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.
目的
从新疆阿克苏的盐碱土中分离粘细菌并研究其多样性。
方法
采用传统的依赖培养的方法，如诱饵技术、水琼脂、土壤浸出液琼脂和矿物琼脂，从新疆阿克苏地区采集的25份土壤样品中分离粘细菌。结合土壤样品的理化性质（酸碱度、盐浓度、植被和地理位置），研究粘细菌的多样性。
结果
共分离出58株菌株，鉴定为属于粘球菌目6个不同的属，即粘球菌属、孢囊杆菌属、珊瑚球菌属、堆囊菌属、小囊菌属和多囊菌属。分离出的最常见属是粘球菌属，其可能更能适应恶劣环境。在不同生境中检测到不同的粘细菌多样性。
结论
新疆阿克苏盐碱土中的粘细菌多样性较低。
