反硝化菌功能基因及其分子生态学研究进展

由微生物推动的反硝化作用是地球氮素循环的重要分支,尽管已被发现广泛存在于细菌、真菌和古生菌中,其功能基因的研究仍仅限于很少几个物种。现代分子生物学的发展为研究环境微生物提供了行之有效的方法,以反硝化功能基因作为分子标记的分子生态学研究迅猛发展。综述近年来国内外微生物反硝化功能基因研究及以其为标记的分子生态学研究进展。

Advances in functional genes and molecular ecology in denitrifiers

Denitrification, a microbial process, is a major branch of the geography nitrogen cycle. Although the denitrifying ability has been widely found in bacteria, fungi and Archaea, the genes encoding the denitrifying reductases have been studied in few species. Modern molecular biology techniques provide effective methods to study the microbial ecosystem, and important knowledge has been accumulated on using functional genes for molecular techniques in the case of denitrification. Recent investigations on functional genes and molecular ecology in denitrifiers have been summarized.
