水产养殖中好氧反硝化细菌的筛选及评价研究进展

Advances in Screening and Evaluation of Aerobic Denitrifying Bacteria in Aquaculture

高密度、集约化水产养殖中氨氮、亚硝酸盐等有害氮源大量积累,严重破坏水环境并损坏水产动物的健康,对水产养殖行业造成极大危害。好氧反硝化细菌可将有害无机氮还原为氮气溢出,有效改善水质,而菌种筛选是好氧反硝化细菌研究和应用中一个关键环节。本文对好氧反硝化细菌菌种的筛选、评价方法进行归纳、总结,从样品采集、培养基配制、培养方式及评价方法等方面探讨适合水产养殖的方法和标准,以期对水产中好氧反硝化菌种筛选和评价提供参考,并对未来的研究方向进行了展望。

High density farming techniques easily result in the accumulation of harmful nitrogen sources such as ammonia nitrogen and nitrite,which are highly toxic to water environments and cultured aquatic animals,and they do great harm to the aquaculture industry.However,aerobic denitrifying bacteria can use inorganic nitrogen and reduce it to these forms of reduced nitrate or reduce nitrogen,and then effectively improve water quality,and the strains screening is a key step in the research and application of aerobic denitrifying bacteria.In the review,we summarize the screening and evaluation methods for aerobic denitrifying bacteria,and discuss the methods and standards suitable for aquaculture through some aspects including sample collection,medium preparation,cultivation methods and evaluation methods.This paper will provide a reference for the screening and evaluation criteria for aerobic denitrifying bacteria in aquaculture,and make prospects for future research directions.
