Marine macroalgae are a diverse group of multicellular, plant‐like protists that can be classified into brown, green and red algae. All of them accumulate starch in the interior of their cells as energy store, and other different polysaccharides of large molecular chain. Marine plant biomass has many advantages over terrestrial plant biomass as a feedstock. Recent breakthroughs in converting diverse carbohydrates from seaweed biomass into liquid biofuels through metabolic engineering have demonstrated potential for seaweed biomass as a promising, although relatively unexplored, source for biofuels. They have also developed effective mechanisms to survive many biotic threats, like bacteria, virus, or fungal infections. Because they are sessile organisms, seaweeds have evolved to live in variable, extreme, and hostile abiotic environmental and stress conditions, like temperature changes, salinity, environmental pollutants, or UV radiation exposure. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The journals provide forum and motivates scientists, researchers, academics, engineers, and practitioners in all aspects to share their professional and academic knowledge in the fields computing, engineering, humanities, economics, social sciences, management, medical science, and related disciplines.
