Abstract

The invention discloses a deamination and deodorization bacterial strain QDN01 and an application thereof in biological deodorization. A deamination and deodorization bacterial strain is screened out from grass root black soil, and the biological characteristics and the denitrification condition on chicken manure of the bacterial strain are researched. By analysis of physio-biochemical characteristics and a 16SrDNA sequence, the deamination and deodorization bacterial strain is identified as enterobacter hormaechei, is named Enterobacter hormaechei QDN01, and is preserved in the China Center for Type Culture Collection in Wuhan University with the preservation number of CCTCC NO:M2013670. The research shows that the separated bacterial strain QDN01 is stably in biological characteristics, and fast in reproductive capacity, and particularly can quickly grow in the chicken manure to which starch is added, the increment is up to 250000000000cfu / ml, and meanwhile, a good denitrification and deodorization effect can be achieved. Compared with the prior art, the beamination and deodorization bacterial strain has obvious advantages. Therefore, a feasible and practical technical scheme is provided for innocent biological treatment of poultry manure, and the deamination and deodorization bacterial strain has a good development prospect.

Description

technical field [0001] The invention relates to a deammonization and deodorization bacterium, and also relates to the application of the strain in the harmless biological treatment of poultry manure and industrial waste water, especially in the deamination and deodorization of poultry manure. The invention belongs to the technical field of biological deodorization. Background technique [0002] With the rapid development of global industrial and agricultural products and the continuous improvement of human living standards, odors also come from the generated waste. Odor pollution is a kind of perceived pollution. Its harmful gases directly affect people's life and health. Therefore, odor pollution has been recognized as one of the six major public hazards after noise pollution. There are many ways to remove odor, and microbial odor removal has become one of the methods with high efficiency, environmental protection and low consumption, and has exerted great potential in env...
