L-Carnitine can stimulate anaerobic growth of E.coli when exogenous electron acceptors (i.e. nitrate, etc.) are absent. During anaerobic growth, E.coli can reduce L-carnitine to γ-butyrobetaine by CoA-linked intermediates when carbon and nitrogen are present in the system. Therefore, L-carnitine may act as external electron acceptor for anaerobic growth as well as generation of an osmoprotectant for cell.
