NewsResearchers develop new weapon against harmful algal blooms
Few studies have looked into how algal biomass, especially cyanobacteria, can be used to create materials that remove phosphate from water. Now, researchers have transformed cyanobacterial biomass, which is typically a hazardous waste, into custom-made adsorbent materials that can pull harmful phosphorus out of water.
