Biotechnology: Biotechnology is not easy to define. We can say that it is the large scale industrial use of biological processes from microorganisms to make substances or to provide services for man. The term of “biotechnology” was coined only in the 1970s, inspired by work carried out to produce genetically engineered organisms. As a result, biotechnology is usually linked to genetic engineering and the production of the specific products (e.g. enzyme and hormones) of genetically engineered organisms. Historically, however, we have been using the ability of microorganisms to carry out fermentation for hundreds of years to produce foods such as bread, cheese, and yogurt.
