Sulfate reducing bacteria (SRB) play a significant role in complex microbial environments such as wastewater biofilms and mature fine tailings (MFT). A unique characteristic of these complex microbial environments is that stratified structure containing both oxic and anoxic zones could be formed;...

Cryptosporidium, a waterborne protozoan pathogen that can cause gastrointestinal illness, is often found in surface waters that are used to supply drinking water. Filtration is a major barrier against Cryptosporidium in drinking water treatment processes. However, interactions between oocysts and...

Source-diverted greywater contributes to 60-70 % of conventional wastewater in volume and has a low organic matter concentration as compared to conventional wastewater. Greywater constitutes a high concentration of surfactants that are toxic in nature for the microbial community, which poses a...
