Algae are the diverse and potential organisms for the future economy

Algae is a group of ancient photosynthetic organisms ranging from prokaryotic cyanobacteria to eukaryotic microalgae. Algae are broadly classified as micro and macroalgae based on size. Macroalgae indicates large aquatic photosynthetic plants and microalgae are unicellular photosynthetic microorganisms. Algae represent a largely untapped resource among the biomass producing sectors of the world bio economy. The algae convert the nutrients into protein which can in turn to be feed the farm animals as a replacement to less sustainable soya protein. Algae are considered as clean renewable energy source as they do not cause pollution to the ecosystem. Biofuels,currently produced through algal biomass are bioethanol, biomethanol, biobutanol, biodeisel, biomethane, biohydrogen and bio-oil .
