| Abstract: |
| Ames Salmonella TA97, TA98, TA100, TA102 and E.coli PQ37 were treated in vacuum and irradiation environment using a space combined low energy irradiation test equipment developed by Beijing Institute of Spacecraft Environmental Engineering. The influence of vacuum and irradiation environment in spaceships on microbe was studied. Back mutation test (Ames test) and SOS chromotest test were carried out on salmonella to evaluate the mutation effect of vacuum and irradiation environment in spaceships. The results of both SOS chromotest and Ames test indicated that spaceship environment can induce mutations and has certain effect on physiological metabolism of microbe. |
