Streptomyces pharetrae sp. nov., isolated from soil from the semi-arid Karoo region

An actinomycete, strain CZA14 T , was isolated from Worcester in the Western Cape province of South Africa. Based on rapid genus identification, 16S-rDNA sequence similarities and chemotaxonomy, strain CZA14 T was identified as a member of the genus Streptomyces . It exhibited weak antibiosis against Bacillus coagulans ATCC 7050 T , Mycobacterium aurum A+ and Acinetobacter calcoaceticus C91. The results of physiological tests and analysis of the 16S-rDNA sequence allowed for the differentiation of strain CZA14 T from other species of the genus Streptomyces . Strain CZA14 T therefore represents a new species for which the name Streptomyces pharetrae is proposed, with the type strain CZA14 T (=DSM 41856 T =NRRL 24333 T ).
