PURPOSE:To obtain, the titled compound useful for treating cardiopathy, etc., industrially and advantageously by producing L-carnitine from crotonobetaine in a reaction system containing limited nutriments and volume of oxygen using a microbial cell cultivated in a culture medium containing no crotonobetaine. CONSTITUTION:A microbial cell cultivated in a culture medium containing no crotonobetaine is used in a reaction system containing limited nutriments and volume of oxygen to produce L-carnitine from crotonobetaine. The microbial cell to be used is at least one selected from the group consisting of the genuses Escherichia, Enterobacter, Klebsiella, Aerobacter, Erwinia, Serratia, Proteus, Salmonella, Alcaligenes, Flavobacterium, Achromobacter, Bacillus, Agrobacterium, Azotobacter, Micrococcus, Corynebacterium, Staphylococcus, Pseudomonas, etc.
