Pyrogallic acid,a widely used chemical raw material and reagent,was mostly prepared by the chemistry process of gallic acid decarboxylation.Since serious environment pollution and equipment corrosion with the above method,the article reviewed microbial strains and the related technology including mostly influence factors of yield,such as carbon sources,the concentration of substrate,pH and fermentation time from the perspective of microbial transformation.At the same time,related influence factors of the gallic acid decarboxylase (GAD) activity including pH,temperature,metal ions and additives were presented.Then,the article briefly introduced the treatment of wastewater made in the production process of gallotannin and other issues applying microorganism.Finally,some views and suggestions were put forward for the process for preparing pyrogallic acid with the new method in future,which would provide the guidance and reference for the industrial production of pyrogallic acid by microbial conversion.
