Abstract: This paper focuses on the research of the bioconversion of 1,3-propanediol by Klebsiella pneumoniae. The linear correlation of cell growth and 1,3-propanediol synthesis was found. An equation of the relationship between cell growth and biocatalysis was given.With the analysis of metabolism, it was discovered that the cell regulated the NADH production by cell growth in order to supply enough reductive equivalent for enzyme catalysis. A conclusion was drawn that the cell growth was coupled with the reactivation of a key-enzyme which catalyzes 1,3-propanediol production in Klebsiella pneumoniae.
