Here, the above-mentioned effective microorganism group refers to a variety of useful microorganisms included in the soil and conducive to the growth of plants. The group of photosynthetic bacteria, lactic acid bacteria, yeast and Actinomycetes (放 線 菌群) can be classified into.

First, the photosynthetic bacteria group is an autotrophic microorganism that synthesizes nitrogen compounds, amino acids, bioactive substances and sugars while eating light and heat as energy sources and ingesting harmful gases such as organic substances and harmful hydrogen.

Metabolites synthesized by the photosynthetic bacteria group not only help the growth of plants, but also can be used for breeding of other microorganisms, so that other effective microorganisms increase with the above-mentioned photosynthetic bacteria group.

Next, the lactic acid bacteria group synthesizes the lactic acid with sugars received from photosynthetic bacteria and yeasts to be described later, the lactic acid has a strong bactericidal power, and inhibits the degradation of harmful microorganisms and the rapid decay of organic matter.

Lactic acid bacteria facilitate the decomposition of hardly decomposable organic substances such as lignin and cellulose, and also play an important role in preventing various harmful effects caused by undecomposed organic substances and fermenting and decomposing organic substances.

In addition, the yeast is used to ferment other secretions such as lactic acid bacteria and actinomycetes, such as lactic acid bacteria and actinomycetes, such as lactic acid discharge from the roots of crops, amino acids emitted from photosynthetic bacteria, sugars or organic matter in the soil to the useful material for crops do.

Next, actinomycetes are intermediates between bacteria and fungi, which take amino acids produced by photosynthetic bacteria to produce antibiotics, thereby inhibiting pathogens or preoccupying substances necessary for the proliferation of harmful fungi or bacteria (chitin). It acts as a deterrent and creates a good environment for other microorganisms.

Actinomycetes coexist with photosynthetic bacteria and thus double the bactericidal action in the case of mixing with photosynthetic bacteria.
