknown lipids. The peptidoglycan type was A4β, with ornithine as the diagnostic diamino acid and an interpeptide bridge comprising l-Glu. The DNA G+C content is 69.0 mol%. Based on phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses, strain 5GHs33-3T represents a novel species of a new genus of the family Cellulomonadaceae, for which the name Pseudactinotalea terrae gen. nov., sp. nov. is proposed. The type strain of the type species is 5GHs33-3T (=KACC 16542T=NBRC 111006T). We also propose the reclassification of Actinotalea suaedae as Pseudactinotalea suaedae comb. nov. (type strain EGI 60002T=JCM 19624T=KACC 17839T=KCTC 29256T).
