CULTURE OF A PHOTO SYNTHETIC BACTERIA FROM THE MUD OF SHRIMP PONDS

A high productivity strain was screened from the mud of shrimp ponds,and was identified as Rhodopseudomonas palustris. The preliminary study on the growth conditions was carriedout. The tests showed the strain can grow anaerobically in light adopted to a large range of organic compounds. The optimun growth temperature is 25-30℃. The cells can grow under the light of 1 500-3 000 1x. Adding yeast extract can promote the cell growth. The optimun content of yeast extract in the culture medium is 0.15%. The strain adapt to 0.1-3% salinity.
