Embodiment 1

[0037] A gel-type enzyme formaldehyde-removing, deodorizing and deodorizing agent is prepared by the following method:

[0038] (1) Inoculate Issakuria orientalis into liquid medium A, culture and stand for 72 hours at 37°C to obtain Issakia orientalis culture medium, the total effective number of viable bacteria in the culture medium is 3.6×10 8 a / mL;

[0039] (2) Inoculate lactic acid bacteria paracasei into liquid medium A, shake and culture at 37°C for 36 hours, and the total effective number of viable bacteria in the culture medium for lactic acid bacteria paracasei is 2.3×10 8 a / mL;

[0040] (3) Inoculate Pediococcus pentosaceae in liquid medium B, shake and culture at 37°C for 48 hours to obtain Pediococcus pentosaceae culture solution, the total effective number of viable bacteria in the culture solution is 7.5×108 a / mL;

[0041] (4) Inoculate baker's yeast in liquid medium A, shake and culture at 37°C for 48 hours to obtain baker's yeast culture solution, the total ...

Embodiment 2

[0052] A gel-type enzyme formaldehyde-removing, deodorizing and deodorizing agent is prepared by the following method:

[0053] (1) Inoculate Issaccharomyces orientalis, Lactobacillus paracasei, Pediococcus pentosaceus and baker's yeast into the liquid medium according to the ratio of the number of bacteria 1:1:1:1, and culture it statically at 37°C to make the culture medium The total number of viable bacteria in the 9 cells / mL, the culture solution was centrifuged at 4°C and 3500rpm, and the supernatant was collected;

[0054] (2) Add the supernatant of step (1) to a dialysis membrane with a molecular weight cut-off of 14000, and put it into a phosphate buffer (9.46 g of disodium hydrogen phosphate in water, adjusted to pH 7.0 with potassium dihydrogen phosphate solution , fixed to 1L), dialyzed to remove low-molecular-weight substances at 5°C and magnetic stirrer stirring conditions, recovered the substances in the dialysis membrane, and obtained a liquid deodorizer;

Embodiment 3

[0062] Gas detection tube detection deodorization effect:

[0063] At room temperature, add 70ppm trimethylamine into a 1L brown glass bottle, and then spray 1ml of the liquid deodorizer prepared in Example 1 or 2 respectively. After 10 minutes, 1 hour, 3 hours, 5 hours, and 24 hours, extract 50ml of the gas in the container, and add an amine detection tube to detect the concentration of the amine gas. The culture medium not inoculated with microorganisms was used as the control group. Compared with the control group, the liquid deodorant obtained by the method of the present invention can completely digest and decompose trimethylamine within 1 hour, and has excellent deodorizing properties.

Abstract

The invention discloses a gel-type enzyme formaldehyde removing deodorant. The gel-type enzyme formaldehyde removing deodorant is prepared by mixing culture solutions of microorganisms including issatchenkia orientalis, lactobacillus paracasei, pediococcus pentosaceus and saccharomyces cerevisiae with sodium polyacrylate. According to the deodorant, various toxic and harmful substances existing in daily family life can be adsorbed, wrapped, decomposed and removed from a source of odor, the high deodorizing effect is achieved, and the degradation and removal rate on formaldehyde especially reaches 95% or above; the water content is 95%-99.5%, the natural evaporation capacity in 45 days is about 400 g, formaldehyde can be continuously decomposed, and the deodorant is suitable for formaldehyde deodorization in an environment where formaldehyde is continuously released for a long time.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a gel-type enzyme formaldehyde-removing, deodorizing and deodorizing agent as well as its preparation method and application. Background technique [0002] With the improvement of people's living standards in our country, the pollution of the environment by the emission of stench is increasing, and the pollution of the environment by the generated odor is intensifying, which poses a great threat to human health. Odor pollution is increasingly causing people attention. [0003] In our daily life, formaldehyde is the main pollutant in decoration and furniture. Its release period is as long as 3-15 years, and it will volatilize from the deep layer of the material when it meets heat and tide, seriously polluting the environment. Long-term exposure to the first dose of formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, leukemia and other diseases. Am...
