This review we briefly summarize related recent progress on isolation of microorganisms for pollutant degradation in extreme conditions and the study of genes and enzymes related to biodegradation pathways. This paper also reviews various parameters like effect of metal ion, pH, carbon sources etc. and information on enhancement of biodegradation of genetic Engineering was also mentioned in detail. Keywords: Environmental pollution, Industrial pollution, Microbial pollution, Genetic engineering, Metabolic pathways. I. Introduction A. Environmental biotechnology The Environmental biotechnology started with wastewater treatment within the turn of the 19/20th century [1] and provided services for the removal of contaminants from wastewater and soil, to monitor pollutants and harmful materials within the environment and to recovery valuable products from waste [2]. In recent decades, it's offered many methods for environmental pollution and has become a technology for sustainable development. Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds [1]. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms. Biodegradation provides useful strategies towash up many sorts of and xenobiotic pollutants like polycyclic hydrocarbon (PAH), organic metals, and halogenated or sulfur compounds[2–3]. The combination of genetics and process engineering, biodegradation and decomposition
