Microecologics removing formaldehyde and aromatic hydrocarbons in cars and preparation method of microecologics

The invention belongs to the technical field indoor air purification and particularly relates to microecologics removing formaldehyde and aromatic hydrocarbons in cars the a preparation method of the microecologics. The microecologics is prepared from, by weight, 3-5 parts of sphingomonas, 1-3 parts of lactobacillus casei, 1-3 parts of bifidobacterium breve, 1-3 parts of lactobacillus acidophilus, 40-80 parts of medium components, 30-40 parts of mycose, 10-20 parts of xylose, 80-100 parts of a plant extract and 2500-3000 parts of distilled water. Beneficial microorganisms of sphingomonas, lactobacillus casei, bifidobacterium breve, lactobacillus acidophilus and the like in the microecologics produce some active substances through auto-metabolism, volatile aromatic hydrocarbons of formaldehyde, benzene, xylene, phenol and the like in the air environment can be degraded, propagation of harmful bacteria in the environment is inhibited, and environmental air quality is improved; lasting effect is achieved, and th
