Solution：

Settlement generally measured by the following process:

1.During normal production, place two to three empty dried sterile dishes next to the normal cloth dishes.

2.Exposure and monitoring sediment with the same time (0.5-4 hours) removed.

3.Take a certain volume of deionized water V empty dish.

4.Take V1 rinse liquid through the liquid phase to obtain concentration C, each cloth point average concentration.

5.Get the amount of dust settling in each dish M = CV in mg / dish

According to the different deposition points of dust and different varieties of antibiotics, through the gradient experiment to determine the amount of enzyme in the medium.

General high performance liquid chromatography, or the use of analytical balance weighing method for determination.
