| dc.description.abstract | Wine production is dependent on ethanol, but also on optimal glycerol concentrations, both of which are produced by S. cerevisiae fermentation. Wine characteristics like sweetness levels are influenced by glycerol concentrations. Additionally, elevated glycerol levels can be an indication of abnormal blood sugar levels. In both situations, close observations of glycerol levels are essential. One proposed method of measuring glycerol concentrations is through enzymatic oxidation with a glycerol biosensor. Alditol oxidase (AldO) is a recently discovered carbohydrate oxidase in S. coelicolor. Despite specificity for longer-chained polyols, studies have proposed that AldO can be used as a glycerol oxidase. Using random point mutations, an AldO mutant was isolated and had increased specificity for glycerol. These results suggest that potential for AldO with glycerol biosensor development. This project aimed to produce a glycerol specific alditol oxidase to be used as a biosensor. A synthetic alditol oxidase (AldOG) gene was used to produce AldOG via cloning methods. We plan to overexpress and purify the AldOG protein to use in construction of a glycerol biosensor in collaboration with Dr. Samuel Mugo (MacEwan University). | |
