Bioremediation, which uses biological processes to cleanse and heal polluted environments, offers a more sustainable alternative to standard remediation approaches. This field uses microbes, plants, and fungi to break down, convert, or sequester toxic pollutants in soil, water, and air. Among these biological entities, cyanobacteria stand out for their ecological resilience and diver’s metabolic capacities. Their capacity to photosynthesis, fix nitrogen, and metabolize a wide spectrum of organic and inorganic chemicals makes them excellent candidates for a variety of bioremediation applications. These microbes flourish in polluted environments, decomposing substances including heavy metals, insecticides, and hydrocarbons. Their synthesis of extracellular polymeric compounds improves their ability to immobilize and sequester pollutants. Biotechnological approaches to bioremediation are constantly evolving in response to advances in genetic engineering, synthetic biology, and systems biology. Scientists can improve cyanobacteria and other microorganisms’ natural abilities to degrade and detoxify pollutants by modifying their genetic makeup. For instance, by introducing specific genes, microorganisms can target and degrade complex organic pollutants that would otherwise be resistant to biodegradation.
