Biocatalysis is basically two words joined together; Bio and Catalysis. “Bio” prefix denotes biological and “catalysis” means the acceleration of a chemical reaction due to a catalyst. So in general biocatalysis is the use of biological (natural) catalysts, such as enzymes. These biological catalysts are used to transform organic compounds chemically. An enzyme is a protein catalyst that is responsible for the reactions in your body. Enzymes help with digestion of food, production of essential nutrients, movement of muscles, etcetera. Enzymes not only exist in our body but are used for quite a lot of other

They have been used since hundreds of years for the production of alcohol and the fermentation of cheese through the enzymatic breakdown of the proteins in milk. Science has excelled over the past few years. This has led to a better understanding of the “protein structure-function relationship” which has augmented the range of biocatalytic applications. Rational design, in chemical biology and biomolecular engineering, is the strategy of creating new molecules with a specific functionality, based upon the ability to forecast how the molecule's structure will affect its behavior through physical models. Rational designs are related to biocatalysts because it directs evolution which results in very specific protein variants for the enzyme. The enzyme can therefore be engineered to have the desired properties. These properties include stability, activity, selectivity and the substrate specificity. In the present era, Biocatalysis is being implemented in chemical, agricultural, pharmaceutical and food industries. Despite being used on such a scale, the true potential of Biocatalysis is yet to be …show more content…
Oxidases, peroxidase, oxygenases, dehydrogenases
Transferases Required for the catalysis of group transfer reactions. Glycosyltransferases, tansaminases, transketolases, acyltransferases
Hydrolases Provides catalysis for hydrolytic reactions. Lipases, protease, esterases, glycosidases, phosphatases
Lyases Catalyze nonhydrolytic removal of groups. Decarboxylases, ketolasesm dehydrateses, aldolases, hydratases
Isomerases Catalysis of isomerization reactions. Racemases, isomerases, epimerases,
Ligases Catalyze the synthesis of various kinds of bonds with the help of energy containing molecules. Carboxylases, synthetases
Table 3: Enzyme classification

They catalyze the oxidation and reduction reactions that take place within the cell. They are very desirable in the industry because of their ability to catalyze specific types of reactions. They, however, need expensive cofactors.
These enzymes catalyze the transfer of functional groups such as methyl, glycosyl, hydroxymethy and etcetera. They are not extensively used in industrial processes but ehy are used in some

E-mail: Received: May 22, 2012 Accepted: June 16, 2012 Online Published: June 25, 2012 doi:10.5539/jsd.v5n7p80 Abstract Small and medium scale industries in Nigeria play a major role in polluting water bodies, and key among these pollutants are suspended solids, biological oxygen demand and heavy metals contamination. Conventional methods of treatment, such as chemical precipitation, do not provide sustainable solutions as the pollutants are merely transferred from the waste water to a sludge residue which is disposed of by land-filling. The pollutants eventually find their way to freshwater supplies thereby contaminating it. Water hyacinth is a noxious weed that has a rapid growth rate and easily congests the water ways in Lagos, a coastal city in Nigeria, thereby creating serious problems in navigation, and irrigation. This can be harvested, and in line with the golden rules of sustainable development, used for the......

...2009 Award Winning Essays Organized by Supported by The Goi Peace Foundation UN ESC O Japan Airlines Foreword The International Essay Contest for Young People is one of the peace education programs organized by the Goi Peace Foundation. The annual contest, which started in the year 2000, is a UNESCO/Goi Peace Foundation joint program since 2007. The United Nations has designated 2001-2010 as the "International Decade for a Culture of Peace and Non-Violence for the Children of the World" and 2005-2014 as the "United Nations Decade of Education for Sustainable Development." Not only should young people benefit from these global initiatives, but they should be empowered to play a leading role in them. Each year, the essay contest adopts a theme relevant to building a Culture of Peace and a sustainable future, such as "Respect for life," "Caring for our planet," "Learning to live together," and "The role of media and ICT in building a peaceful world." The theme of the 2009 International Essay Contest for Young People was "The role of science in building a better world." Scientific progress has brought many benefits to humanity, while some applications of science have had adverse impacts. Young people were invited to express their vision for the future of science, and the kind of studies or researches they wish to engage in. 4,506 essay entries were received from as many as 134 countries. This publication contains a total of 16 essays: First Prize, Second Prize and Third Prize...
