Analysis and Fate of Surfactants in the Aquatic Environment, Volume 40 (Comprehensive Analytical Chemistry)

An realizing of the destiny and behavior of natural chemical substances, equivalent to surfactants, within the surroundings is a prerequisite for the sustainable improvement of human wellbeing and fitness and ecosystems. As surfactants are being produced in large quantities, it is very important have an in depth wisdom approximately their lifetime within the surroundings, their biodegradability in wastewater therapy crops and in usual waters, and their ecotoxicity.

The aromatic benzene nucleus is susceptible to aerobic and anaerobic metabolism, although the latter occurs relatively slowly. Overall, however, the presence of halogen atoms on the aromatic ring governs biodegradability. A high degree of halogenation may prevent aromatic compounds from being aerobically metabolized, as is the case for highly chlorinated PCBs. However, as discussed above for the aliphatic compounds, anaerobic microbes can remove chlorine atoms from the highly halogenated aromatics.

Through a series of internal electron transfers catalyzed by the microorganisms, the organic contaminant is converted to innocuous compounds known as fermentation products. Examples of fermentation products are acetate, propionate, ethanol, hydrogen, and carbon dioxide. Fermentation products can be biodegraded by other species of bacteria, ultimately converting them to carbon dioxide, methane, and water. Secondary Utilization and Co-metabolism. In some cases, microorganisms can transform contaminants, even though the transformation reaction yields little or no benefit to the cell.
