Microorganisms are everywhere. They are usually invisible to the naked eye, but they are abundant in the air we breathe, soil, water, our skin and hair, our mouth and intestines and the food we eat. They enrich the soil and make the environment clean. They changed our food. Some of them protect us from harmful microorganisms. However, most people are almost unaware of their existence unless they are sick. Microorganisms called "bacteria" are regarded as dirty and unwelcome things, because a few of them will make people sick and a few will spoil food. However, on the whole, microorganisms present us with a fascinating little creature. Together, these microorganisms can complete all the processes that can be realized on the earth and have a far-reaching impact on our lives and the surrounding environment.
