Soil may be looked upon as a biological entity. Soils contain free enzymes; immobilized extracellular enzymes stabilized by a three-dimensional network of macromolecules and enzyme proteins within microbial cells. Each of the organic and mineral fractions in both bulk soil and rhizosphere has a special influence on the total enzymatic activity of that soil. The study of enzymes, in general, is a subject of interest to many disciplines in science ranging from biology to physical sciences.
