Application of enzymes in industry and medicine.

Extracts from this document...


Application of enzymes in industry and medicine. Enzymes have enormous potential in the commercial world. Since they can catalyse specific reactions at relatively low temperatures, they are more versitale and cheaper than inorganic cataylstys. Enzymes can work out a range of Ph levels and normal atmospheric pressure therefore energy saving. Enzymes are biogradable and therefore cause less environmental pollution. Enzymes are formed from within the cells of all living creatures, plantsm fungi, bacteria and microscopic single celled orgainisims. They are produced commercially by fermentaion under aseptic conditions. The nutrient is converted to the desired enzyme by carefully selected micro orgainism choice and type of conditions to yield the type of enzyme. Enzymes are used in a wide range of industries, including the food industry, textiles, argricultrial forestry, medical and the brewing industry. Baking Enzymes are very important in the baking process. The main function of enzymes in baking is to convert starch into fermentable sugars. The carbon dioxide produced from yeast fermentation of these sugars gives bread its fluffy texture. ...read more.


During conditioning proteases, most commonly papain are added to prevent the formation of chill haze, a carbohydrate complex. Papain causes the beers faming and head rention. Glucoamylasecan also be added resulting in maximum alcohol content and a sweeter beer. Food industry Lipases have a tremendous advantage in the food industry, however the biggesty problem is their high cost. Lipases are priciply usd in the dairy imdustry for the enhancement of flavour and ripening of cheese. Free fatty acids in cheeses, particualary soft cheeses give them their charcteristic flavours and smells. Blue cheeses are ripened by extracelluar lipases from mould, eg penicillium roqueforti. Leather industry Enzymes are used to remove the hairs from the animal skins to produce leather. A protease enzyme is used,eg trypsin, which partly digests keratin, the main protein present in hair, allowing the hair to vbe more gently removed.Protein digesting enzymes extraxted fro the pancreas of animals are used to diffuse into the skin and break down the proteins around the hair follicles. ...read more.


An enzyme called Phytase is used which releases phosphate and phyate. Treatment of animal feeds with phyate has shown to increase the levels of phosphate, thefore reduce the amount of inorganic, unenvironmental;ly friendly phosphate that has to be added to the feed. Phosphate has to be added to the feed for animals, such as pigs, with single stomachs, therefore low phosphate availability. Medicine Enzymes are tremendously useful in medicine, aswell as being advantageous for industirial processes and the commercial world. Most genetic diseases are a result of a particular enzyme deficiency. Therfore enzymes can be used in the diagnosis of disease, and therefore correct certain illnesses.The presence of enzymes where they shouldn't be , is vital for diagnosing a disease. For example when the liver is diseased or damaged, enzymes only usually found in the liver leak into the bloodstream. Testing the blood for these activities is therefore vital for confirming liver damage. Enzymes in medicine are also used in analytical tests. For example glucose is measured by an enzyme based test utilising glucose oxidase. Biosensers are used which analyse biologically active compounds in solutions. Biosensors are tremendously useful, in measuring blood levels. Sophie Parslow 28/04/07 ...read more.

  2. The use of protein digesting enzymes (proteases) in industry

    [3] Fungal enzymes have been a part of the dietary supplement industry for several decades. In the dietary supplement field these enzymes are primarily used fro two applications: Digestive and Systemic. Fungal proteases are also used in systemic applications that involve the control of inflammatory conditions.

    This further illustrates the point that proteases are used widely in medicine. Enzymes are also used to cure illnesses for example "nuclease is considered as a possible therapy for cystic fibrosis," (5) and L-asparginase is used in cancer chemotherapy as it removes the nutrient needed for tumour growth in tissues, (7).

    * The yield can be increased by means of strain selection, mutation and optimisation of growth conditions. * They can be grown in laboratories and are not influenced by climate. * They occupy a great variety of habitats and extremes of pH and temperature.

    of enzymes are less harsh on the fabric so it results in a quality product. In the tanning of leather industry protease is used which is obtained from dog and pigeon faeces to remove hair and make the leather pliable.

    * Proteases are also used in wound therapy. In this case they are called debriding agents and are used to clean a wound and therefore accelerate the healing process. * Some proteases are also used as anti-inflammatory reagents. An enzyme called super oxide dismutase is also available as an anti-inflammatory agent.

    Only around 10% in turn come from nature sources of microorganisms, such as fungi, yeast species and bacteria species. The chosen microorganisms are usually cultured in large fermentation chambers under controlled conditions to maximise yield. Large numbers of microbes are grown in specific growth media.

    Protease and amylase are primarily used to remove the food. These products are more environmentally friendly as they contain less bleaching agents and phosphates. (4) As well as being used in industry, enzymes are also commonly used in medicine. The most commonly known uses of enzymes in medicine use ELISA (enzyme-linked immunosorbant assay)
