Photosynthetic Bacteria

Photosynthetic or phototrophic bacteria (PTB) are some of the most widely distributed microorganisms in the environment, playing an important role in the food chain among all animals and plants. This genera of microbes receives solar energy with bacteriochlorophyll, which produce purple carotenoid pigments. Phototrophic bacteria, symbiotic nitrogen fixing organisms, also provide nutrients for animals and plants. They are capable of assimilating both carbon dioxide and molecular nitrogen, using light as an energy source. Photosynthetic bacteria are rich in amino acids, nucleic acids, hormones, coenzymes and vitamins that are produced within the cell.

Phototrophic bacteria are used widely in Asia for various biotechnological applications. PTB are currently being used for water purification, bioremediation of chemicals, bio-fertilizers, wastewater purifiers, animal feed and aquaculture supplements, biological hydrogen production and coenzyme Q production, etc. In addition, they are now being investigated in the solar industry for their uniquely efficient light harvesting complexes.

Direct Biologicals has a full line of phototrophic bacteria that range from single strains to complex hydrogen sulfide-oxidizing biosystems. As a result of extensive research, the company has successfully developed phototrophic communities that are effective for purifying the environment and generating nitrogen and carbon recycling.

Applications include:

  • Fruits and vegetables (improves yield, color, nutritional quality and storage time)
  • Plant and livestock pathogen protection
  • Livestock lagoons and wastewater purification
  • Bio-fertilizer
  • Compost activator
  • Pond, aquaculture and lake water purification
  • Yard and turf
