What Will Natto Bactiria Grow On?

Rice straw, which has naturally occurring Bacillus subtilis on its surface, was traditionally used in the preparation of natto. This was accomplished by wrapping boiling soybeans in rice straw. By doing so, the bacteria were able to ferment the sugars that were already present in the beans, which resulted in the production of natto.

BACILLUS SUBTILIS NATTO. It is a kind of gram-positive bacteria that may be discovered in the digestive systems of mammals. The cells, which normally take the form of rods, proliferate at temperatures ranging from 25 to 35 degrees Celsius. It is able to acquire protection against a wider variety of stresses, including acidic, alkaline, oxidative, and thermal conditions, more rapidly.

What is Bacillus natto made of?

When Bacillus natto ferments soybeans into natto, it also creates a wide variety of useful components, such as nattokinase, vitamin K2, polyglutamic acid, and a number of others. There are a lot of businesses that sell those individual components, but not the natto itself. Soybeans continue to be the medium of choice for optimal growth when cultivating B. subtilis at an industrial scale.

Can B Natto help increase lactic acid bacteria?
