Traditional biotechnology refers to the time-honored practices of working with living creatures to create or alter crops and other valuable goods for human use. It includes techniques such as breeding animals and crops, using microbes to produce beer, wine, cheese, and yogurt. Traditional biotechnology may also include the products of tissue culture, micro-propagation, or various strategies used to eliminate disease. The focus of traditional biotechnology is on active techniques which have great efficiency and accuracy. Modern biotechnology, on the other hand, incorporates a specific focus on industrial usage of rDNA, cell fusion, and novel bioprocessing techniques.
