Purified purple non-sulfur bacteria 01S strain was separated and fostered from activated sludge of brewery wastewater and used to treat high concentrated organic brewery wastewater.

The primary researches on the amount distributions and groups of purple non-sulfur bacteria in estuary sludge of Xinyang Shihe river were carried out.

In order to improve the treatment efficiency of PSB, a strain of purple non-sulfur bacteria with high capacity of degradation was isolated and screened from nat.

Identification and phylogenetic analysis of an okenone-containing halophilic purple sulfur bacterium;

The effect of carbon and nitrogen sources on the accumulation of Poly-β-Hydroxybutyrate (PHB) by purple non-sulfur photosynthetic bacteria(PNSB)was investigated.

We use its pure culture treating the farm wastewater and the shrimp culture pond,testing the elimination of COD and NH_3-NO_2~-,the results showed that the purple non-sulfur photosynthetic bacteria can decompose the pollutants of the bottom mud effectively,eliminate COD and NH_3-NO_2~-from the water,reduced the COD value of the fish pond water to 20.

Two embedding carries of sodium alginate and polyvinyl alcohol were used to immobilize the purple non-sulfur photosynthetic bacteria.

Glutaric dialdehyde affect dehydrogenase activity of purple nonsulfur photosynthetic bacteria;

Some properties of native and immobilised cells of purple nonsulfur photosynthetic bacteria (PSB) were studied and compared under the condition of magnetic field.
