Microalgae as a renewable source of energy –processing and biofuel production a short review

Abstract

The large application potential of micro-algae in the clean energy, biopharmaceutical and nutraceutical industries have recently drawn a substantial world interest. Biofuels, bioactive pharmaceutical drugs and food additives are organic, natural and economical sources. As biofuels, they have a good cost, renewability or environmental replacement for liquid fossil fuels. Microalges provide productive biomass feedstock for biofuel as demand for biofuels rises worldwide. These resources may be processed into biodiesel with ample supplies of biomass in rural communities. The cultivation of genetically modified algae in recent years has been pursued to promote the marketing of algae. In particular, this would benefit society if linked with a successful policy on algal biofuels and other by-products in the government. In terms of survival of the world's current problems, Algal technologies are a transformative but complementary tool. Algal fuel marketing remains a bottleneck and a threat. It is technically possible to have a big output but it is not economic. This study therefore focuses principally on problems in commercial development of biological microalgae and potential strategies for overcoming this challenge.
