Optimization of Temperature for Extraction of Protease from Coconut Shells
Authors
Abstract
Proteases are the most important biomolecule in all organisms. It is present in all
organisms. There are different types of protease in the range of microbes to macrobes.
The main classes include Cysteine proteases, Aspartic acid proteases, Serine proteases,
Metalloproteases, Glutamic acid proteases and Threonine proteases. They play both
structural and functional roles and the types of proteases differ accordingly in different
organisms. The key role of Protease is selective and specific as its cleavage is limited for
a specific substrate. It also has potential therapeutic applications and with the help of this
enzyme, many diseases are cured like thrombolysis, cardiovascular disease and the
treatment of sepsis, cystic fibrosis, digestive disorders, inflammation and retinal disorders.
Proteases are also used for neuromuscular treatment. Other than these vital roles,
proteases are used in many industries like food, detergent, leather, etc., for different
purposes. In the performed study, Protease was isolated from Coconut shell chips and
Coconut shell powder at different temperatures such as 30°C, 50°C, 60°C, 80°C and
100°C. The optimum temperature for extraction of Protease from coconut shell was found
by estimation of protein, determination of Protease activity and performance of plate
assay. The extracts obtained were subjected to partial purification. Among the different
temperatures used for extraction, Protease concentration was found to be grater at an
extraction temperature of 100°C.
