摘　　要：L-苹果酸是生物体内三羧酸循环的成员之一,在食品、医药、日用化工等部门具有广泛的用途。文中从限氧发酵、碳酸钙的添加量、乙醛酸循环和TCA循环相应酶的抑制剂几个方面初步探讨黄曲霉积累L-苹果酸的代谢机制,得出CO2固定途径是积累L-苹果酸的主要途径。L-malic acid is a member of tricarboxylic acid cycle （TCA cycle） in organism, which has widespread applications in food, medical, daily chemical industry, etc. The paper preliminary introduced the metabolic mechanism of L-malic acid in Aspergillus flavus from the aspects of limiting oxygen fermentation, the addition of calcium carbonate, the inhibitor of enzyme in the TCA cycle, glyoxylate cycle and so on. It was concluded that CO2 fixing pathway was the main route accumulating L-malic acid.
