Abstract: | 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. |
