Enzymes in soil: properties, behavior and potential applications.

摘要: Publisher Summary This chapter presents an outline of investigations performed on various aspects enzymes in soil—namely, (1) soil, as example “naturally immobilized enzymes,” (2) affected by natural and anthropogenic factors, (3) potential detoxifying agents polluted systems, including soils, with specific reference to phenolic pollutants. Three enzymes—invertase, phosphatase, urease—and pure clays (montmorillonite), dirty (montmorillonite covered different amounts OH–Al species), tannic acid, were used representative inorganic organic soil components. The influence metal (Al, Fe, Mn) species the interactions between acid was examined study discussed chapter. Synthetic enzyme complexes showed catalytic stability properties that depended matrix bonding mechanism involved their formation. Usually, a reduced activity kinetic behavior conforming Michaelis–Menten kinetics observed. Various responses terms thermal proteolytic Finally, potentiality laccase, oxidoreductive enzyme, detoxify phenol-polluted system addressed. satisfying efficiency toward molecules when acting presence complex (phenol-soil colloids suspensions).
