土壤是环境微生物学研究中最具挑战性的环境,也是生物分子、遗传资源开发的热点区域。在"宏-组学"方法快速发展的今天,土壤微生物分离培养技术在微生物环境功能研究、代谢途径的阐明、特定功能的验证及基础实验和生产实践的应用等方面仍然发挥着重要作用。本文首先分析了大多数环境微生物不能被分离培养的几个原因。然后重点综述了近年来在土壤微生物分离培养技术方面的探索,主要包括生长培养基的优化和重新设计如培养基稀释分离、添加生长限制因子、更换凝固剂等,在延长培养时间、改善含氧量、降低培养温度等方面对生长条件进行改进,采用"扩散盒"、"原位培养陷阱"等技术对微生物进行天然环境原...

Soil is probably the most challenging of all natural environments for microbiologists, and the hotspot for discovering of novel biomolecules and genetic resources. Cultivation of environmental microorganisms was ignored and marginalized in the tremendous progress of “meta-omics” technologies. Nevertheless, by cultivation-based approaches, researchers can acquire novel microorganisms that are undetected by molecular methods, be allowed for the verification and testing of hypotheses of metabolic potential and function of novel genes determined ...
