Native Lipase

Lipase from<em> Candida rugosa</em> was immobilized onto four different types of activated carbon; KI/2030, KI/3040, KI/5060 and KI/6070. The immobilized lipase was used in the esterification of oleic acid and 1-butanol in hexane. The effects of difference pore sizes, surface area, reaction temperature, thermostability of the immobilized lipases, storage stability in organic solvent and leaching studies were investigated. Among the four samples, KI/6070 gave the highest activities and stability in all the parameters investigated. Immobilized lipases generally exhibit activities higher than the native lipase for the parameters studied, with optimum temperature of 40°C. Immobilized lipases are more stable than native lipase in hexane at room temperature up to 12 days. Leaching study proved that the immobilization of lipase using physical adsorption is cheap and easy. This method was found to be suitable for the attachment of enzyme on the support.

In this study, a portable and disposable paper-based microbial fuel cell (MFC) was fabricated. The MFC was powered by Rhodopseudomonas palustris bacteria (R. palustris). An activated carbon sheet-based anode pre-loaded organic matter (starch) and R. palustris was used. By using starch in the anode, R. palustris-loaded on the anode could be preserved for a long time in dry conditions. The MFC could generate electricity on-demand activated by adding water to the anode. The activated carbon sheet anode was treated by UV-ozone treatment to remove impurities and to improve its hydrophilicity before being loaded with R. palustris. The developed MFC could generate the maximum power density of 0.9 μW/cm2 and could be preserved for long-term usage with little performance degradation (10% after four weeks).
