Embodiment Construction

[0137] The present invention will be described in detail below in conjunction with preferred embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0138] In this embodiment, the detection of the fungal killing effect of the 13α-(N,N-dimethylamino)ethylaminomatrine disinfectant solution sample with a concentration of 120 g / L is taken as an example for illustration.

[0139] The specific evaluation method is carried out according to the following steps:

[0140] (1) Sample extraction and minimum effective concentration determination

[0141] 1.1 Control sample: use Cha's culture medium as the control sample.

[0142] 1.2 Test samples: Randomly select 1 liquid disinfectant sample in the smallest sales package from 1 complete transport package of a production batch number for neutralizer identification and quantitative suspen...

Abstract

The invention relates to a method for evaluating the fungus killing effect of a liquid disinfectant. The evaluation steps include: sample extraction and determination of the minimum effective concentration; The live bacteria content of bacterial suspension after staining C B Blood count and inoculum C B Calibration; lgC B ‑ Relative fluorescence intensity log value lgI B Standard song establishment; neutralizer identification and quantitative suspension test; recovery solution I B Determination and its live bacteria content C B and T B Calculation; Calculation of killing rate R and sterilization index A; Judgment of results; The special feature is: the use of ATP fluorescence photometer to accurately and quantitatively evaluate the fungal killing effect of disinfectants characterized by R or A. The present invention stipulates to reclaim the test sample liquid and the control sample liquid after the different time of action, measure its I B and with lgI B Characterize and calculate R or A; provide the basis for judging the results. ATP bioluminescent IgC for the evaluation of the fungal killing effect of the disinfectant developed by the present invention B ‑lgI B The standard music method can improve the relevant evaluation method system of disinfection effect.

Description

technical field [0001] The invention relates to a method for evaluating the fungicidal effect of a liquid disinfectant, in particular to an ATP method for accurately quantitatively testing the fungicidal effect of a liquid disinfectant characterized by a killing rate R or a sterilization index A using an ATP fluorescence photometer. bioluminescent lgC B -lgI B The standard curve method belongs to the technical field of disinfectant sterilization effect evaluation. Background technique [0002] With the improvement of people's living standards and the enhancement of health awareness, in order to cut off the transmission of infectious diseases, liquid disinfectants such as peroxides, aldehydes, phenols, and quaternary ammonium salts are widely used in medical treatment, food, education, catering, and home use. The field of application is becoming more and more extensive, and the killing effect and broad-spectrum requirements for pathogenic microorganisms such as bacteria, fu...
