Abstract
An endophytic actinobacterium, designated strain CA1R205T, was isolated from the surface-sterilized root of Coffea arabica L. collected from Ratchaburi province, Thailand. The taxonomic position of this strain was evaluated using a polyphasic approach. The strain produced light yellowish brown to dark brownish black substrate mycelium and greyish white aerial mycelium. The spiral spore chains were produced directly on aerial mycelium. CA1R205T was found to have ll-diaminopimelic acid in the cell peptidoglycan, galactose, glucose, mannose and ribose as whole-cell reducing sugars, MK-10(H4), MK-9(H6), MK-10(H2), MK-9(H4), MK-10(H6) and MK-10(H8) as menaquinones and iso-C15:0, anteiso-C15:0, iso-C16:0 and C16:0 as major fatty acids. Diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol were detected in the cells. These characteristics were consistent the typical chemotaxonomic properties of members the genus Streptomyces. The taxonomic affiliation at the genus level of this strain could be confirmed using its 16S rRNA gene sequence data. CA1R205T showed the highest 16S rRNA gene sequence similarity value to Streptomyces rapamycinicus NRRL B-5491T (98.9%), followed by Streptomyces iranensis HM 35T (98.8%). Digital DNA–DNA hybridization and average nucleotide identity-by blast (ANIb) values between CA1R205T and S. rapamycinicus NRRL B-5491T were 27.2 and 81.5%, respectively. The DNA G+C content of genomic DNA was 70.7 mol%. Due to the differences in physiological, biochemical and genotypic data, CA1R205T could be discriminated from its closest neighbour. Thus, CA1R205T should be recognized as representing a novel species of the genus Streptomyces, for which the name Streptomyces coffeae sp. nov. is proposed. The type strain is CA1R205T (=TBRC 11244T=NBRC 114295T). © 2021 The Authors.
