Figure 5: Mass spectra of the intermediate products of E2 degradation by strain DSSKY-A-001. In the mass spectrum, the abscissa indicates the mass-to-charge ratio (/) value of the ion, and the value of the mass-to-charge ratio from left to right increases. The ordinate indicates the intensity of the ion current, usually expressed as relative intensity; i.e., the strongest ion current intensity is set to 100%, and the ratio of other ion peak intensities to it is relative abundance.
