Abstract

The invention provides a biological deodorant and its preparation method and application. It is a biological fermentation liquid, and its microbial strains are composed of one or two types of yeast and one or two types of bacteria. Bacteria; Wherein, described saccharomycete comprises Candida antarctica, Candida rugosa, and described bacterium comprises Bacillus licheniformis, Bacillus subtilis, after microbial strain is domesticated with tea seed cake as the only nitrogen source, Two-stage fermentation process is used to ferment, and finally the microbial strains in the fermentation liquid are in a dormant state to obtain the final biological deodorant. When used, dilute with water and encounter air, the microbial strains can continue to grow and produce more enzymes . The biological deodorizer of the present invention can fundamentally remove the organic matter that produces peculiar smell, reduce or eliminate the degree of pipeline blockage due to biomass, and can also be used for cleaning oily or / and protein-containing or / and starch-containing dirt without damaging Any pipe fittings in the sewer, environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of biological deodorization, and in particular relates to a biological deodorant and its preparation method and application. Background technique [0002] In the existing biological deodorants, product inhibition occurs in most of the liquid fermentation systems, which greatly reduces the amount of enzymes that degrade odors produced by bacteria in the liquid fermentation systems, making the production cycle shorter In addition, people often scald the sewer with boiling water to clear the sewer and deodorize the sewer, but boiling water will denature the protein or starch and tightly adhere to the pipe wall, making it more difficult to remove. Doing this for a long time will make the sewer worse. Blockage and the taste is more difficult to remove, and the bad smell or peculiar smell has not been eliminated at all. The current biological deodorant mainly decomposes odorous substances. When the biological deo...
