Feasibility Study on a Measurement Method and a Portable Measuring System to Estimate the Concentration of Cloxacillin and β-Lactamase in Milk

Figure 1

Schematic representation of the proposed measurement method. If no antibiotic is present, all the AmpC is linked to the CENTA (), thus hydrolyzing lactam rings. However, if some lactam antibiotic inhibitor of AmpC is present, some AmpC will link to it, thus reducing the hydrolysis of lactam rings, hence reducing the overall variation of the absorption spectra of the CENTA.
