The utilization of photosynthetic bacteria in human waste recycling systems is very popular nowadays, particularly because it has numerous advantages over algal systems that were previously used.
The strong metabolic power of photosynthetic bacteria in the conversion of plant materials and human waste into a valuable source of bio-gas is widely used.
Photosynthetic bacteria have created a new path of scientific discoveries, particularly in molecular elements and solar batteries. They are likely a natural photo-semiconductor because they can utilize solar (i.e. photon) particles in separating electromagnetic charges.
Recent scientific research indicates that photosynthetic bacteria could be a means of production of hydrogen using organic waste such as fluid wastes from pulp factories as feedstock.
Another noteworthy use of photosynthetic bacteria is in the disposal of toxic and hazardous waste in sanitary landfills and open dumping sites.
