The electronic structure of the primary electron donor D - 2A and other pigments in photosynthetic reaction center (RC) of the mutant HM202L of Rhodobacter sphaeroides has been studied with the ab initio DFT method.

The electronic structure of protein chains L and M in photosynthetic reaction center (PRC) of Rhodobacter sphaeroides (Van Niel) Imhoff, Truper et Pfennig) was studied by using the Overlapping Dimer Approximation method and the Extended Negative Factor Counter method at ab initio level.

The ultrafast energy transfer process, which takes place in femtosecond time range, in bacterial photosynthetic reaction center RS601 was investigated using femtosecond pump probe technique with selective excitation.

Research on VB_(12) wastewater treatment by using PSB-MBR;

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.
