Demir January 2006, 96 pages The objective of this study is to perform morphine biotransformation by using phenol oxidases. Syctalidium thermophilum, Thermomyces lanuginosus and Phanerochaete chrysosporium cells and culture fluid were used as microbial intracellular and extracellular phenol oxidases. Besides the phenol oxidases produced in laboratory, commercial pure phenol oxidases, A.

Abstract:

Electrodialysis (ED) is an established technology used to transport small ions from one solution to another through an ion exchange (IE) membrane under the influence of an applied electric potential difference. This project aimed to develop a novel integrated bioreactor-ED system and to explore its application to a variety of bioprocesses including microbial fermentation and enzymatic bioconversion. A custom ED module was first designed and constructed that enabled the flexible configuration of different IE membranes. In order to establish the performance of the ED module for extraction of cha

Abstract:

Colon cancer is a complex and multifactorial disease and the colonic microbiota has been strongly implicated in its aetiology. The dynamic metabolic interaction between the colonic microbiota, dietary components and the colonic tissue are primary factors influencing the process of colon carcinogenesis. Human dietary habits strongly influence the development of sporadic colon cancer. However, characterising microbe-nutrient interactions and determining the effect of bacterial metabolic activity on colon cancer risk may help identify dietary components with potential cancer-preventing or promoti

Microbial leaching plays a significant role in the natural weathering of silicate containing ores such as diamond-bearing kimberlite. Harnessing microbial leaching processes to pre-treat mined kimberlite ores has been proposed as a means of improving diamond recovery efficiencies. The biomineralization of kimberlite is rarely studied. Therefore, this study investigated the feasibility of exploiting both chemolithotrophic and heterotrophic leaching processes to accelerate the weathering of kimberlite. Preliminary investigations using mixed chemolithotrophic leaching cultures were performed on f

Arsenic is highly abundant in the DTMF tailings and the principal environmental concern is the possibility for leaching of ferrihydrite-attached As into the surrounding environment.

Sclerotinia homoeocarpa (F.T. Bennett) is one of the most economically important pathogens on high amenity cool-season turfgrasses where it causes dollar spot.

To understand the genetic mechanisms of fungicide resistance, the whole genomes of two strains with varying resistance levels to fungicides, were sequenced. In unpublished data (Sang et al.), a RNA-sequencing analysis revealed three CYP450s that were validated to play a functional
