This article was too review the research progress in the production of gallic acid using microbial transformation method. Literatures on microbial transformation in gallic acid production were summarized

including material

mechanism

fermentation condition and production mode. Microbial transformation method has incomparable advantages over traditional alkali and acid catalysis methods in production of gallic acid. Research focusing on the breeding of strains with high conversion rate and the optimization of culture conditions laid the foundation for the further research in the improvement of the yield of gallic acid. Microbial transformation method was a good way to the development and application potential in gallic acid production.
