盐碱土壤放线菌的资源分布、新物种资源及分离方法研究概况

盐碱土壤放线菌抗逆能力强,是一种存在于高盐高碱区域中的极端微生物,其特殊的生理机制和代谢产物的多样性广受各领域的关注。为了更有效地挖掘盐碱土壤放线菌资源及其功能基因,充分了解盐碱土壤放线菌物种的多样性,选择最适分离方法至关重要。笔者综述了中国盐碱土壤放线菌的地理分布和资源多样性,统计并总结2000—2021年盐碱土壤放线菌新物种的情况,整理归纳盐碱土壤放线菌的主要分离筛选方法,并对之后的研究工作提出展望。

Resource Distribution,New Species and Isolation Methods of Actinobacteria in Saline-alkali Soil

Saline-alkali soil actinomycetes are highly resistant to stress. They are extremophiles that exist in high-salt and high-alkali areas. Their special physiological mechanisms and diversified metabolites have attracted wide attention in various fields. To effectively study the resources of actinomycetes in saline-alkali soil and their functional genes, it is important to fully understand the diversity of actinomycetes’ species in saline-alkali soil, and then choose the most suitable isolation method. This article summarized the geographical distribution and resource diversity of actinomycetes in saline-alkali soil in China, counted the new species of actinomycetes in saline-alkali soil from 2000 to 2021, summed up the main isolation and screening methods of actinomycetes in saline-alkali soil, and put forward a prospect for the future research work.
