Skip to 0 minutes and 14 seconds So what is biotechnology? Biotechnology, the original definition by Karl Ereky in 1919, is biology based technology. Now this is a very broad and the general definition. The modern definition is more specific. Technologies that use living organisms, living cells, cell culture or even enzymes, in the production or modification of drug. And biotechnology product, of course, are the product produced by the use of biotechnology. For example, the first biotech products, humanized insulin was marketed in 1987 by Eli Lilly and the Genentech. Let me start out with the biotechnology history now. 6000 B.C. farmers already know how to select seeds for replanting and select livestock for breeding. So that’s biotechnology based on the broad definition of biotechnology. 5,000 years B.C.
Skip to 1 minute and 34 seconds people used yeast to ferment wine and bread. 1000 B.C. lactic acid producing bacteria was used to make yogurt and cheese . This is the cheese making process Cheese is made from raw milk. And that during the cheese-making, the most important step is the addition of microorganisms. And this organisms, microorganisms included Lactococci, Lactobacilli, Streptococci and for the very famous swiss cheese, the Propionibacterium shermanii.
Introduction to Biotechnology
At its earliest, biotechnology was simply defined as any technology based on biology (Karl Ereky, 1919). By this general definition, humans practiced biotechnology very early in civilization, including the selection of seeds for replanting and livestock for breeding. Modern biotechnology exploits principles, techniques and tools to manipulate living organisms and biological systems for the production or modification of biologics.
Coined by Karl Ereky in 1919, biotechnology has evolved into a distinctive scientific discipline and multi-billion dollar industries. Cheese, yoghurt, bread, beer and wine are all made by fermentation, a biotechnological process that involves microorganisms. These dairy products not only advanced biotechnology but provided pleasure to early human civilization. The first biotechnology product, rh-Insulin was marketed in 1987 by Lilly/Genentech.
Have you ever make cheese before? Do you know other usages of microorganisms?
