Abstract:

Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. The biomass produced in the reactors can potentially be used to produce biofuels and decrease some of the energy demands of the process. Wastewater treating photobioreactors are a relatively new technology and many aspects of their microbiology need further study. This thesis presents a broad overview of the algal and

This thesis Is an interdisciplinary study of microbial mediated extracellular electron transfer within contaminated subsurfaces. Geophysical, geochemical and microbiological techniques were used to Investigate microbial mediated electron transfer associated with a contaminated plume which was exhibiting a geoelectrical anomaly called a geobattery. Potentially electrogenic microorganisms were identified at the contaminated plume and were hypothesized to be involved in the generation of the geophysical signals defining the geobattery by contribution to large scale electron transfer.

In 1970 the Arrow oil spill off Cape Breton contaminated 305 kilometres of shoreline. Aerial and land surveys have demonstrated that natural weathering has occurred throughout this period, but it was relatively slow, especially in sheltered areas like Black Duck Cove lagoon.

Mineralization of hydrocarbon substrates (hexadecane, octacosane and naphthalene) indicated the presence of an active degradative microbial community, however, genes from known bacte

Changes in histamine, putrescine, and cadaverine concentrations in fresh and stored bluefish (Pomatomus saltatrix) were determined using a new HPLC method. The HPLC method utilized a 5.0% (w/v) trichloroacetic acid (TCA) extraction, pre-column fluorescamine derivitization, and fluorescence detection. The derivatives were stable over 24 h. The 5% TCA extraction produced percent recoveries of 98.6%, 98.7, and 100.0% for histamine, cadaverine, and putrescine respectively. The HPLC process including extraction, derivatization, and HPLC analyses was conducted in less than 45 minutes. F

Polymerase chain reaction (PCR) is a molecular technique which can be used to analyze the endodontic microflora and enable faster analytical progress. It is however uncertain if PCR can be used to predict treatment outcome in endodontic treatment. The aim of this

Abstract:

Effect of high hydrostatic pressure (150-200-250 MPa) on the microbial load and quality parameters (pH, color, 5-hydroxymethylfurfural-HMF) of white (Sultaniye) and red (Alicante Bouschet) grape juices with combination of temperature (20-30-40&deg<br>C) and holding time (5-10-15 min) was studied. Increased pressure and temperature showed significant effect on microbial reduction in white and red grape juices (p&lt<br>0.05). The effect of pressure and time on pH drop was found to be insignificant (p&gt<br>0.05). HHP resulted in E&lt<br>1 for white grape and E&lt<br>7 for red grape juice samples

Óleos essenciais podem ser usados para aumentar a atividade antimicrobiana. O objetivo do presente estudo foi avaliar o pH e atividade antimicrobiana/antibiofilme de medicações intracanal à base de hidróxido de cálcio (HC) associadas aos óleos essenciais, Lemongrass e Thyme, em comparação às associações com clorexidina (CLX) e paramonoclorofenol canforado (PMCC).
