The use of a biological procedure for L-carnitine production as an alternative to chemical methods must be accompanied by an efficient and highly productive reaction system. Continuous L-carnitine production from crotonobetaine was studied in a cell-recycle reactor with Escherichia coli

Two proteins, component I (CI) and component II (CII), catalyze the biotransformation of crotonobetaine to L(-)-carnitine in Proteus sp. CI was purified to electrophoretic homogeneity from cell-free extracts of Proteus sp. The N-terminal amino acid sequence of CI showed high

The biotransformation of crotonobetaine and D(+)-carnitine into L(-)-carnitine is affected by salt stress in the resting cells of E. coli O44 K74 and the transformed E. coli K38 pT7-5KE32. A yield of 65 and 80% of L(-)-carnitine, respectively, were obtained
