海洋环境中硫酸盐还原菌的快速测定方法研究

Rapid Detection Methods for Sulfate-reducing Bacteria in Marine Environments

硫酸盐还原菌(SRB)是腐蚀性最强,也是研究最广泛的腐蚀微生物,广泛存在于海洋环境中。SRB的状态与其参与的腐蚀过程密切相关,而SRB状态的快速测定仍是一大难题。SRB种群浓度和代谢活性的快速、准确测定,能够为揭示SRB在腐蚀过程中的作用机理,实现微生物腐蚀状态监测提供理论依据和指导。本文将简要介绍本课题组在SRB种群浓度和代谢活性检测的研究进展,阐述各类方法的优缺点、适用条件及检测性能,为后续SRB状态检测方法的发展及实用化提供参考。

Sulfate-reducing bacteria(SRB)are the most corrosive and the most extensively studied corrosion related microorganisms,they are widely distributed in various marine environments.Although it has been clearly known that the status of SRB is closely related with their roles in relevant corrosion processes,however the determination of the population concentration and metabolic activity of SRB is still a big problem in the present.The development of quick and accurate detection approach could provide theoretical basis and guidance for revealing the mechanism of SRB action in the corrosion process and monitoring of microbial influenced corrosion status.This paper briefly introduces the research progress of our research group in detection of the population concentration and metabolic activity of SRB,and elaborates their advantages and disadvantages,applicable conditions and detection performance,which may provide reference for the development and practical application of detection methods for the actual situation of SRB in marine environments in the future.
