【Abstract】 The paper described the structure, properties, usage,producing methods and breeding examples of L-leucine in brief, and discussed the biosynthesis pathway and metabolic regulation mechanism and biochemical characters of L-leucine producing strains. The authors mainly expounded the breeding strategies about how to obtain L-leucine high-producing strains by means of metabolic control, and ratiocinated the genetic marks which L-leucine high-producing strains possibly contained.更多还原
