JF International Journal of Systematic and Evolutionary Microbiology, VO 67 IS 2 SP 294 OP 300 DO https://doi.org/10.1099/ijsem.0.001618 PB Microbiology Society, SN 1466-5034, AB A Gram-stain-positive, facultatively anaerobic actinomycete, designated strain T6220-5-2bT, was isolated from a sample taken from a mouldy spot on the surface of a mural painting (the white tiger, Byakko) inside the stone chamber of Takamatsuzuka Tumulus in Asuka village, Nara Prefecture, Japan. Based on 16S rRNA gene sequence analysis of the isolate, it was closely related to the genus Promicromonospora , but formed of a novel lineage within the family Promicromonosporaceae . The closest related species to strain T6220-5-2bT was Promicromonospora flava , with which it shared 99.1 % 16S rRNA gene sequence similarity. The isoprenoid quinone systems were menaquinones MK-9(H2), MK-9(H0) and MK-9(H4). The predominant cellular fatty acids for the isolate were anteiso-C15 : 0 and iso-C15 : 0. The peptidoglycan contained glutamic acid, aspartic acid, alanine and lysine, with the last named being the diagnostic diamino acid. The cell-wall acyl type was acetyl. The major polar lipids of the isolate were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositolmannoside, two unknown phospholipids and an unknown phosphoglycolipid. Whole-cell sugars of the isolate were galactose, glucose and ribose. The DNA G+C content of the genomic DNA was 75.2 mol%. Based on the results of phylogenetic, physiological and biochemical analyses and DNA–DNA hybridization experiments, the isolate was considered to represent a novel species of a new genus in the family Promicromonosporaceae , for which the name Krasilnikoviella muralis gen. nov., sp. nov. is proposed. The type strain of Krasilnikoviella muralis is T6220-5-2bT (=JCM 28789T=NCIMB 15040T). The reclassification of Promicromonospora flava as Krasilnikoviella flava comb. nov. is also proposed with the emended description of this species., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001618
