摘要: A Gram-positive, nonmotile, moderately halophilic, alkali and thermotolerant strain designated DAS 165(T), was isolated from a dry land soil sample from the Gulbarga region, Karnataka province, India. The isolate produced yellow substrate mycelia and gray aerial mycelia on most tested media. Strain DAS 165T showed growth in the presence of 5 to 7% NaCl and at 45 degrees C. The DNA G + C content was 69.7%. 16S rRNA gene sequence analysis together with these characteristics consistently assigned strain DAS 165(T) to the genus Streptomyces. The 16S rRNA gene sequence analysis revealed that strain DAS 165(T) was most closely related to S. tendae ATCC 19812(T) (D 63873) with a sequence similarity of 99.6% (three nucleotide differences out of 1,517). Strain DAS 165(T) formed a distinct clade based on analysis of the almost complete sequence and 120-nucleotide variable gamma region of the 16S rRNA gene. Despite the high sequence similarity, strain DAS 165(T) was phenotypically different from S. tendae ATCC 19812(T). DNA-DNA hybridization between these strains was 47% showing that strain DAS 165(T) is a distinct genomic species. Phenetic and genetic results support the classification of strain DAS 165(T) as a new species, for which the name S. tritolerans is proposed, with strain DAS 165(T) as the type strain (=DSM 41899(T)= CCTCCAA 206013(T)).
