Micromonospora tulbaghiae sp. nov., isolated from the leaves of wild garlic, Tulbaghia violacea (original) (raw)

INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2009

Abstract

A novel actinomycete, strain TVU1T, was isolated from leaves of the indigenous South African plant Tulbaghia violacea. Applying a polyphasic approach, the isolate was identified as a member of the genus Micromonospora. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain TVU1T was most closely related to Micromonospora echinospora DSM 43816T. However, phylogenetic analysis based on gyrB gene sequences showed that strain TVU1T was most closely related to the type strains of Micromonospora aurantiaca and Micromonospora chalcea. DNA–DNA relatedness values between strain TVU1T and the type strains of M. echinospora, M. aurantiaca and M. chalcea were 7.6±4.5, 45.9±2.0 and 60.9±4.5 %, respectively. Strain TVU1T could be distinguished from the type strains of all three of these species by several physiological characteristics, such as colony colour, NaCl tolerance, growth temperature range and sole carbon source utilization pattern. Strain TVU1T (=DSM 45142T=NRRL B-24576T...
