Daqu is usually used to make wine, which is the essence of China's wine making. In essence, the microorganisms growing in koji are mainly molds. Daqu is made because a large number of microorganisms and enzymes secreted by microorganisms (amylase, glucoamylase, protease, etc.) grow on it. ). Enzymes have biocatalysis, which can accelerate the conversion of starch and protein in cereals into sugars and amino acids. Sugar is decomposed into ethanol under the action of yeast enzyme, which is alcohol. Tillers also contain many such enzymes, which have saccharifying effect. The starch of tiller itself can be converted into sugar, and then converted into ethanol under the action of yeast. At the same time, koji itself contains starch and protein, which are also raw materials for brewing.

Comparatively speaking, there are more kinds of probiotics in the fermentation bed. Take Kangyuan Oasis as an example. For example, effective microorganisms are composed of about 80 kinds of microorganisms, and they are microbial preparations composed of more than 80 kinds of microorganisms belonging to the genus 10, mainly including photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes and so on.

The mechanism of action of em bacteria is to form the competition between em bacteria and pathogenic microorganisms for nutrition. Because EM bacteria are easy to survive and reproduce in the soil, they can quickly and stably occupy the ecological position in the soil and form a dominant community of beneficial microbial bacteria, thus controlling the reproduction of pathogenic microorganisms and attacking crops, which is the development direction of ecological agriculture at present and is more conducive to the sustainable development of agriculture.

Therefore, using probiotics such as auricularia auricula to make a fermentation bed can not only ferment feces and degrade most organic matter, but also form a beneficial microbial community, inhibit germs, contain lactic acid bacteria, and promote animal digestion.
