                             After enzymatic catalyzed reaction of tetracycline (Tet), it is necessary to enrich the remaining Tet before any further test. Working with our Advisor Cheng Hu, we successfully established a solid-phase extraction (SPE) method using SupelTM –Select SPE (Sigma-Aldrich). This work shall to some extend, if not definitely, provide some guidance for future teams.

                             We conducted an online survey concerning with antibiotic residues and resistance. We got more 1,200 responses, which provided sufficient data for us to analyze the knowledge and opinions of the public.

Many of them should impressing interests and enthusiasm in these topics.
