Abstract: S-adenosyl-L-methionine(SAM)is a type of active amino acid having broad market prospects,and there have been manyreports on SAM production catalyzed by microorganisms. This paper integrated advances in genetic modification and fermentation optimizationof SAM-producing strain. From the points of elevating expression and activity of SAM synthetase,optimizing feeding mode of glycerol andmethanol,improving the generation of ATP and supplement policy of L-methionine,and blocking downstream metabolic pathway,themultiple strategies of enhancing SAM synthesis and accumulation and their mechanisms had been reviewed. Furthermore,on the basis of theauthors’ research practice,some new prospects on SAM biosynthesis by microbes were discussed.
