摘要: Abstract Two species of perennial grasses—Lolium perenne var. Top One (LPT) and Lolium respect (LPR)—and a microbial consortium composed two denitrifying polyphosphate-accumulating organisms (DPAOs)—strain Bacillus sp. MOE1 Microbacterium MOE2—were used to study the effect plant–microorganisms interaction on removing nutrients from eutrophic water. The grasses could greatly remove pollutants; LPT up 40% total nitrogen (TN) 87% TP in 20 days. Among grasses, is more efficient removal ammonium (NH4+-N), phosphorus, CODMn. Without combining with LPR, immobilized DPAOs than 73% 32% nitrogen, 81% nitrogen. Removal efficiency TN, NH4+-N enhanced after especially LPT. combination may prove be promising approach bioremediation o...
