Most procedures in biotechnology use a variety of biological systems such as microorganisms, plants and animals as well as their respective cell and cell components for technical applications that can be used by humans. The efforts undertaken in Biotechnology focus on identifying, synthesizing and metabolizing specific substances as well as degrading others that are potentially harmful to humans and their environment. Yet other efforts attempt to increase usability and propagation of ornamental and agricultural plants or support their conservation. Therefore, in many ways, biotechnology is certainly a key science in the landscape of modern biology; its contribution to techniques and products will have an increasing impact in the next century not only on the economy but also on a day to day basis. Hence, the chances for scientists with profound knowledge of this interdisciplinary science are tremendous.
