Solvents and detergents are important in a number of industries and most are derived from petroleum. There is increasing concern that prolonged contact with solvents causes health problems – for workers in the factories where solvents and detergents are produced, and for those using such substances in their everyday work. There are two additional drawbacks to these solvents and detergents: one day the crude oil from which they are derived will no longer be available; and they present a major waste
15 - 20 Bleach and/or enzyme preparation These are considered together because they both perform a similar function - removing stains, which the other ingredients would find difficult to deal with. The most commonly used bleaching agent is sodium perborate. It is oxidizing bleach, removing stain such as tea, coffee and fruit juice. It acts at temperatures above 600C. A number of detergents incorporate an enzyme preparation which digest protein. Enzymes are active between 10oC and 60oC
Introduction To meet the increasing demand of robust, high turnover, easily and economically available biocatalyst, research is always channelized to get novelty in enzyme or improvement of existing enzymes by engineering at gene and protein level [1]. Enzymes derived from microbial source are generally regarded as safe and they are functional at wide range of temperature, pH, salinity or other extreme conditions. Actinomycetes are one of the most diverse groups of microorganisms that are well characterized
cells is usually negligible. This is a limitation of this procedure. Enzyme treatment Lysozymes and enzyme extracts from leucocytes, Streptomyces spp., Micromonospora spp. Penicillium spp., Trichoderma spp., and snails cause hydrolysis of specific bonds present in the cell walls of microbes. But this process is very expensive. The downstream process can also become very complicated because the enzymes used and the enzymes isolated have to be distinguished and separated from each other.

such as plants and microorganisms to produce and process material, chemicals, and energy . An example could be detergent. Industrial biotechnology modifies the actions of enzymes and microorganisms to improve the effectiveness of detergents so clothes can be washed at lower water temperatures . Washing at lower temperatures also results in more power efficiency. Similarly, laundry detergent has been made more eco-friendly and has solved phosphate water pollution problems in the 1970s . Industrial biotech
INTRODUCTION Detergents are designed for cleaning purposes. They are often used for assisting the removal of dirt or other materials from contaminated surfaces. The active chemical ingredients of detergents are termed as surfactants or surface-active agents (Scott et al., 2000; Yahaya et al., 2011). Detergent formulations consist of surface-active agents, surfactants. Thus, they are called as amphiphilic substances because one part of the detergent is hydrophilic and the other part is hydrophobic
applied enzymes due to their specific hydrolysis of ester bonds between various substrates like acylglycerol, oil or other lipid molecules. Lipase producing microorganisms are found in industrial water, soil contained with oil, oilseeds, coal crest, vegetable oil processing factories, compost blend, decaying food and dairies product.Among different bioresources
Enzymes are proteins that act as biocatalysts for a large number of reactions. They function in the transformation of macromolecules to energy and new materials, besides for growth, repair and maintenance of cells. The important of enzyme are for the degradation of the complex molecules, pectin in the middle lamella and the primary cell walls of young plant cells (Kashyap et al., 2001). The technology of enzyme become an important part in food industry. Earlier, there was limited to small number
Effect of different temperatures on amylase activity. Literature review This study is an attempt to follow the activity of amylase because it has a major role in the life of living organisms and is found abundantly in them. Amylase is a catalytic enzyme which hydrolyzes starch into maltose and dextrin at a certain temperature (Biology.kenyon.edu, 2015). In plants such as fruits and vegetables carbohydrates are referred to starch which is polysaccharide and is converted into disaccharide and eventually
Ethyl and hexyl esters are among the important and versatile components of natural flavours and fragrances. Ethyl Laurate is widely used in food , aromatics, flavours, pharmaceuticals, detergents and cosmetic industries[1]. Traditionally, most of the flavour compounds are produced by chemical synthesis or extraction from natural sources. Recently most esterification reactions are catalyzed by inorganic acid, solid acids, Lewis acid, ion-exchange resin and metallic compounds [2,3]. These methods required
