Cyanobacterial-type, heteropentameric, NAD+-reducing NiFe hydrogenase in the purple sulfur photosynthetic bacterium thiocapsa roseopersicina

Article Abstract:

Hydrogenases differ in electron carrier specifics in cellular localization, with some containing iron atoms while others are involved in energy conservation. The enzyme responsible for this activity was purified and a gene culture coding for cytoplasmic NAD+ reducing NiFe hydrogenase was identified and the physiological implications are discussed.

Optical characteristics of the phototroph Thiocapsa roseopersicina and implications for real-time monitoring of the bacteriochlorophyll concentration

Article Abstract:

The optical properties of the photosynthetic bacterium Thiocapsa roseopersicina at 800 to 930 nm could be used to monitor the concentrations of the bacterium in aquatic environments using remote sensing equipment. Other bacteria that contain bacteriochlorophyll could also be monitored remotely.

Identification of a diagnostic marker to detect freshwater cyanophages of filamentous cyanobacteria

Article Abstract:

The globally important photosynthetic microorganisms, cyanobacteria, are vulnerable to attack from the cyanophages virus. A study was conducted to develop a diagnostic probe that would detect freshwater cyanophages in natural water.
