Bacterial lipases are important biotechnological enzymes used in various industries. They are mainly produced by bacteria such as Bacillus, Pseudomonas, and Burkholderia. Lipases are typically produced in the presence of lipidic carbon sources like oils, fatty acids, glycerol, or tweens, along with an organic nitrogen source. These enzymes are mostly extracellular and produced by submerged fermentation. They are commonly purified using hydrophobic interaction chromatography and other modern methods like reverse micellar and aqueous two-phase systems. Lipases can function in a wide range of pH and temperature, with alkaline ones being more common. They are serine hydrolases and stable in organic solvents. Some lipases show chemo-, regio-, and enantioselectivity. Recent research focuses on developing improved lipases through molecular approaches like directed evolution and metagenomics. Lipases are hydrolases that act on triacylglycerols to release fatty acids and glycerol. They are used in various industries, including food, detergents, and pharmaceuticals. Lipases can also catalyze esterification, alcoholysis, and acidolysis. They are versatile, with a wide substrate range, but are highly specific. Their catalytic potential can be enhanced through molecular imprinting, solvent engineering, and protein engineering. Lipases need to be stable and specific under application conditions. Lipases are produced by various organisms, including bacteria, fungi, and plants. Common bacterial producers include Achromobacter, Alcaligenes, Arthrobacter, Bacillus, Burkholderia, Chromobacterium, and Pseudomonas. Pseudomonas lipases are widely used in biotechnology. Several bacterial lipase-based products have been launched in the market, with applications in detergents and organic synthesis. Fermentation conditions significantly influence lipase production. Factors such as temperature, pH, nitrogen and carbon sources, presence of lipids, and dissolved oxygen affect lipase expression. Lipases are generally induced by lipid sources like oils, fatty acids, and glycerol. Their production is influenced by various factors, including the type of bacteria and fermentation conditions.Bacterial lipases are important biotechnological enzymes used in various industries.
