Using biotechnology for environmental protection
Synonyms: Enhancing protection of the environment through biotechnology
Context: This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities.
Implementation: Bacteria are being employed as sensitive chemical detectors. The method involves embedding the bacteria in a porous polymer matrix on the surface of a semi-conductor chip. The bacteria have been genetically engineered to emit a bluish glow in the presence of naphthalene, a component of jet fuels. When the bacteria start to glow, the chip sounds an alarm. The device is being used to detect traces of pollution after toxic-waste cleanup.
