Embodiment 1

[0029]Example 1, a microbial deodorant, which is composed of Bacillus halophilus LH-B.0015 and halophilic denitrifying bacteria YL5-2 with the preservation number CGMCC NO.16315. The two bacterial strains LH- The contents of B.0015 and YL5-2 in the microbial deodorant are 50% each. The deodorant is a pure bacterial agent.

Embodiment 2

[0030] Example 2, a microbial deodorant, the deodorant comprises Bacillus halophilus LH-B.0015 and the preservation number is CGMCC NO.16315 halophilic denitrifying bacteria YL5-2 composition, the two bacterial strains LH- B. The content ratio of 0015 to YL5-2 is 8:2, and the microbial deodorant also contains an appropriate amount of microbial additives, the additives are 5% glycerin solution, and the added amount is 10mg / L. The microbial deodorant can be applied to treat malodorous gas.

Embodiment 3

[0031] Embodiment 3, the deodorizing effect experiment of mixed microbial deodorant in different proportions

[0032] Pure strain fermented liquid obtained by the following method:

[0033] 1. Strain activation:

[0034] (1) Culture medium: glycerol 500mg / L, glucose 250mg / L, methanol 500mg / L, methylamine 200mg / L, sodium chloride 100-250g / L, phenol 100mg / L, aniline 50mg / L, sodium acetate 250mg / L L, trisodium citrate 250mg / L, yeast powder 100mg / L, peptone 200mg / L, beef extract 200mg / L, a small amount of trace elements, pH 7.5-8.0. The liquid medium is sterilized while controlling water evaporation. Add 2% agar powder to the solid medium.

[0035] (2) Strain activation: Inoculate the two pure strains into solid medium and activate them in a constant temperature incubator at 25°C.

[0036] 2. Preparation of high-concentration seed liquid: use an inoculation loop to take the activated strain and transfer it to a liquid medium, shake the flask at 10-35°C, 100-170rpm, and grow it...

Abstract

The invention discloses a microbial deodorant, which is prepared from halophilic fish bacillus LH-B.0015, and further prepared from halophilic denitrifying bacteria YL5-2 of which the preservation number is CGMCC (China General Microbiological Culture Collection Center) NO.16315. The microbial deodorant has the advantages that the microbial deodorant is prepared from the halophilic fish bacillus LH-B.0015; the invention further discloses application of the microbial deodorant. The microbial deodorant disclosed by the invention is remarkable in deodorization effect, can tolerate or degrade organic pollutants, and is particularly suitable for treating amine-containing odor and odor generated in a salt-containing environment. The microbial deodorant has the advantages of simple treatment process, stable effect, environmental poison impact resistance and salinity influence resistance, and has a very wide application prospect in foul gas pollution control.

Description

technical field [0001] The invention belongs to the field of environmental microbial deodorization, and in particular relates to a microbial deodorant comprising halophilic bacillus LH-B.0015 and halophilic denitrifying bacteria YL5-2 and an application thereof. Background technique [0002] Malodorous gas refers to volatile substances that can cause disgust or unpleasant odors in the human body, and is a kind of sensory (olfactory) pollution that is perceived by acting on the human olfactory organs through the air medium. In recent years, with the development of society, the improvement of people's living standards and the enhancement of people's awareness of environmental protection, people have put forward higher requirements for the quality of the air environment, and the lawsuits related to odor pollution have continued to increase, such as Nanjing, Jiujiang, Beihai, etc. There have been large-scale odor pollution incidents in the city that have seriously affected the l...
