Eminent Industrial and Biotechnological Applications of Laccases from Bacterial Source: a Current Overview.

Laccases are blue multicopper oxidases that oxidize a wide range of phenolic as well as non-phenolic substrates in the presence or absence of mediators. They occur in various species of bacteria, fungi, insects, and plants; bacterial laccases show high substrate specificity. Bacteria produce these enzymes either extracellularly or intracellularly and exhibit stability to a wide range of pH and temperature. Therefore, they are suitable for various industrial processes such as food, textile, and paper and pulp industry. They are also valuable for producing biofuels, pharmaceuticals, biosensors, and degradation of various environmental pollutants and xenobiotics compounds. Since bacterial laccases are more versatile in the sense of nutritional needs and ecological factors, their use can provide a promising solution to various problems related to industry and the field of biotechnology. However, there is a need for a thorough understanding of the chemistry and activity of bacterial laccases to enable their full potential use in bioremediation and biofuel production.
