摘要：

Micrococcus sp. (A.T.C.C. No. 407) grown in a synthetic medium produced large amounts of malic enzyme. Growth of the organism and the malic enzyme production by the cells was enhanced by the addition of NaHCO3 to the medium. CO2 fixation was catalysed by malic enzyme in cell free extracts. This enzymatic reaction required pyruvate, NADPH and Mg++. The radioactive product was identified by paper chromatography as malic acid. This evidence suggests that the physiological role of malic enzyme is in the maintenance of the tricarboxylic acid-cycle. © 1969.
