Embodiment Construction

[0013] A production method of microbial metabolite organic formaldehyde removal agent, comprising the following steps:

[0014] 1. Inoculate Streptococcus thermophilus, Candida paragusticum, and Lactobacillus plantarum into the sterilized medium for fermentation, respectively, and insert the seed solution of Streptococcus thermophilus and Lactobacillus plantarum at a ratio of 1% respectively Carry out anaerobic culture in anaerobic medium, the weight percent of this anaerobic medium raw material is, molasses: water: dipotassium hydrogen phosphate: yeast extract: soybean meal=35%: 60%: 0.1%: 0.4%: 4.5%, The Candida ruthenica seed liquid is inserted into the aerobic medium with a ratio of 1% for aerobic culture. The weight percentage of the raw material of the aerobic medium is water: molasses: urea: yeast extract = 60%: 35% :4.5% :0.5%;

[0015] 2. When the concentration of bacteria in each fermentation liquid reaches 10 6 / ml, mix the aerobic culture solution and anaerobic c...

Abstract

A production method for a microorganism metabolite organic formaldehyde removing agent comprises the steps that streptococcus thermophilus, candida utilis and lactobacillus plantarum are inoculated into an aerobic culture medium and an anaerobic culture medium to carry out fermentation respectively; when the cell concentration of all the fermentation solutions reaches 106 / ml, the aerobic culture bacterium solution, the anaerobic culture bacterium solution and a mixed culture medium are mixed at the proportion of 1:1:3, the mixture is poured into a fermentation bucket to carry out anaerobic fermentation for 20 days, and fermentation is ended when the pH value reaches around 7; fermentation metabolites are separated through a membrane separation technology, viable organism thalli are filtered out, and thus filter liquor containing the fermentation metabolites is obtained. According to the production method, three kinds of beneficial strains are screened according to the microecology principle, and reasonably matched and combined into multiple microorganisms for fermentation, and damage to the structure of the metabolites by high-temperature treatment is avoided through the combined fermentation technology and the membrane separation technology; meanwhile, the metabolism solution without the viable organisms has the good effects of formaldehyde removing, dust collecting, sterilizing and indoor air refreshing, and the product performance is more stable.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a method for producing an organic formaldehyde-removing agent for microbial metabolites. technical background [0002] Formaldehyde, also known as formaldehyde, is a colorless aqueous solution or gas with a pungent odor. It is often used as a raw material for the production of urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin in industrial production. binder. In addition, formaldehyde is also used as a raw material for household paints, construction adhesives, etc., and it contains different concentrations of formaldehyde in automobile exhaust and cigarette smoke. These formaldehydes that exist in people's living environment have a huge impact on people's health hazards. However, the aldehyde removal agents on the market usually use adsorbent as the main raw material, and the aldehyde removal effect is not ideal. Contents of the invention [0003]...
