摘要：

Denitrification by Alcaligenes eutrophus H16 is genetically linked to megaplasmid pHG1. Unexpectedly, the gene encoding the nitrite reductase (nirS) was identified on chromosomal DNA. The nirS product showed extensive homology with periplasmic nitrite reductases of the heme cd(1)-type. Disruption of nirS abolished nitrite-reducing ability, indicating that NirS is the enzyme essential for denitrification in A. eutrophus.
