Streptomyces actinomycinicus sp. nov., isolated from Thai peat swamp forest soil (original) (raw)

International journal of systematic and evolutionary microbiology, 2015

Abstract

A novel actinomycete strain RCU-197T was isolated from peat swamp forest soil collected from Rayong Province, Thailand. Based on polyphasic approach, the strain was classified in the genus Steptomyces. It contained LL-diaminopimelicacid in cell wall peptidoglycan. No diagnostic sugars was detected in whole cell hydrolysates and lack of mycolic acids. The major menaquinones were MK-9(H6) and MK-9(H8). The predominant cellular fatty acids were iso-C14:0, iso-C15:0, anteiso-C15:0 and iso-C16:0. The polar lipids profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylglycerol and phosphatidylinositol mannoside. On the basis of the phylogenetic analysis of 16S rRNA gene, the strain formed distinct clade within the genus Streptomyces and was closely related to Streptomyces echinatusNBRC 12763T (98.78% similarity). According to the polyphasic approach as well as DNA-DNA relatedness, the strain could be clearly differentiated from its closely...
