The present invention provides a method for screening the epsilon poly lysine producing strains, characterized in that, in addition the charge indicator medium according to the indicator and the epsilon poly lysine amino acid specific reaction formed by the transparent circle diameter or cluster size, screening of epsilon polylysine acid producing bacteria. The screening method of the invention not only can efficiently visually epsilon polylysine producing bacteria and other microbes to distinguish, but also can replace the cumbersome shake flask screening method, producing simple and intuitive screening of epsilon polylysine producing bacteria on plate. The invention has the advantages of simple process, small workload, short cycle and high screening efficiency.
