Screening and Growth Kinetics Studies of Microalgae as a Novel Source for Antitumour Enzymes Production

Abstract

1.1 Enzymes Microbial sources have been a major source for enzymes that are employed for the daily needs of humans. They are the biological catalysts that accelerate a chemical reaction without undergoing permanent changes in the structure. The history of modern enzyme technology era kick started in the 19th century when Louis Pasteur concluded while performing fermentation of sugar to alcohol by yeast that it was being catalyzed by a vital driving force called “ferments”, found within the yeast cells. The term “enzyme” was coined by a German physiologist Wiliam Kuhne in 1978, which comes from Greek word ενζυμον that means "in leaven", to describe this process. Currently a massive interest has been generated in the use of enzymes especially in food, pharmaceutical, environmental and detergent industries ranging from low purity to highly pure pharmaceutical grade enzymes.
