In the fermentation process of organic fertilizer, the bacteria required are bacteria, fungi, actinomycetes, etc. What are the functions and differences of these microbial agents?

Among them:
Bacteria – quickly absorb soluble and easily decomposed organic matter, and play a major role in the temperature rise of fermentation.
Actinomycetes – decompose cellulose, dissolve lignin, the ability to decompose cellulose is not as good as that of fungi, but it is more resistant to high temperature and pH than fungi, and it is the dominant bacteria to decompose cellulose lignin during high temperature period. And can produce some antibiotics, inhibit the growth of some harmful bacteria.
Fungi–decompose lignin, cellulose. The optimum growth temperature is 25~30℃, which produces spores and is not easy to be killed.
In compost, the total number of bacteria > the total number of actinomycetes > the total number of fungi
