J M Obón et al.
Applied microbiology and biotechnology, 51(6), 760-764 (1999-07-28)
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
K Eichler et al.
Molecular microbiology, 13(5), 775-786 (1994-09-01)
The sequence encompassing the cai genes of Escherichia coli, which encode the carnitine pathway, has been determined. Apart from the already identified caiB gene coding for the carnitine dehydratase, five additional open reading frames were identified. They belong to the

L(-)-carnitine was produced from D(+)-carnitine by resting cells of Escherichia coli O44 K74. Oxygen did not inhibit either the carnitine transport system or the enzymes involved in the biotransformation process. Aerobic conditions led to higher product yield than anaerobic conditions.
Manuel Cánovas et al.
Journal of basic microbiology, 43(4), 259-268 (2003-07-23)
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
