Abstract:Due to the fact that most of the microbial species in nature can not be cultured, the traditional techniques base on cultivation and pure-culture isolation had become the major limitation to the study of microbial ecology. Advances in molecular biology provide resolutions to the questions that had hindered the microbiological study for a long time. Nucleic acid hybridization has great potentialities and has been widely applied in the field of systematic taxonomy and ecology of microbiology. Here we reviewed the basic principles of nucleic acid hybridization and its wide application, major advantages and limitations , and how to improve its detecting sensitivity and specificity. The applicative prospect of this technique was also discussed.
Keywords:nucleic acid hybridization  microbial ecology
