| Abstract: | Objective To study biological effects of space flight on purple nonsulfur photosynthetic bacteria. Methods Two purple nonsulfur photosynthetic bacteria, Rhodopseudomonas palustris H3 and Rhodobacter sphaeroides ZGY, were carried on satellite for 15 days and some of their biological effects were studied after recovery. Results In space condition, survival rate of bacteria was promoted. The purification of organic wastewater, removal of nitrite,degradation of phenol and decolorization of acid red B were enhanced, and the resistance of both strains to medicine was stable. Conclusion The major morphological and physiological characteristics of loaded strains H3 S and ZGY S were not changed after space flight. |
