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...
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...
We report on a reticulated filament found in modern and fossil cave samples that cannot be correlated to any known microorganism or organism part. These filaments were found in moist environments in five limestone caves (four in New Mexico, U.S.A., one in Tabasco, Mexico), and a basalt lava tube...
Treatment of Oil Sands Process-affected Water (OSPW) Using Integrated Fixed-film Activated Sludge (IFAS) ReactorsDownload
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...
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...
Many spring deposits throughout the world are characterized by spectacular deposits of calcium carbonate that are formed of various combinations of aragonite and calcite, and in very rare cases vaterite. The factors that control the precipitation of the aragonite and calcite have been the subject...
Modern travertine precipitation at Lýsuhóll hot springs, Snæfellnes, Iceland: implications for calcite crystal growth.Download
Three thermal springs, at Lýsuhóll on Snæfellnes Peninsula on the west coast of Iceland, with vent water temperatures of 20 to 46°C are characterized by thriving microbial mats that mediate the precipitation of opal-A, Fe-rich opal-A, Fe-rich reticulate coatings, and calcite that are intermixed...
Ichnology concerns the study of interactions between organisms and both soft and hard substrates. Actualistic observation of a modern day river channel molluscan assemblage including unionid and sphaeriid bivalves and gastropods within the Saint John River, Fredericton, New Brunswick, Canada...
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...
