Organic Toxicants

"Environments are often contaminated with both metals and organic toxicants. In such mixed pollution, metal tolerance plays an important role in growth and metabolic functioningof biodegrading microorganisms, and is a desirable trait in bioremediation applications. Hence, those organisms that can tolerate and grow in presence of metals while degrading the organic toxicants are the potential bioremediation agents of choice. Filamentous fungi have been investigated for their metal tolerance and utilized in bioremediation due to the ease of growing and handling these organisms and their versatility in biodegradation of normally recalcitrant organopollutants. Organic xenobiotics absorbed by roots and leaves of higher plants are translocated by different physiological mechanisms. The following pathways of xenobiotic detoxication have been observed in higher plants: conjugation with such endogenous compounds as peptides, sugars, amino acids, and organic acids; oxidative degradation and consequent oxidation of xenobiotics with the final participation of their carbon atoms in regular cell metabolism. The small parts of xenobiotics are excreted maintaining their original structure and configuration. Enzymes catalyze oxidative degradation of xenobiotics from the initial hydroxylation to their deep oxidation. The wide intracellular distribution and inductive nature of oxidative enzymes lead to the high detoxication ability. With plant aging, transformation of the monooxygenase system into peroxidase takes place.
