  • a Cells were grown in LAS medium supplemented with 7 mM choline.

  • b Toluene-treated cells and cells disrupted by passage through a French press were used for CDH and BADH assays, respectively. See Materials and Methods for details. Data are the means of results from duplicate assays with two independent cultures (standard deviations never exceeded 9%).
