Seaweed is the common name for countless species of marine plants and algae that grow in the ocean as well as in rivers, lakes, and other water bodies. Commonly, it is categorized into three broad groups based on pigmentation or type, such as red, brown, and green seaweeds. The major utilization of these seaweeds as food and food ingredients is in Asia-Pacific, particularly in China, Indonesia, the Philippines, Korea, and Japan, where seaweed cultivation has developed into a huge industry. Currently, seaweeds are being extensively explored as a fuel because of their high photosynthetic efficiency and their ability to produce lipids, a biodiesel feedstock that is expected to open new avenues for seaweed biomass manufacturers.
