Biological nitrogen removal from wastewater by denitrification of mix-culturing fungi and bacteria
混合培养真菌和细菌对废水的生物去氮作用

Denitrificationis a biological processin which nitrateand/or nitrite is reduced to gaseous nitrogen,dinitrogen(N2)or nitrous oxide(N2O)while carbon dioxide is thesecond gaseous product of the process.This is one of themain mechanisms of the global nitrogen cycle,and playsanimportant role as the reverse reaction of nitrogen fixa-tion in maintaining global environmental homeostasis1].Denitrification has beenlongthought to be a unique char-acteristic of prokaryotes2,3].Anumber of bacteria(suchasPseudomonas s...
