Diversity of culturable actinobacteria from Qinghai-Tibet plateau, China.
To investigate the diversity of culturable actinobacteria and further screen for microbial pharmaceutics, seven different media were chosen to isolate actinobacteria from 87 soil samples collected from Qinghai-Tibet plateau. A total of 1930 strains was isolated and identified to belong to 11 suborders, i.e., Actinopolysporineae, Corynebacterineae, Frankineae, Glycomycineae, Kineosporiineae, Micrococcineae, Micromonosporineae, Propionibacterineae, Pseudonocardineae, Streptomycineae and Streptosporangineae, and 16 families, i.e., Nocardioidaceae, Actinopolysporaceae, Actinosynnemataceae, Dermacoccaceae, Geodermatophilaceae, Glycomycetaceae, Kineosporiaceae, Microbacteriaceae, Micromonosporaceae, Nocardiaceae, Promicromonosporaceae, Propionibacteriaceae, Pseudonocardiaceae, Streptomycetaceae, Streptosporangiaceae and Thermomonosporaceae. A primary taxonomic study showed that at least 22 genera of actinobacteria were identified from the soil samples, among which ten isolates represented hitherto unknown species. The results showed that there was abundant actinobacterial species diversity in the soil samples from the Qinghai-Tibet plateau.
