Fermentative extraction of Amylase using waste Biomaterials as Substrate

Enzymes are biological molecules that significantly speed up the rate of virtually all of the chemical reactions that takes place within the cells. They are vital for life and serve as a wide range of important functions in the body. Solid state fermentation holds a high potential for the production of enzyme amylase using Aspergillus niger. In this work, different solid substrates such as groundnut shells, coconut coir and Palmyra sprout peels were used for the production of amylase as they are very cheap and also easily available raw materials. Then the maximum enzyme activities were analysed. Results showed that the enzyme activity of for which palmyra sprout peel was used as substrate had maximum activity in both crude sample (0.63μmol/ml.min) and in partially purified sample (1.42μmol/ml.min) and activity was found to be less for groundnut shell as substrate (crude sample 0.36μmol/ml.min) and in (treated sample 0.26μmol/ml.min) and also the specific activity was found to be maximum in palmyra sprout peel (29.2U/mg of protein) and less in groundnut shell (8.6U/mg of protein).
