Algae, considered as a biological substance, refers collectively to the biomass or biogenic material derived from photosynthetic, typically aquatic, non-vascular organisms encompassing microalgae (e.g., chlorophytes, diatoms, cyanobacteria in some usages) and macroalgae (seaweeds). This substance is characterized by high concentrations of pigments (such as chlorophylls, carotenoids, and phycobiliproteins), variable macromolecular composition (proteins, polysaccharides, lipids), and often substantial contents of structural or storage polysaccharides (e.g., starch, alginates, carrageenans). Algal biomass is studied as a feedstock for biorefinery applications, including biofuels, bioplastics, nutraceuticals, and as a source of specialized metabolites with defined biochemical and physicochemical properties.
An international team of researchers has uncovered a remarkable molecular trick used by a unique group of land plants, one that could eventually be engineered into crops like wheat and rice to dramatically boost how efficiently ...
