摘要：
There is disclosed a method for producing 3,4-dihydroxyphthalic acid, comprising treating phthalic acid with a product which is obtained by treating the cell membrane fraction of microorganism bacterial bodies capable of converting phthalic acid to 3,4-dihydroxyphthalic acid with a condensate of polyethylene oxide with a higher alcohol, thereby converting the phthalic acid to 3,4-dihydroxyphthalic acid. According to the method, only 3,4-dihydroxyphthalic acid, which is an intermediary metabolite, can be produced efficiently in a process of biodegrading phthalic acid with a microorganism.
