Microbispora catharanthi sp. nov., a novel endophytic actinomycete isolated from the root of Catharanthus roseus. Int J Syst Evol Microbiol. 2019 Nov 15;: Authors: Klykleung N, Yuki M, Kudo T, Ohkuma M, Phongsopitanun W, Pittayakhajonwut P, Tanasupawat S Abstract Strain CR1-09T, an actinomycete isolated from the root of Catharanthus roseus, was taxonomically studied based upon polyphasic approaches. The isolate formed a pair of ovular to circular, smooth-surfaced spores on short sporophores alternately branched from aerial mycelia. It contained meso-diaminopimelic acid in cell wall peptidoglycans. The major menaquinones were MK-9 (H4) and MK-9 (H2). The predominant cellular fatty acids were iso-C16 : 0 and C16 : 0. The polar lipids profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxyl phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, and unidentified ninhydrin positive phosphoglycolipids. Strain CR1-09T showed the highest 16S rRNA gene sequence similarity with Microbispora tritici DSM 104650T (99.5 %). Based on the polyphasic approach, DNA-DNA relatedness and average nucleotide identity (ANI), the strain is considered to represent a novel species of the genus Microbispora, for which the name Microbispora catharanthi is proposed. The type strain is strain CR1-09T (=JCM 30045T=TISTR 2273T). PMID: 31730033 [PubMed - as supplied by publisher]
