EXAMPLE 1 isolation, screening and identification of Strain N-BA-9
1. Isolation and screening of Strain N-BA-9
45ml of distilled water is taken in a 250ml triangular flask, a certain amount of glass beads are added, sterilization is carried out for 20min at 121 ℃, and cooling is carried out to room temperature. Weighing 5g of preserved soil sample, adding into sterile water, crushing and mixing in a constant temperature shaking table at 30deg.C and 180r/min for 1-2h to free bacteria, transferring 10ml of mud-water mixture into 90ml of basic culture medium, adding n-butyric acid into the basic culture medium, and culturing and enriching at 30deg.C and 180 r/min.
Diluting enriched and domesticated bacteria liquid with sterile water to obtain 10 -1 ~10 -6 Gradient of different concentrations, 10 -4 、10 -5 、10 -6 Three gradients of bacteria-containing water of 0.1ml are coated on a selective culture medium flat plate, then the culture is carried out in an inverted incubator at a constant temperature of 30 ℃ for 2-5 d, the further separation and purification are carried out by using a flat plate dilution separation method, the purified strains are subjected to classification numbering, and the strains are stored on a bevel at 4 ℃ for standby.
2. Identification of Strain N-BA-9
After pure culture on LB medium, single colony and bacterial form of N-BA-9 strain are observed, and FIG. 1 shows single colony form of strain N-BA-9 growing on LB medium after streak culture for 48 hr; FIG. 2 shows the morphology of the single colony of strain N-BA-9 as observed by a microscope (10X 100). Colony is small round, white, neat in edge and smooth in surface. The thallus is ellipsoidal and does not produce spores.
The results of physiological and biochemical detection show that the N-BA-9 strain is a gram-positive strain, hydrolase and catalase are positive, and methyl red, indole and oxidase are negative in reaction.
The characteristic sequence of the strain is shown in a sequence table SEQ ID NO. 1 through molecular biological identification of ITS1-5.8S-ITS 2.
EXAMPLE 2 Effect of Strain N-BA-9 on degradation of pig farm malodorous substance N-butyric acid
1. Preparation of pig manure water
Mixing 20 g fresh pig manure and 80g clean water uniformly to prepare fresh pig manure water with a solid content of about 5%, and placing the fresh pig manure water in a 37 ℃ incubator for standing fermentation for 2 days to obtain pig manure water with a ozone degree M.OU of 6.233.
Degradation of the N-BA-9 bacterial suspension of the odor substance n-butyric acid in the pig manure water
5ml of N-BA-9 strain fermentation broth was inoculated into the above 100ml of pig manure water, the pH of the pig manure water was 7.2, the C/N was 31.4, the mixture was uniformly mixed, and after standing and culturing in an incubator at 30℃for 24 hours, the ozone degree M.OU of the pig manure water was measured, and the measurement value was 2.604, as shown in FIG. 4.
Calculation of degradation Rate of N-BA-9 Strain on odor substances in pig manure Water
FIG. 3 shows the detection value of the ozone degree M.OU in the pig manure water without inoculating the strain N-BA-9, wherein the degradation rate of the odor substances in the pig manure water by the strain N-BA-9 is [ (6.233-2.604)/6.233 ] ×100% = 58.22%.
4. Description of growth conditions of bacterial strain N-BA-9 in pig manure
The growth condition of the N-BA-9 strain in the pig manure water is evaluated by microscopic observation and OD measurement, and is comprehensively evaluated by adopting 10-point scoring, wherein the comprehensive score of the growth condition of the N-BA-9 strain in the pig manure water is 6 points. The result shows that the N-BA-9 strain has higher growth speed in fecal sewage, stronger reproductive capacity and better degradation capacity on N-butyric acid.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
