Microbial communication during bioremediation of polyaromatic hydrocarbons

Human activity pollution has been shown to harm the environment, ecology, and health impacts. The polycyclic aromatic hydrocarbons (PAHs) produced by industries such as tannery, distillery, pulp paper, oil refineries are a major source of contaminant. PAHs found all across world, owing long-term human sources. PAHs' physico-chemical features, hydrophobicity electrochemical stability, contribute their environmental persistence carcinogenic effects. Numerous analytical biological techniques for qualitative quantitative assessment have proposed. Bioaccumulation, adsorption, chemical oxidation, photolysis, volatilization, microbiological degradation principal breakdown pathways in environment. Microbial populations, bacteria, fungi, algae, play crucial role elimination PAHs. Oxidase, manganese peroxidases, lipases, laccases enzymes involved breakdown. synthesis surfactants bacteria increases bioavailability improves process Temperature, pH, aeration, moisture content, nutrition availability, absence hazardous chemicals, kind number degrading microbial populations factors that influence decomposition. mechanisms result intermediate metabolites carbon dioxide mineralization. is improved molecular approaches gene engineering protein engineering. This review discussed benefits bioremediation strategies were investigated precise evaluation trusted at both regulatory scientific studies levels.
