Phototrophic biofilms occur on surfaces exposed to light in a range of terrestrial and aquatic environments. Oxygenic phototrophs like diatoms, green algae, and cyanobacteria are the major primary producers that generate energy and reduce carbon dioxide, providing the system with organic substrates and oxygen. Photosynthesis fuels processes and conversions in the total biofilm community, including the metabolism of heterotrophic organisms. A matrix of polymeric substances secreted by phototrophs and heterotrophs enhances the attachment of the biofilm community. This review discusses the actual and potential applications of phototrophic biofilms in wastewater treatment, bioremediation, fish-feed production, biohydrogen production, and soil improvement.
光合生物膜出现在一系列陆地和水生环境中暴露于光的表面。像硅藻、绿藻和蓝细菌这样的产氧光合生物是主要的初级生产者，它们产生能量并还原二氧化碳，为系统提供有机底物和氧气。光合作用为整个生物膜群落中的过程和转化提供能量，包括异养生物的代谢。光合生物和异养生物分泌的聚合物基质增强了生物膜群落的附着。本文综述了光合生物膜在废水处理、生物修复、鱼饲料生产、生物制氢和土壤改良等方面的实际和潜在应用。
