Embodiment 1
[0016] Weigh 0.05 g of Bacillus natto, add it to 200 ml of sterile water, shake well, dip it with a sterile cotton ball, and apply it on the surface of the mobile phone screen.
[0017] Contact the surface of the screen of the mobile phone (iPhone 6plus) in normal use with the surface of the beef extract peptone agar medium for 10 seconds, then remove the mobile phone, so that the surface of the mobile phone screen is out of contact with the surface of the beef extract peptone agar medium, and place the medium on After cultivating at 30 degrees Celsius for 48 hours, take pictures with a camera, figure 1 (a) is the result of microbial culture on the surface of the mobile phone screen in normal use. It can be seen that the bacterial flora is complex. The composition of beef extract peptone agar medium is tryptone 10 g / L, beef extract 0.3 g / L, sodium chloride 0.5 g / L, agar powder 1.5 g / L, and the pH value is 7.2.
[0018] After applying the Bacillus natto solution and then using...
Embodiment 2
[0020] Weigh 0.05 grams of Bacillus natto and 0.05 grams of inulin, mix them and add 200 milliliters of sterile water, shake well, and spray on the surface of the mobile phone screen after shaking well.
[0021] Contact the screen surface of the mobile phone (Huawei PLK-AL10) in normal use with the surface of the beef extract-peptone agar medium for 10 seconds, then remove the mobile phone, so that the screen surface of the mobile phone is out of contact with the surface of the beef extract-peptone agar medium, and the medium After cultivating at 30 degrees Celsius for 48 hours, take pictures with a camera, figure 2 (a) is the result of microbial culture on the surface of the mobile phone screen in normal use. It can be seen that the bacterial flora is complex.
[0022] Contact the screen surface of the mobile phone (Huawei PLK-AL10) after smeared with the mixture of Bacillus natto and inulin and use it normally for 4 hours with the surface of beef extract peptone agar medium...
Embodiment 3
[0024] Weigh 0.05g of lactic acid bacteria, add 200ml of sterile water, shake well, use a sterile cotton ball to dip it, and apply it on the surface of the mobile phone screen.
