Recent advances in bioenergy production from Dairyindustrys algal

The use of algal for bioenergy production is expected to play an important role in securing energy supply inthe next decades.Major challenges of the modern world: energy security, oil price, resources depletion and climate change,have prompted significant advances in research and development of biomass-derived energy and fuels.Effective biogas production from Dairyindustry necessitates harvest at times of peak quality of biomass andlow-loss preservation for year-around supply.Algal bioenergys are seen as one of the most promising solutions of global energy crisis and climate changefor the years to come. Major advantages of algae are potentially high yield and no competition with foodcrops for arable land and fresh water resource. This review summarises recent advances in algal bioenergy production and focuses on synthesis of transportation fuel rather than characterising algal Dairyindustrys or their well-documented potential as bioenergy resource. The available literature covering production of bioethanol, biodiesel and other potential fuels are evaluated. Overall finding from this study suggests that to date the most effective methods of producing bioenergys from algal Dairyindustrys are: fermentation of microalgae to bioethanol and production of biodiesel via in situ transesterification of microalgal biomass. The realbreakthrough however is expected from metabolic engineering of photosynthetic organisms to produceand secrete bioenergys that promises significant simplification of down-stream processing.
