A Primary Study on Biodiversity of Moderately Halophilic Actinomycetes in Xinjiang and Qinghai Area
|
Abstract:
Some soil and muddy samples were collected from areas of Xinjiang and Qinghai in the west of China. 8 and 32 moderately halophilic actinomycete strains were isolated respectively using Starch_Casein agar, Glycerol_Asparagine agar and Soil_extract agar media. Then 14 strains were chosen for 16S rDNA amplification and systematic analysis based on comparison results with their morphology, physiological characteristics and whole cell_wall amino acids analysis. There were at least 5 genera and more than 10 species of moderately halophilic actinomycetes recovered from Xinjiang and Qinghai from the view of biodiversity, Such as genus Nocardiopsis and genus Streptomonospora of the family Nocardiopsaceae , genus Prauserella and genus Saccharomonospora of the family Pseudonocardiaceae , genus Streptomyces of the family Streptomycetaceae . In addition, the variety from Xinjiang was much higher than from Qinghai area.
