Fermentation is a collaborative enterprise of people and microbes. We provide the microbe a habitat,
and the microbe uses that habitat to produce a substance useful to people. From yoghurt to cheese,
miso, and natto, people have lived with microbes since long ago, and fermented products have come
to contribute to our health.
Recently, biologically active agents produced by microbiological control, such as by fermentation,
have attracted attention. Their effectiveness is not limited to the food field, and they can also be
found in the cosmetics field. The great thing about fermentation is that an unlimited number of
combinations can be existed depending on the material and type of organism. It is indeed a field of as
yet unknown potential.
