Community Structure and Microbial Activity of Sulfate Reducing Bacteria in Wastewater Biofilms and Mature Fine Tailings Analyzed by Microsensors and Molecular Biology TechniquesDownload
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;...
Microelectrodes can be used for profiling environmental biofilms. Currently there is no sulfate microelectrode available for studying sulfate reduction in biofilms. In this study, a sulfate microelectrode was fabricated and tested in measurement of environmental biofilms for the first time. The...
This research was conducted in a response to the dissolved oxygen (DO) decline in winter in the Athabasca River. Sediment oxygen demand (SOD) is considered as one of the major factors contributing to the DO decline in the Athabasca River. The SOD is influenced by physical phenomena, chemical...
Membrane aerated biofilms (MABs) have exhibited unique advantages over conventional biofilms for wastewater treatment. However, due to the limited available technology to probe the internal biofilms, the information for multiple microbial processes inside the MABs is quite inadequate. Microsensor...
