Composite microbial deodorizing agent and preparation method and application thereof

[0023] A composite microbial deodorant agent is prepared from the following raw materials in parts by weight: 10 parts of Pseudomonas fluorescens powder, 36 parts of Lactobacillus rhamnosus powder, 1 part of Bacillus licheniformis powder, amino oligosaccharide 2 parts, 50 parts of cornstarch, 1 part of dipotassium hydrogen phosphate.

[0024] The total number of live bacteria in the compound microbial deodorant is no less than 2.0×10 10 cfu / mL.

[0025] The preparation method of the Pseudomonas fluorescens bacteria powder is as follows: draw 50 μL of the Pseudomonas fluorescens bacteria liquid from the preserved glycerol tube into 4 mL of sterilized test tube LB medium, and cultivate overnight in a shaker at 60°C ; From the LB medium in the test tube, insert the activated strain into a shake flask containing 100mL LB medium with an inoculum of 2%; continuously culture and ferment in a shaker at 50°C for 48h; centrifuge and collect the bacteria after the fermentation is complet

[0030] A composite microbial deodorant agent is prepared from the following raw materials in parts by weight: 30 parts of Pseudomonas fluorescens powder, 25 parts of Lactobacillus rhamnosus powder, 10 parts of Bacillus licheniformis powder, amino oligosaccharide 6 parts, 25 parts of cornstarch, 4 parts of dipotassium hydrogen phosphate.

[0031] The total number of live bacteria in the compound microbial deodorant is no less than 2.0×10 10 cfu / mL.

[0032] The preparation methods of the Pseudomonas fluorescens bacteria powder, Lactobacillus rhamnosus bacteria powder, and Bacillus licheniformis bacteria powder are all the same as in Example 1, and the preparation method of the composite microbial deodorant bacteria agent is the same as in Example 1.
