Abstract excerpt
The mutant strain AN70 (ubiE) of Escherichia coli which is known to lack ubiquinone (Young IG et al. 1971), was analyzed for menaquinone (MK) and demethylmenaquinone (DMK) contents. In contrast to the wild-type, strain AN70 contained only DMK, but no MK. The mutant strain was able to grow with fumarate, trimethylamine N-oxide (TMAO) and dimethylsulfoxide (DMSO), but not with nitrate as electron acceptor. The...
