A method for assay of microbial tannase (tannin acyl hydrolase) based on the formation of chromogen between gallic acid and rhodanine is reported. Unlike the previous protocols, this method is sensitive up to gallic acid concentration of 5 nmol and has a precision of 1.7% (relative standard deviatio
