Biocatalysis are used as natural catalysts, like protein enzymes, to perform chemical transformations on organic compounds. Both enzymes that have been more or less isolated and enzymes still residing inside living cells are employed for this task. Since biocatalysis deals with enzymes and microorganisms, it is historically classified separately from "homogeneous catalysis" and "heterogeneous catalysis". However, biocatalysis is simply a heterogeneous catalysis. food and agriculture; genetic engineering; molecular biology; healthcare and pharmaceuticals; biofuels; genomics; nanotechnology; environment and biodiversity; and bioremediation. Types of papers published are: Full-length original research papers; Short communications; Review articles; Letters to the Editor. Biocatalysis refers to the use of living (biological) systems or their parts to speed up (catalyze) chemical reactions. In biocatalytic processes, natural catalysts, such as enzymes, perform chemical transformations on organic compounds. Both enzymes that have been more or less isolated and enzymes still residing inside living cells are employed for this task
