The characterisation of actinomycetes isolated from diverse South African sources, with emphasis on the genus Kribbella

Includes abstract.Includes bibliographical references (p. 169-171).Actinomycetes were isolated from the leaves of indigenous plants, aquatic sediment and soil samples, using alternative isolation methods to select for actinomycetes belonging to the rarer genera. Thirty actinomycete strains belonging to the genera Gordonia, Kineococcus, Kribbella, Micromonospora, Nocardia and Streptomyces were selected for full characterisation. A polyphasic approach combining physiology, chemotaxonomy and phylogenetic analysis was used to characterise these isolates. A number of potentially novel strains belonging to the rarer genera were identified, including two Kineococcus and three Micromonospora strains. Two novel Kribbella species were isolated from soil samples and the species descriptions of Kribbella karoonensis Q41T and Kribbella swartbergensis HMC25T were published in 2006
