Screening of amine dehydrogenase from bacteria, yeasts and molds was done. In this paper, we report on histamine dehydrogenase and benzylamine dehydrogenase. Screening of amine dehydrogenase was carried out following the replica method. Twenty-nine microorganisms were grown on histamine plates under aerobic conditions. Ten microorganisms were grown on histamine plates under anaerobic conditions. On the other hand, sixteen microorganisms and two microorganisms were grown on benzylamine plates under aerobic and anaerobic conditions, respectively. No molds were grown on benzylamine plates
