Algal biotechnology
Algal biotechnology is defined as "the technical application of algae (including microalgae and macroalgae) or their derivatives to produce or change goods or processes for specific applications." The diversity of habitats in which algae can be found, as well as their morphological, physiological, and biochemical diversity, reflects their evolutionary diversity. Polysaccharides, carotenoids, phycobilin colours, and long-chain polyunsaturated fatty acids are only a few of the beneficial compounds found in algae. They are also used as fertilisers and growth stimulants in agriculture, as well as in wastewater treatment. Recently, algae, particularly microalgae, have sparked fresh interest as possible sources of renewable fuels. The pursuit of new products derived from new species, as well as new or enhanced applications, continues.
