Embodiment 1

[0027] Mix the tylosin residue and wheat straw uniformly at a weight ratio of 2:1 to obtain a mixture, wherein the moisture content of the tylosin residue is 70% to 75%, and the moisture content of the wheat straw is 10% to 15%. The length of wheat straw is 1cm, and it is composted after mixing according to the above ratio. The moisture content of the mixture is kept at about 57%. The pile is not turned over for the first 3 days. ~70°C and keep it for 23 days, then lower the temperature to ferment, turn the compost once every two days, and ferment for a total of 35 days. After fermentation, the organic fertilizer is obtained by crushing and sieving, and the materials on the sieve are used as auxiliary materials for re-fermentation.

[0028] The gas generated during the mixing process of tylosin bacteria residue and auxiliary materials, the aerobic fermentation process and the pulverization and screening process is collected and passed to the waste gas treatment device for trea...

Embodiment 2

[0030] Mix the tylosin residue and corncob evenly in a weight ratio of 2:1 to obtain a mixture, wherein the moisture content of the tylosin residue is 70% to 75%, and the moisture content of the corncob is 10% to 15%. The length of the corn cob is 2cm, and it is composted after mixing according to the above ratio. The moisture content of the mixture is kept at about 60%, and the compost is not turned over for the first 3 days. ~70°C and keep the temperature down for 22 days to ferment, turn the compost once every two days, and ferment for a total of 35 days. After fermentation, the organic fertilizer is obtained by crushing and sieving, and the materials on the sieve are used as auxiliary materials for re-fermentation.

Embodiment 3

[0033] Mix the tylosin residue and corncob evenly in a weight ratio of 4:1 to obtain a mixture, wherein the moisture content of the tylosin residue is 70% to 75%, and the moisture content of the corncob is 10% to 15%. The length of the corn cob is 2cm, and it is composted after mixing according to the above ratio. The moisture content of the mixture is kept at about 65%. The compost is not turned over for the first 3 days. After the temperature rises to 55-60°C, the compost is turned over for fermentation. ~70°C and keep the temperature down for 21 days to ferment, turn the compost once every two days, and ferment for a total of 35 days. After fermentation, the organic fertilizer is obtained by crushing and sieving, and the materials on the sieve are used as auxiliary materials for re-fermentation.

Abstract

The invention relates to the technical field of microbial fermentation, in particular to a tylosin mushroom dreg compost fermentation process which comprises the following steps: mixing tylosin mushroom dregs with auxiliary materials, composting, carrying out aerobic fermentation, crushing after fermentation, and screening to obtain an organic fertilizer; the auxiliary material is corncob or wheat straw. The method disclosed by the invention can be used for efficiently removing residual tylosin in mushroom dregs and removing drug-resistant genes in thalli at the same time.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a composting fermentation process of tylosin bacteria residue. Background technique [0002] Tylosin is a broad-spectrum antibiotic widely used in livestock produced by Streptomyces. As a by-product of the fermentation process of tylosin, tylosin residue is mainly composed of mycelium, protein, fermentation waste and a small amount of incompletely extracted antibiotics. Residual antibiotics will exert selective pressure on bacteria in antibiotic residues, leading to the emergence of high-abundance drug-resistant bacteria and drug-resistant genes, resulting in serious environmental pollution. Exploring the technology to effectively remove antibiotics and drug-resistant genes from antibiotic residues to reduce the pressure of antibiotic resistance on the environment has become a research hotspot. [0003] The prevention and control of antibiotic resistance should b...
