Microbial detergent compatible lipases
Most of the companies are not currently manufacturing the detergents alone; they are producing enzyme-based detergents. More than 50% of the detergents produced in the developed countries presently contain enzymes to improve the detergency by removing tough stains. The role of a detergent lipase is to digest the lipidic molecules from the soiled substrates. Most of the chemical detergent ingred...
متن کاملMicrobial lipases form versatile tools for biotechnology.
Lipases are secreted into the culture medium by many bacteria and fungi. They catalyse not only the hydrolysis but also the synthesis of long-chain acylglycerols. Important uses in biotechnology include their addition to detergents, the manufacture of food ingredients, pitch control in the pulp and paper industry, and biocatalysis of stereoselective transformations. This makes them the most wid...
متن کاملGluconic Acid: Properties, Applications and Microbial Production
Gluconic acid is a mild organic acid derived from glucose by a simple oxidation reaction. The reaction is facilitated by the enzyme glucose oxidase (fungi) and glucose dehydrogenase (bacteria such as Gluconobacter). Microbial production of gluconic acid is the preferred method and it dates back to several decades. The most studied and widely used fermentation process involves the fungus Aspergi...
متن کاملBacterial lipases for biotechnological applications
Lipase genes originating from the Gram-negative bacteria Serrutiu marcescens and Pseudomonus urruginosa were cloned. S. marcescens lipase was overexpressed in Escherichia coli yielding inclusion bodies which were purified and finally refolded to give enzymatically active lipase. The lipase operon of P. aeruginosa consisting of genes 1ipA and lip14 was cloned behind the T7 410 promoter and overe...
متن کاملInhibition of microbial lipases by fatty acids.
Addition of lard or sodium oleate to the medium used for lipase production by Pseudomonas fragi resulted in a decreased accumulation of lipase in the culture supernatant fluid without affecting cell growth. The production and activity of lipase was inhibited by lard, sodium oleate, and the salts of other unsaturated fatty acids. Some divalent cations, Tweens, lecithin, and bovine serum prevente...
