Excerpt from A Manual of Bacteriology

In what may be termed the economy of nature micro organisms are all-important; without them there would be no putrefaction, no decay, and the dead remains of animal and vegetable life would accumulate and encumber the earth, which would become barren for the want of the organic matter originally derived from it, but of which there was no return. In fact the higher plants, and indirectly, therefore, animals also, are dependent for their existence upon the presence of bacteria in the soil, which break up and render assimilable complex substances used as manures.
