Abstract
A novel actinobacterium, designated strain YIM 75704
, was isolated from a limestone quarry located at Gulbarga, Karnataka, India. The novel strain has showed typical morphological and chemotaxonomic characteristics of the family Streptomycetaceae. Comparison of 16S rRNA gene sequences indicated that this strain represents a novel member of the family Streptomycetaceae and exhibited 99.0% 16S rRNA gene sequence similarities with the type species of the recently described novel genus Allostreptomyces, that is, Allostreptomyces psammosilenae, whereas other species of Streptomyces were below 95% sequence similarity. The cell hydrolysates contained the LL-isomer of diaminopimelic acid and the predominant quinones were MK-9 (H
, H
and H
). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylinositolmannosides and three unknown phospholipids. The DNA G+C content was 75.0 mol%. A polyphasic study of the strain with morphological, phenotypic, phylogenetic and with DNA-DNA hybridization evidence with related members showed that this strain represents novel species of Allostreptomyces for which the name Allostreptomyces indica sp. nov., is proposed. The type strain is YIM 75704
(= DSM 41985
=CCTCC AA 209051
= NCIM 5485
).
