The development of recombinant DNA technology has created a new upsurge of interest in biotechnology--the harnessing of micro-organisms and plant microbial cells for the production of specific materials of direct use to man or for the improvement of the environment. Discussing both traditional and emerging aspects of the science, this unique book reviews numerous exciting applications of biotechnology in developing countries, emphasizing that a small improvement in energy efficiency, utilization, or generation may have far-reaching effects in improving the quality of life of people in poor communities.
