A Lot of alkalophilic actinomycetes were isolated from alkaline soil samples collected at Yunnan, China using a number of different media adjusted to pH 10. Forty nine isolates and 10 type strains of the genus Streptomyces were selected for studying their physiological, biochemical, morphological and chemotaxonomic characteristics, and a cluster analysis based on their 82 unit characters was carried out. DNA-DNA homology among 9 strains selected from each cluster was determined. Characteristics of the alkalophilic actinomycetes and relationship between the alkalophilic and non-alkalophilic actinomycetes were discussed.
