Isolation and identification of myxobacteria in the salinealkaline soils of Akesu in Xinjiang

Abstract:

Abstract:［Objective］ To isolate myxobacteria and investigate their diversity in saline-alkaline soils from Akesu in Xinjiang． ［Methods］Conventional culture-dependent methods，e． g． baiting technique，water agar，soil extract agar and mineral agar，were used to isolate myxobacteria from 25 soil samples collected from Akesu areas of Xinjiang． Combining with physicochemical properties (acidity /alkalinity，salt concentration，vegetation and geographical locations) of the soil samples，myxobacterial diversity was studied．［Results］In total 58 strains were isolated，and identified as belonging to 6 different genera，i． e． Myxococcus，Cystobacter，Corallococcus，Sorangium，Nannocystis and Polyangium of Myxococcales．The most frequent genus isolated was Myxococcus which may better adapt in harsh environments． Different myxobacterial diversity was detected in different habitat．［Conclusion］Myxobacteria diversity was low in saline-alkaline soils of Akesu in Xinjiang．
