Antimicrobial applications of treatments using light pulses emitted from light emitting diodes (LED)
DownloadSpring 2022
Low water activity (aw) foods have been associated with several foodborne outbreaks and recalls. Eradication of foodborne microorganisms like Salmonella and Escherichia coli from low aw foods is challenging, as they are resistant to conventional decontamination practices. High intensity light...

One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

Bacteria of the genus Lactobacillus can be found associated with plants, insects and vertebrate hosts, and their lifestyle can range from free-living to strictly host specific. Of the lactobacilli associated with vertebrates, the lifestyle of L. reuteri is particularly well understood. The...

The study of methanogenesis in wastewater biofilms and various aggregated methanogenic environmental samples with high spatial resolution can be achieved by using microbiosensor techniques. In this study, the fabrication of a microbiosensor for methane detection was studied. This microbiosensor...

Treatment of Oil Sands Process-affected Water (OSPW) Using Integrated Fixed-film Activated Sludge (IFAS) Reactors
DownloadFall 2016
The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands, is currently stored in tailings ponds due to its toxicity to the aquatic organisms. The primary toxic constituents of OSPW are a complex mixture of alicyclic and aliphatic compounds containing carboxyl...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...
