Abstract
Biocatalysis involving certain enzymes like NHase, Nitrilase, Tannase and Amidase produces certain commercially important compounds .NHase are used for the synthesis of certain compounds such as acrylamide and nicotinamide. Thermostable Nitrilase from the Rhodococcus strains is used for the modification of acrylic fiber surface. The activity of amidase enzymes is five times increased and inhibited with the use of Co2+and Hg2+, 2-mercaptoethanol, dithiothreitol, and ethylene diaminetetraceticacid respectively. Furthermore the production of amidesis done as a by the help of a nitrilase-catalysed reaction of a heterolytic amino nitriles by a enzyme. For the hydrolysis of Gallic acid esters and hydrolysable tannis the tannase is use as catalyst and this gallic acid is produced by the hydrolysis of methyl gallate by fungal tannase, the tannase activity is also shown by lactic acid bacteria and the nitrilase is used for the modification of acrylic fibers by the help of a reaction media with some parameters like time, enzyme activity and its formulation.
