Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
In conclusion, it can be stated that during the described mutagenicity test and under the
experimental conditions reported, the test item did not induce gene mutations by base pair
changes or frameshifts in the genome of the strains used.
Therefore, AKIGALAWOOD is considered to be non-mutagenic in this Salmonella
typhimurium and Escherichia coli reverse mutation assay.
