biological stability of water-based metal cutting fluids in China In recent years, the biological stability of water-based metal cutting fluids has aroused widespread concern in the domestic industry, and domestic research has been conducted in this area

Bacteria (The spoilage water-based metal cutting fluid taken from the site, the total number of bacterial colonies after constant temperature culture >10 mL, true

The filter paper was cut into 1cm diameter round paper, soaked and drained in the tested bactericide, and then the paper was stuck in the center of the AGAR plate with inoculated bacteria, and cultured at 36℃ for 48h. If the fungicide has a bacteriostatic effect, there is no colony growth around the paper, so as to form a round transparent bacteriostatic circle

In general, liquid fertilizers need to be added in the production and storage process to prevent the growth of bacteria, mold and other microorganisms, thereby extending the validity of the fertilizer and ensuring fertilizer efficiency. In particular,

There are many kinds of sterilization preservatives, which can be divided into inorganic sterilization preservatives and organic sterilization preservatives according to the different molecular structures.

What is the difference between anti-mold and mildew agent? Mycotoxins already exist in raw materials. In order to avoid the harm of mycotoxins to animals, mildew removal agents are added to absorb and discharge mycotoxins. At present, the main anti-mildew agents are organic acids and their salts.

Preservatives are a kind of food additives that can inhibit microbial activity and prevent food spoilage. In order to make the food have a certain storage period, certain measures must be taken to prevent the infection

A preservative is a substance that prevents the growth of microorganisms in a product. The effect of preservatives on microorganisms can only
