盐地碱蓬内生中度嗜盐菌

植物内生菌已经成为我国微生物领域研究的热点之一1],对植物内生细菌的研究不仅丰富了内生菌的生理类群及数量,而且探索了内生菌与植物的相互关系;同时也发现了一些新分类地位的菌株。目前,关于植物内生极端微生物的研究较少,本刊2010年第2期刊登了崔春晓、夏志洁等发表的文章"盐地碱蓬内生中度嗜盐菌的分离与系统发育多样性分析"2],作者根据盐地碱蓬内生境高盐的特点,从中不仅

Suaeda salsa L. of endophytic moderately halophilic bacteria

Objective] In order to indicate the relationship between soil microbial quantity and soil factor. Methods] Selected 11 typical plots under different saline-alkali soils in Hexi Corridor in spring, the soil microbial quantity, the enzyme activity and the physicochemical properties were investigated and variance analyzed, simple correlation analyzed, stepwise regressive analyzed and principal component analyzed. Results] It shows that there were obvious differences between the primary saline-alkali soil, the secondary saline-alkali soil and farmland soil in soil physicochemical properties and soil microbial quantity. The soil microbial quantity was generally at a low level and at regularity: primary saline-alkali soil
