13C-NMR analysis of supernatants from metabolism of methanol plus acetate by M. barkeri Δmtr. Supernatants from cell suspension assays were examined by 13C NMR as described. Spectrum A, cell suspension assay buffer with unlabeled methanol and acetate. Spectrum B, cell suspension supernatant from nongrowing Δmtr cells incubated in the presence of methanol plus [1-13C]acetate. Spectrum C, cell suspension supernatant from nongrowing Δmtr cells incubated in the presence of methanol plus [2-13C]acetate.
