Distinct distribution pattern of abundance and diversity of aerobic anoxygenic phototrophic bacteria in the global ocean.
The results suggest that AAPB abundance and diversity follow opposite trends from oligotrophic to eutrophic regimes in the ocean, and the Indian Ocean contained relatively high AAPB% compared with the other two oceans, corresponding to the high primary production in this region. Expand
Biological Nitrogen Removal through Nitritation Coupled with Thiosulfate-Driven Denitritation
A novel biological nitrogen removal system based on nitritation coupled with thiosulfate-driven denitritation (Nitritation-TDD) was developed to achieve a high nitrogen removal rate and low sludge production and it was found that free nitrous acid could directly affect the denitritis activity.

Diel variations in frequency of dividing cells and abundance of aerobic anoxygenic phototrophic bacteria in a coral reef system of the South China Sea
Tidal current and light were the primary factors controlling the diel varia- tions of AAP bacteria in this area during the study period, and the frequency of dividing cells (FDC) of AAPacteria was significantly higher than total bacteria in the study area. Expand
Depth-Resolved Distribution of Particle-Attached and Free-Living Bacterial Communities in the Water Column of the New Britain Trench
This work investigated for the first time the variations of abundance and diversities of the PA and FL bacterial communities in the epi-, bathy-, and abyssopelagic zones of the New Britain Trench and found that the PA communities showed decreasing species richness but increasing relative abundance with depth, suggesting the increasing ecological significance of thePA bacteria in the deep ocean.

The hadal biosphere: Recent insights and new directions
Abstract The hadal zone is the deep ocean with depths exceeding 6000 m. With an area approximately equal to the size of Australia, but constituting the deepest 45% of the vertical depth of the globalExpand
An Exploratory Study on the Pathways of Cr (VI) Reduction in Sulfate-reducing Up-flow Anaerobic Sludge Bed (UASB) Reactor
Investigation of pathways for Cr (VI) removal under biological sulfate-reducing condition in the up-flow anaerobic sludge bed (UASB) reactor confirmed that sulfide was oxidized to elemental sulfur instead of sulfate during Cr ( VI) reduction. Expand
Investigation on thiosulfate-involved organics and nitrogen removal by a sulfur cycle-based biological wastewater treatment process.
Spiking organics significantly improved both denitratation and denitritation activities while minimizing sulfide inhibition of NO3(-) reduction during thiosulfate-based denitrification. Expand
Physicochemical and biological characterization of long-term operated sulfate reducing granular sludge in the SANI® process.
The present investigation sheds light on the physicochemical and biological characteristics of the SRB granulate, and provides valuable information for scaling-up the SANI(®) process to treat real saline sewage in Hong Kong. Expand
System evaluation and microbial analysis of a sulfur cycle-based wastewater treatment process for Co-treatment of simple wet flue gas desulfurization wastes with freshwater sewage.
Diverse denitrifying genera were identified in the bacterial community of anoxic up-flow sludge bed (AnUSB) sludge and the Thauera- and Thiobacillus-like species were the major taxa and well explained the successful operation of the lab-scale MD-SANI process. Expand
Roles of sulfite and internal recirculation on organic compound removal and the microbial community structure of a sulfur cycle-driven biological wastewater treatment process.
Light is shed on the understanding of the roles of sulfite and IR in organic compound removal performance and microbial community structures in BSR, which could be in turn beneficial to optimize the organic removal capacity of the sulfur bionconversion-concerning sewage treatment technology. Expand
