Is it true that the more hyphae grow in the middle of the fermentation bed, the better?

In the practice of raising pigs in a fermentation bed, microbial hyphae can often be observed in the middle layer of the fermentation bed, that is, less than 20 centimeters. Some users think that only the more hyphae grow, the better the effect of the fermentation bed. Farmers think that there is a natural reason for this: because the more hyphae, the more abundant microorganisms, the feces are transformed into microbial proteins. Pigs eat these hyphae, of course, save feed, and so on.

As the saying goes, "laymen watch the fun, experts watch the way." in the eyes of farmers, microbes are hyphae, which can be seen with the naked eye. However, in the eyes of microbial experts, this is not entirely the case, or: on the contrary, it is not that the more hyphae in the fermentation bed, the better, too much hyphae is a bad phenomenon, and it is a sign of the degradation of the function of the fermentation bed. It is the need to constantly replenish the cushion caused by the rapid decomposition of bedding, which increases the cost, and the function of decomposing feces is not the best.

There are many kinds of microorganisms. To put it simply, there are four commonly used categories, namely, bacteria, actinomycetes, yeasts, fungi, but only fungi, actinomycetes, and a small number of yeasts (such as Saccharomyces cerevisiae, Saccharomyces cerevisiae, Candida, etc.) really produce hyphae. But you can't say that bacteria and yeasts without mycelium are not bacterial proteins.

The strains in the fermentation medium of activity 99 contain fewer actinomycetes and fungi, so the fermentation bed made with activity 99 has relatively less hyphae, but the bacteria are abundant and the nutrients are easier to absorb (the fermentation bed will be more and more in the later stage of use, that is to say, the longer the use time, the mycelium in the fermentation bed will gradually increase, this is because of the accumulation in the process of long-term use, after all, the fermentation bed is mainly aerobic. The environment with little moisture is beneficial to the growth of fungi.

Although there is not much mycelium in the early stage, the function of the fermentation bed made by vitality 99 fermentation agent to decompose feces is more powerful, the smell of pig house is better, and the bacterial protein produced is more, better, which is more beneficial to the digestion and absorption of pigs.

Because the bacteria, yeasts and a small amount of actinomycetes are more dependent on bacteria, yeasts, and a small amount of actinomycetes to decompose faeces and produce bacterial proteins in vitality 99, while bacteria only produce colonies and do not produce visible hyphae. Among yeasts, only Saccharomyces cerevisiae, Saccharomyces cerevisiae, Candida albicans, etc., produce a little hyphae. At the same time, the albicans in activity 99 also produce some hyphae, and a small amount of actinomycetes also produce some hyphae. On the whole, the mycelium produced by the fermentation bed of activity 99 was not much.

But you can't say that bacteria are not bacterial proteins, but only visible hyphae are bacterial proteins. On the contrary, bacteria and yeasts have more advantages as proteins, and it is often these invisible bacteria and yeasts that are the best in bacterial proteins.

The protein content of bacteria is more than 60%, the protein content of yeast is more than 50%, and that of fungi (such as mold) is between 40% and 50%. Therefore, in terms of protein content, bacteria > yeast > fungi and actinomycetes.

In terms of bacterial wall thickness and texture, the cell walls of fungi and actinomycetes are the thickest and most difficult to digest, while bacteria are the thinnest, the permeability is the best and the digestibility is the easiest. Therefore, in terms of digestion and absorption, the digestion and absorption rate of bacterial protein is the best, so in terms of digestibility, the order is bacteria > yeast > fungi and actinomycetes.

In terms of protein quality, bacteria have the highest content of essential amino acids, such as lysine, methionine and tryptophan, followed by yeast, so the order of protein quality is still bacteria > yeast > fungi and actinomycetes.

From the point of view of the industrial production of bacterial protein at home and abroad, it is also mostly produced by bacteria and yeast, and it is rarely said that mold is used to produce bacterial protein.

Therefore, to sum up, which microbial cell protein is the best is clear at a glance. Fungi that do not produce visible hyphae have the best cell proteins.

The fermentation bed that produces a large amount of hyphae is not the best for decomposing faeces.

Why is that? Quite simply, such a fermentation bed lacks cooperation among microorganisms, and if the material layer is full of hyphae, it is a very domineering and exclusive way of growth. basically rule out the growth of other microorganisms (at least in this layer that produces dense hyphae), so there are only one or more bacteria (such as actinomycetes, fungi, etc.) that produce hyphae in this material layer. However, we know that microorganisms that decompose and assimilate feces are not the specialty of fungi, and the components of small molecules in feces such as ammonia nitrogen and uric acid are often the specialty of bacteria and, of course, actinomycetes. In the final analysis, this requires the division of labor and cooperation among various microorganisms, that is, to form a strong microecological balance environment, in order to most effectively decompose faeces and assimilate fecal components and produce the most bacterial proteins. For example, bacteria are mainly used to assimilate small molecular nutrients in feces and synthesize their own bacterial proteins. Fungal actinomycetes decompose a small amount of macromolecular substances (decomposing macromolecular substances such as starch, crude fiber and protein are the specialty of fungi) to produce a small amount of organic nutrition for bacteria to use. of course, in the aerobic state, it can also assimilate some fecal components, and the role of yeast is in the middle level. That is, the main secretion of growth factors, such as special vitamins, purine pyrimidine, etc., to supply the needs of bacterial growth, promote the reproduction and growth of bacteria, at the same time, yeast itself also has a strong function of assimilating small molecules in feces.
