Abstract

An actinomycete strain, designated strain SH2-13^T, was isolated from a marine sediment sample collected from the Andaman Sea of Thailand. Applying a polyphasic approach, the isolate was identified as a member of the genus Micromonospora using morphological and chemotaxonomic characteristics, including the presence of meso-diaminopimelic acid in the peptidoglycan. Whole-cell sugars were arabinose, galactose, glucose, rhamnose, ribose and xylose. Diagnostic polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and phosphoglycolipids. The major menaquinones were MK-10(H2), MK-10(H4) and MK-10(H6). 16S rRNA gene sequence analysis revealed similarity to Micromonospora marina JSM1-1^T (99.1%), Micromonospora coxensis 2-30-b(28)^T (99.1%), Micromonospora aurantiaca DSM 43813^T (98.8%) and Micromonospora chalcea DSM 43026^T (98.7%). However, a combination of DNA-DNA hybridization results and phenotypic properties indicated that strain SH2-13^T (=NBRC 107934^T=BCC 45601^T) should be classified as the type strain of a novel species, with the proposed name Micromonospora sediminicola sp. nov. © 2013 IUMS.
