Esterases are ubiquitous enzymes found in all living organisms, including animals, plants, and microorganisms. They are involved in several biological processes, including the synthesis and breakdown of biomolecules, such as nucleic acids, lipids, and esters; phosphorus metabolism; detoxification of natural and artificial toxicants; polymer breakdown and synthesis; remodeling; and cell signaling. The present review focuses on the most industrially important esterases, namely lipases, phospholipases, cutinases, and polyethylene terephthalate hydrolases (PETases). Esterases are widely used in industrial and biotechnological applications. Notably, the biotechnological production of esters, including methyl acetate, ethyl acetate, vinyl acetate, polyvinyl acetate, and ethyl lactate, as an alternative to chemical production, represents a multi-billion-dollar industry. Currently, most enzymes (>75%) used in industrial processes are hydrolytic. Among them, lipases and phospholipases are primarily used for lipid modification. Lipases are the third most commercialized enzymes after proteases and carboxyhydrases, and their production is steadily increasing, currently representing over one-fifth of the global enzyme market. Esterases, particularly lipases, phospholipases, and cutinases, are employed in cosmetics, food, lubricants, pharmaceuticals, paints, detergents, paper, and biodiesel, among other industries. Overall, biotechnological production using enzymes is gaining global traction owing to its environmental benefits, high yields, and efficiency, aligning with green economy principles.
