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...

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...

Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

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...

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...

Human bone is considered one of the most direct and insightful sources of information on peoples of the past. As a result, curation protocols have been developed to ensure that the integrity of human skeletal collections is maintained. Although collections are generally considered safe when these...
