Embodiment 1

[0022] When the present invention is concretely implemented, the preparation method of deodorizing Rhodococcus YKSW-6 bacterial agent comprises the following steps:

[0023] 1) Shake flask seed production: inoculate the YKSW-6 strain in the seed medium, and cultivate it to the logarithmic growth phase at 30°C and 180r / min;

[0024] 2) Fermentation culture: inoculate the seed solution obtained in step 1) into a large amount of culture fermentation medium according to the inoculation amount of 5%, the cultivation temperature is 30°C, the rotation speed is 180r / min, the initial pH is 7.2, and the cultivation time is 24h. After the fermentation is completed, the Microbial deodorant.

[0025] The deodorizing Rhodococcus YKSW-6 of the present invention is obtained by separating and screening from pig manure composting soil of a pig breeding factory in Zhongmou, Henan Province. It has high-efficiency and rapid degradation ability for high-concentration skatole, and can effectively de...

Abstract

The invention relates to Rhodococcus gordoniae YKSW-6 and application thereof, can effectively solve the problem of degradation of high-concentration skatole, and adopts the technical scheme that the classification name of the Rhodococcus gordoniae YKSW-6 is Rhodococcus gordoniae, the Rhodococcus gordoniae YKSW-6 is preserved in the China General Microbiological Culture Collection Center (CGMCC), the preservation number is CGMCC No. 22972, and the preservation number is CGMCC No. 22972. The Rhodococcus gordoniae YKSW-6 is preserved in Institute of Microbiology, Chinese Academy of Sciences, No.3, No.1 yard, West Beichen Road, Chaoyang District, Beijing, on July 28, 2021, has efficient and rapid degradation capability on high-concentration skatole, has a degradation rate of 93.6% on skatole in compost, has a remarkable deodorization effect, is an innovation on skatole degradation microorganisms, and has broad application prospects.Good application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a strain of Rhodococcus gordii YKSW-6 and its application. Background technique [0002] With the rapid development of large-scale and intensified livestock and poultry breeding, livestock and poultry production can meet the needs of residents for meat, eggs, and milk, and the environmental pollution caused by a large amount of excrement and stench is gradually becoming the focus of attention. . Accompanied by a large amount of excrement, the emission and discharge of odorous substances have adverse effects on livestock production, residents' health, and air quality. [0003] Odor substances emitted by livestock and poultry have complex components and various types. According to their chemical properties, odor substances emitted by livestock and poultry can be divided into four categories, namely volatile nitrogen-containing compounds, volatile sulfur-containing...
