The high-efficiency oil stain cleaning agents prepared in the examples 1-6 and the comparative examples 1-3 are respectively added into water to prepare cleaning agents with the effective content of 15% as samples to be tested; and (5) evaluating the antibacterial effect.
The specific method comprises the following steps: a clean stainless steel table top is selected and divided into 10 areas with equal area and is used as a preset oil stain table top. The 10 areas correspond to 10 test groups, examples 1-6 and comparative examples 1-3 and one control group, respectively. Before the experiment, cleaning is carried out by using the corresponding cleaning agents, and the control group is cleaned by using sterile water. Each group was washed 3 times at 30min intervals.
Continuously inoculating Staphylococcus aureus for 3 generations, and diluting the bacterial suspension to obtain bacterial suspension concentration of about 1×10 8 ~5×10 8 cfu/ML. Then using a sample injector to take 10 mu L of the bacterial suspension, inoculating the bacterial suspension to a corresponding cleaned table surface area, using a disposable sterile inoculating loop to coat the bacterial suspension into a circle, and then using a sterile plastic cup to seal an inspection area so that the distance between the bacterial suspension and the edge of the inspection area is 4mm-5 mm;
12h after room temperature inoculation, the inoculated sealing area was sampled. 1mL of a phosphate buffer containing 0.1% AEO-9 (0.03 mol/L) was carefully applied to the middle of the test zone without touching the edges of the closed zone. Simultaneously, the coating solution was aspirated into a sterile test tube with a sterile micropipette. Plating is carried out on each sample, the sample to be tested is diluted 100 times by Phosphate Buffer Solution (PBS) (0.03 mol/L), 0.1mL is inoculated on the surface of a TSA plate containing 5% of sheep blood, the plate is uniformly coated by a glass bent rod, and the plate is cultured in an incubator at the temperature of (35+/-2) DEG C for (48+/-4) h, and the colony number is counted.
Antibacterial ratio (%) = (I-II)/ix100%
Wherein I is the average colony count of a control sample (sterile water); II is the average colony count of test samples (cleaning agent samples of examples 1 to 6 and comparative examples 1 to 3 of the present invention). The result retains integers.
