Soil micro-organisms that decompose cellulose have a very important place in the transformation of carbon in nature, since under natural conditions plant residues, which contain relatively large amounts of cellulose, are continually being added to the soil. It is estimated that in forest soils bacterial activities alone account for the liberation of about nine kilograms of carbon dioxide in one hour. Since cellulose constitutes from one-third to one-half of the weight of all plant residues, a considerable quantity of this polysaccharide is being constantly disintegrated by micro-organisms with the eventual liberation of carbon dioxide.
