Description
beta-lactamase is a type of enzyme secreted by drug-resistant bacteria against beta-lactams antibiotics. Combining with beta-lactam ring, the beta-lactam ring is cleaved and destroyed and losing its antibacterial activity. which is is the main reason of resistant for the medicine of this type bacteria. Using the principle that beta-lactamase can decompose beta-lactam antibiotics, the content of beta-lactam antibiotics remaining after the reaction with beta-lactamase can be quickly determined, thereby indirectly detecting the residual beta-lactamase in pure milk, and then determine whether beta-lactam antibiotics have been added to the sample
