You can make organic safe crops!

What kind of microorganism is "Bacillus subtilis"?

The ever-increasing number of nature's excellent "Decomposers".

"Growing ability" and "the ability to decompose organic matter" are extremely active, "Bacillus subtilis" will increase more and more as long as the number of microorganism in the soil is secured above the certain level.

There are many "Bacillus subtilis" in the natural world, such as baked grass, rice straw, fallen leaves, compost, etc. in the field.There is more than 20% moisture.
 There is enough oxygen.
The temperature is in the range of about 20 to 50 ° C.
There is organic matter to become the nutrition source.

When these conditions are satisfied, it will actively multiply at an early rate of doubling from 40 minutes to 50 minutes while decomposing the organic matter. This proliferative power is to be noted in naturally occurring microorganisms that are being elucidated.

When it deviates from this environmental condition of 1 to 4, it forms hard spores of shell, it becomes dormant, and it has ability to withstand large environmental changes such as high temperature near 100 ° C, low temperature below freezing, ultraviolet light. As this bacterium grows, the organic matter as a nutrient source decomposes other microorganisms and pathogenic bacteria, so it can improve the intestinal flora of livestock and poultry, sterilize harmful microorganisms in the soil, water quality. It is used for improvement materials and others.


  • Action of metabolite (emission)

Bacillus subtilis breaks down nutrients and emits large amounts of metabolites. This metabolite contains substances of superior functionality as known for "Natto".


  1. Is "Bacillus subtilis" safe?
  • Bacillus subtilis Natto is also known as "Bacillus subtilis", which is also called Bacillus Natto bacteria.

Thread-pulling type generic name is simply called Bacillus subtilis Natto, and it is all Bacillus subtilis in terms of classification. The so-called type of bacillus subtilis Natto is said to be weak in Bacillus subtilis. When producing Natto with common Bacillus subtilis, decomposition progresses too much, and the original form of beans is said that the flavor will also drop without leaving.

  • Strong microorganisms attacking bad bacteria

"Bacillus subtilis" has no pathogenicity to humans and animals. Organic substances as nutrients are used for improving intestinal bacteria in animals and for sterilizing harmful microorganisms in soil, because they also decompose other microorganisms and pathogenic bacteria. In addition, university research found out that it has the effect of killing pathogenic Escherichia coli O - 157 and Salmonella.
Bacillus subtilis has extremely strong proliferative power, deprives other living places of living things, secretes antibiotic active lipopeptide and substances showing strong interfacial activity, and these substances suppress harmful bacteria. It is clarified in the resource laboratory of the Tokyo Industrial University. It is also used as a treatment for skin diseases and environmentally friendly microbial pesticides.


  1. How is "Bacillus subtilis" useful in soil that grows crops?
  • "Bacillus subtilis" for countermeasures against injury by continuous cropping

The causes of injury by continuous cropping are largely divided into three.
 Degradation of chemical properties (Salt accumulation, Acidification of soil, Trace element deficiency such as Mineral).
 Diseases caused by harmful microorganisms (Mold) in soil.
Injury due to nematodes.
Suppress growth of mold by the action of "Bacillus subtilis", to alleviate injury by continuous cropping
The most frequent microorganisums in the field are mold companions. Molds have digestive enzymes that decompose cellulose and are able to decompose plant residues, so molds dominate in fields where plant residues are to be embedded. Molds are capable of penetrating cells of plants by melting the defense wall made of cellulose of plants, which may cause injury by continuous cropping.
By the action of "Bacillus subtilis", it suppresses the growth of harmful microorganisms in the soil. Especially the effect of inhibiting growth of filamentous bacteria is great, suppressing the growth of mold etc. It is effective in alleviating injury by continuous cropping.
"Bacillus subtilis" that increases the natural enemy of "Nematode" which is the cause of injury by continuous cropping
Nematode infestating plants that cause repeated disorder. Nematode is very unbalanced. For example, it likes to eat only sweet potatoes or only cucumbers, so by repeatedly making a series of times, there are more nematodes than eating crops that are making, the roots of the crop are eaten. If you change the crop to make without repeating, nematode will not be able to deal with different crops, and never increase.
For nematode harmfulness, there are usual ways to eradicate soil microorganisms with chlorine-based poison gas such as chloropicrin, but this method will conversely highlight distant harm. Nematode eggs are close to the state of death called cyst and can not be killed even with poisonous chloropicrin.
Conversely, because these gas will eradicate the living things that eat parasitic nematodes, for parasitic nematodes there will be a heaven without any foreign enemies.
For nematode damage, if you apply fertilizer with many actinomycetes or Bacillus and increase the diversity of microorganisms in the soil, the specific nematode that harms the crop will not be explosively increased.

Make "Aggregate structure" to increase retained fertilizer and make good quality soil
Bacillus subtilis and actinomycetes (such as Bacillus Natto) will release decapodation enzymes of strawberry and agglomerate the soil of the field.
Bacillus subtilis and Bacillus subtilis Natto digest proteins, fats, carbohydrates, whatever. Hard materials like cellulose will also decompose. The aggregate structure of the soil is made by soil dust dumpling with hardly decomposable substances such as cellulose and carbonaceous material of lignin and substances generated when bacteria decompose.


Cellulose and lignin are usually difficult to decompose, but they will be decomposed by mushroom bacteria, filamentous bacteria, and Natto bacteria.

The soil composed of aggregates has a moderate clearance, excellent drainage and water retention, and soft soil.
This leads to a rich soil that creates "soft soil" and delicious crops.

Bacillus subtilis produces plant growth hormone.

Bacillus subtilis secretes the plant growth hormone "Auxin" (Indole acetic acid)  in the process of proliferation.
Auxin promotes elongation growth of stem and root, growth of apical buds, enlargement of fruits, rooting, tissue

differentiation, etc., and inhibits sidebud growth, fruits and leaf detachment.

The reason why the fruit grows and the taste is said to be "Delicious", which is a characteristic of organic agriculture, is related to plant growth hormone.

Actually, it devises this kind of ingenuityZeolite made in Japan is increasing the number of households of useful microorganisms. Zeolite has characteristics as a porous material.
"Porous" is a state in which countless small holes are empty, and has the power to adsorb harmful substances and heavy metals.
In addition, this "innumerable hole" will be a perfect habitat for microorganisms, providing an environment where useful microorganisms in the soil can live, including "Bacillus subtilis".

Fermentation days exceeding 200 days. Because it is fermented firmly and it is ripe, it smells like as soil.

Borrowing the power of a superior degrader "Bacillus subtilis", and since it is aging fermentation for more than half a year, it causes little ammonia odor. When putting insufficiently fermented fertilizer into the soil, gas is generated and damage the roots of plants.
"Organic Pure Brown" is well aged due to fermentation days exceeding 200 days and the power of such bacteria.

What crops are suitable for?

  • Organic fertilizer " Organic Pure Brown " is alkaline fertilizer.
    Because it relaxes soil acidity acidified by acid rain and so on, the range of cropping is broadened.
  • Suitable for crops growing in soil ph 5.5 to 8.0.
