Embodiment 1Ba

[0037] Screening and Identification of Example 1 Bacillus coagulans Daoduo 4 (Bacillus coagulans Daoduo 4)

[0038] Formulated with CaCO 3 For the MRS solid plate of the emulsion, collect microbial samples from the wet soil, streak the sample on the above plate at 50°C, select the colony containing the calcium-dissolving circle, and repeatedly streak on the above plate to obtain a single strain .

[0039] Among them, MRS medium formula (1L): peptone 10g, beef extract 10g, yeast extract 5g, K 2 HPO 4 2g, triammonium citrate 2g, sodium acetate 5g, glucose 20g, Tween 80 1mL, MgSO 4 ·7H 2 O 0.5g, MnSO 4 4H 2 O 0.25g.

[0040] Send one of the screened strains to the Institute of Microbiology, Chinese Academy of Sciences for strain identification. According to the comprehensive analysis of the strain’s cell morphology, physiological and biochemical experiments, 16S rRNA gene sequence and other experimental data, refer to "Bergey's Handbook of Systematic Bacteriology" and Inte...

Embodiment 2

[0050] Embodiment 2 Deodorizing microorganism preparation and preparation method thereof

[0051] A deodorizing microbial preparation containing Bacillus coagulans Daoduo 4, which is fermented sour, with a pH value of 4 to 5, and the total number of effective viable bacteria ≥ 1.0×10 9 CFU / mL, of which, the main effective live bacteria Bacillus coagulans Daoduo 4 is 10 9 ~10 11 CFU / mL.

[0052] The preparation method of deodorizing microbial preparation is as follows:

[0053] (1) plate culture, using solid activation medium, plate activation of Bacillus coagulans Daoduo 4

[0054] Bacillus coagulans Daoduo 4 was inoculated on a solid activated medium plate by streak inoculation method, cultured at 50°C for 36-48 hours, and recovered to form a single colony.

[0055] The solid activation medium is prepared according to the following weight percentages: 1% peptone, 0.5% yeast powder, 1% sodium chloride, 2% agar, and the rest is distilled water, sterilized at 121° C. for 20 ...

Embodiment 3

[0066] Embodiment 3 Utilize above-mentioned microbial agent to carry out deodorization project in a landfill in Suzhou

[0067] Use the above-mentioned microbial preparations to prepare 500 kg of deodorant liquid at a ratio of 1:50.

[0068] In this example, gas samples were collected from the working surface of the domestic waste landfill, and the odor concentration and volatile organic compounds (VOC) were used as indicators to comprehensively reflect changes in environmental odor.

[0069] Odor concentration is an indicator that reflects people's subjective perception of odor, and it is measured by the three-point comparative smelly bag method, which is dimensionless. Ammonia is measured by solution absorption-spectrophotometry, VOC is measured by gas chromatography, and the units are mg / m 3 , from a quantitative point of view to reflect the change of the odor caused by the ambient gas.

[0070] The analysis methods for the content of volatile organic compounds (VOC) in s...

Abstract

The invention discloses a strain of bacillus coagulans (Bacillus coagulans) Daoduo 4 and a screening method thereof, and also discloses a microbial preparation containing the strain, a preparation method and an application of the microbial preparation. The microbial preparation of the present invention has simple cultivation, stable structure, non-toxic, harmless and no side effects, can effectively inhibit the reproduction and growth of spoilage bacteria, pathogenic bacteria and other harmful microorganisms, has strong stress resistance to the environment, has high temperature resistance, acid resistance, and Choline and other advantages can inhibit the growth of harmful bacteria in garbage, feces and sewage under complex conditions, eliminate odors, reduce pollution, and improve the environment. On the other hand, it can effectively remove volatile organic compounds (VOC), and it can be used in newly renovated houses and other places, which can significantly reduce the harm caused by decoration pollution to human health.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from a prior Chinese patent application with application number 2017101046947 filed on February 24, 2017, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to the technical field of environmental protection, in particular to a bacillus coagulans, a screening method thereof, a microbial preparation containing the bacillus coagulans, a preparation method and an application of the microbial preparation. Background technique [0004] With the rapid development of urbanization in our country, the level of urbanization has steadily increased, and the population has continued to increase, the environmental pollution caused by municipal solid waste has attracted people's attention. Domestic garbage accumulated at garbage collection points and garbage transfer stations causes problems such as odor emission, breeding...
