- Abstract
The potential mutagenicity of protein-modified Enterococcus faecalis was evaluated by the Ames test. The test subject was designed with 0.05, 0.5, 5.0, and 50.0 mg/dish doses, and a control group was set. With Salmonella typhimurium mutant strains TA97, TA98, TA100 and TA102 as test strains, the Ames test was carried out with (+) or without (-) S9, and the number of revertant colonies was counted. The results showed that for the protein-modified E. faecalis in the case of + S9 and - S9, the average numbers of revertant colonies of the four test strains were less than two times of that of the negative control group, and no dose-response relationship was observed. The protein-modified E. faecalis was tested to be negative in the Ames test, indicating that the test substance was not mutagenic in vitro.
