Embodiment 1

[0031] Example 1 - Temperature tolerance test of different strains

[0032] Bacillus, mold and yeast strains isolated from chicken manure compost and from edible fungus waste chaff were inoculated into LB or PDA solid medium to test their tolerance to temperature, the results are shown in Table 1 .

[0033] Table 1 - Growth of strains at different temperatures

[0034]

[0035] Note: +++ grows well, ++ grows well, + can grow, - means no growth, -- means no investigation

[0036] From the test results in Table 1, it can be seen that yeast, Rhizopus microspora, Aspergillus oryzae and Aspergillus niger grow well at 37°C; It grows well at 45°C, but poorly above 50°C; Bacillus subtilis grows well at both 37°C and 45°C, but grows well at 50°C but slowly; Bacillus paralicheniformis grows well at 60°C and is relatively slow. And it can grow at 70 ℃; while Geobacillus thermophagus cannot grow below 45 ℃, it can grow at 50 ℃, and it grows well at 55-65 ℃, and it can also grow at 7...

Embodiment 2

[0038] Example 2 - Utilization test of carbon and nitrogen sources by different Bacillus species

[0039] The strains were inoculated into different carbon and nitrogen sources, respectively, to test their utilization of carbon and nitrogen sources. The results are shown in Tables 2 and 3.

[0040] Table 2 - Growth of strains in medium containing different nitrogen sources

[0041]

[0042]

[0043] Note: +++ grows well, ++ means good growth, + means able to grow, +- means almost no growth, - means no growth

[0044] Since the high-temperature decomposing function mainly depends on Bacillus, and the utilization of inorganic nitrogen sources and organic nitrogen sources will determine the emission of odors, it can be seen from the test results in Table 2 that these strains have certain differences in the utilization of nitrogen sources, which can It ensures that the different components of chicken manure compost are effectively degraded, and at the same time avoids growth ...

Embodiment 3

[0049] Example 3 - Effects of different strains on fermentation temperature rise

[0050] Different strains have different growth delay periods, and a short delay period can initiate the rapid progress of fermentation. The growth of Rhizopus microspora, Aspergillus oryzae, Aspergillus niger and Bacillus was observed by using bran culture based on 30 ℃ culture. The results are shown in Table 4.

[0051] Table 4 - Growth of strains at different times of strain culture

[0052]

[0053] From the results in Table 4, it can be seen that the surface of the bran of Rhizopus microspora was covered with mycelium and there were a lot of water droplets on the bottle wall for 20 hours, indicating that the strain was vigorously fermented, and the respiration produced a lot of heat, which was helpful for the temperature of the fermentation to increase. At the same time, it is also reflected on the side, but the easy agglomeration of too much Rhizopus microspora has a relatively adverse ...

Abstract

The invention relates to the technical field of micro-ecological preparations, and especially relates to a microecological preparation for chicken manure high-temperature decomposition and deodorization, and a preparation method thereof. The microecological preparation for chicken manure high-temperature decomposition deodorization is prepared from combined microbial powder, starch and auxiliary materials, and the combined microbial powder comprises bacillus, saccharomycetes and mould. The microecological preparation comprises saccharomycetes capable of promoting early-stage temperature rise, aspergillus capable of generating different functions of amylase, protease and lipase, and bacillus capable of tolerating high temperatures of different degrees. By decomposing protein and fat in chicken manure in the process of rapidly heating to a high temperature, the fermentation is synergistically promoted, the temperature rise is accelerated, the chicken manure is quickly decomposed, and the deodorization emission is reduced. The high-temperature strains with different tolerance degrees can ensure that the decomposition reaches enough high temperature and completion degree, and the effect of improving the composting quality is achieved.

Description

technical field [0001] The invention relates to the technical field of micro-ecological preparations, in particular to a micro-ecological preparation used for high-temperature decomposing and deodorizing chicken manure and a preparation method thereof. Background technique [0002] The rapid development of aquaculture, the improvement of intensification and the continuous expansion of production scale have produced a large amount of chicken manure that is difficult to handle. Direct use as plant fertilizer will cause root burning and death, and the parasite eggs, viruses and bacteria in it are harmful to the ecological environment. cause great harm. [0003] High temperature aerobic composting is one of the effective ways to deal with agricultural waste. At present, the decomposing treatment of chicken manure is mainly based on the traditional high-temperature stacking fermentation. However, due to the small number of functional microorganisms, the fermentation time is long...
