Efficiency and microbial diversity of aeration solid-phase denitrification process bioaugmented with HN-AD bacteria for the treatment of low C/N wastewater

Distinctive Microbial Processes and Controlling Factors Related to Indirect N2O Emission from Agricultural and Urban Rivers in Taihu Watershed

“…In module V, SRB appeared to use sulfate as an electron shuttle to achieve organic matter degradation and nitrogen removal in cooperation with denitrifying bacteria, which would have reduced energy demand Desulfobulbus holds an extracellular electron transfer capacity and might participate in DIET between denitrifying bacteria (e.g., Dechloromonas and Sulfuritortus). , It was previously reported that Desulfobulbus and Dechloromonas were significantly cross-correlated in a wastewater treatment plant Desulfobacterium is an exoelectrogenic genus, while Dechloromonas has both denitrifying and electrogenic functions .…”

“…28,51 It was previously reported that Desulfobulbus and Dechloromonas were significantly cross-correlated in a wastewater treatment plant. 52 Desulfobacterium is an exoelectrogenic genus, while Dechloromonas has both denitrifying and electrogenic functions. 49 Therefore, the electrons released by electron donors could be transferred through DIET between Desulfobacterium and Dechloromonas.…”

Solving the problem of high concentration aniline inhibiting nitrogen removal: starting the SBBR with the prolonged aeration mode

“…The effect of prolonged aeration on microbial community structure in the SBBR was further explored. Rhodococcus (S0:8.66%, S1A:4.7%, S2A:14.9%), 34 Delftia (S0:0.07%, S1A:7.85%), 35 Leucobacter (S0:0.05%, S1A:2.25%), 36 norank-f-Anaerolineaceae (S0:0.62%, S1A: 1.31%), 37 Chryseolinea (S0:0.42%, S1A:1.35%) 38 and Pseudomonas (S0:0.22%, S1A:1.30%) 39 were functional bacteria of aniline degradation, which had good ability to degrade aniline. These bacteria maintained a high abundance, which explained the efficiency and stability of the system for aniline degradation.…”
