Lipases for applied biocatalysis

Lipases have received great attention as industrial biocatalysts in areas like oils and fats processing, detergents, baking, cheese making, surface cleaning, or fine chemistry [1,2]. They can catalyse reactions of insoluble substrates at the lipid-water interface, preserving their catalytic activity in organic solvents [3]. This makes of lipases powerful tools for catalysing not only hydrolysis...

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...

Bacterial 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...

Inhibition of lipases by -polylysine

Oral administration of -polylysine to rats reduced the peak plasma triacylglycerol concentration. In vitro, -polylysine and polylysine strongly inhibited the hydrolysis, by either pancreatic lipase or carboxylester lipase, of trioleoylglycerol (TO) emulsified with phosphatidylcholine (PC) and taurocholate. The -polylysine concentration required for complete inhibition of pancreatic lipase, 10 g...

Bacterial lipases and chronic blepharitis.

Eyelids and conjunctivae of 36 normal individuals and 60 patients from six clinical groups of chronic blepharitis were cultured for aerobic and anaerobic bacteria. The most common species isolated were coagulase-negative staphylococci (C-NS) and Propionibacterium acnes. All strains of these species, and all Staphylococcus aureus strains isolated were tested for the ability to break down triglyc...
