Increasing the extraction efficiency of algal lipid for biodiesel production: Novel application of algal viruses
AbstractVarious studies have been conducted recently using microalgal system for the production of algal lipid for biodiesel production. This study aimed at increasing the extraction efficiency of algal lipid from Chlorella sp. by the application of Chlorella viruses. The calorific value of lipid from Chlorella sp. has been reported to be higher than that of fresh water microalgae, making it a potential candidate to be used as biofuel. This is the first report on novel application of microalgal viruses for improving the extraction efficiency of algal lipid for biodiesel production through viral lysis of Chlorella vulgaris. The algal lipid extraction efficiency, increased by 11.68% in the case of Chlorella virus treated C. vulgaris when compared with Chlorella virus untreated C. vulgaris. The application of Chlorella virus and the viral encoded lytic enzymes for increasing the extraction efficiency of algal lipid will be helpful in optimizing algal biofuel industry in the future.
