Mangrove ecosystems are well known for their ecological significance and serve as vital reservoirs of unique microbial diversity. The microbial communities from the mangrove ecosystems have the ability to synthesize economically important by-products, influencing different industries such as food, cosmetics, pharmaceutical, paper and pulp, and other industries. These mangrove microbial populations and their derived metabolites are also playing a pivotal role in biodegradation and bioremediation processes in order to reduce the toxicity of various pollutants released into the environment. This study comprehensively examines the biodegradation and bioremediation efficacy of bacteria associated with mangrove environments. It delves into the diverse metabolic capabilities of these bacteria, elucidating their ability to break down a variety of organic contaminants, such as pesticides, hydrocarbons, heavy metals, and organic solvents. The mechanisms underlying biodegradation, such as enzymatic action and genetic adaptations, are explored to provide insights into the microbial degradation processes.
