Problems solved by technology

The current countermeasure is to clean the screen of the mobile phone. The main method is to use liquid crystal screen cleaner made of chemicals or wipe it directly with alcohol (Chinese patent 201510721261.7), although this method can temporarily remove bacteria and stains on the mobile phone screen , but the downside is that the effect is short-lived and may cause superbugs and fungicide-resistant bacteria, and may also damage the phone or make scratches on the phone screen clearer

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.

Abstract

The invention discloses a method for improving surface floras of a mobile phone screen. According to the method, probiotics and/or prebiotics are used as a functional component, the functional component can be one or more probiotics, or one or more prebiotics, or a probiotic and prebiotic mixture. The components in the functional component can be mixed in any proportion, and the functional component can be dispersed on the surface of the mobile phone screen by spraying or smearing. The method can directly or indirectly change the composition of the surface floras of the mobile phone screen, effectively improves the microbial ecology of the surface of the mobile phone screen, reduces the number of pathogenic bacteria on the surface of the mobile phone screen, and realizes the effective cleaning of the mobile phone screen.

Description

technical field [0001] The invention relates to a method for improving bacterial flora on the screen surface of a mobile phone, belonging to the field of microbial ecology. Background technique [0002] Mobile phones are essential electronic devices in daily life, with a large number of users, high frequency of use, and various places of use. After investigation, it was found that the amount and type of bacteria on the mobile phone screen were different (Journal of Microbiology & Biology Education, 13, 59-61, 2012). The mobile phone screen is the place where people have the most contact with the surface of the human body when using a mobile phone, so the mobile phone screen is likely to become a transmission route for pathogenic bacteria. The current countermeasure is to clean the screen of the mobile phone. The main method is to use liquid crystal screen cleaner made of chemicals or wipe it directly with alcohol (Chinese patent 201510721261.7), although this method can tem...
