Applicant's summary and conclusion

Conclusions:
An extract of Floraesters IPJ was tested against five strains of Salmonella and E. coli at five concentrations in triplicates in the presence or absence of S9 enzyme activation system. The tests results indicate that the sample is not mutagenic to the test strains tested.
