Respectively adding the high-efficiency oil stain cleaning agents prepared in the examples 1-6 and the comparative examples 1-3 into water to respectively prepare cleaning solutions with effective content of 15% as samples to be detected; and (5) evaluating the bacteriostatic effect.
The specific method comprises the following steps: a clean stainless steel table top is selected and divided into 10 areas with equal areas to serve as a preset oil stain table top. The 10 zones correspond to 10 test groups, examples 1-6 and comparative examples 1-3, respectively, and a control group, respectively. Before the experiment, the test sample was washed with a corresponding detergent, and the control group was washed with 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 a concentration of about 1 × 108~5×108cfu/ML. Then using a sample adding device to take 10 mu L of the bacterial suspension, inoculating the bacterial suspension to a corresponding cleaned table area, using a disposable sterile inoculating loop to coat the bacterial suspension into a circle, and then using a sterile plastic cup to seal the test area, so that the test area has a distance of 4mm-5mm with the edge of the test area;
after 12h post inoculation at room temperature, the inoculated sealed area was sampled. 1mL of phosphate buffer containing 0.1% AEO-9 (0.03mol/L) was carefully applied to the middle of the test area without touching the edges of the blocking area. At the same time, the coating solution was pipetted into a sterile test tube using a sterile micropipette. Each sample was plated, the sample to be tested was diluted 100-fold with Phosphate Buffered Saline (PBS) (0.03mol/L), 0.1mL was plated on a TSA plate containing 5% goat blood, a glass rod was spread, the plate was cultured in an incubator at 35. + -. 2 ℃ for 48. + -.4 h, and the number of colonies was counted.
The bacteriostatic rate (%) is (I-II)/I × 100%
Wherein, I is the average colony number of a control sample (sterile water); II is the average colony count of the test samples (the cleaning agent samples of examples 1 to 6 of the present invention and comparative examples 1 to 3). The result is an integer retained.
