Biological nitrogen fixation accounts for almost 70 percent of nitrogen for plant growth. If food is to keep abreast of population growth, even more nitrogen must be fixed. For this international research institutes continue the search for natural variants in the bacterial population while also pursuing novel genetic engineering methods. (Author)

Mid-nineteenth century work by Mendel on plant hybrids and by Pasteur on fermentation gave birth by way of bacterial genetics to modern-day molecular biology. The bacterium Escherichia Coli has occupied a key position in genetic studies leading from early gene identification with DNA to current genetic engineering using recombinant DNA technology.…

Discussed is the recycling of agricultural residues, either through fermentation or bioconversion processes, to help meet the energy requirements of the developing countries. (BT)

Discusses the current use of microbial technology in industrialized countries to develop substitute sources of fuel, food, and fertilizer and why it is important for developing countries to adopt the techniques described to gain economically. A list of references is also presented. (HM)

Prospects for microbial technology are discussed including: (1) possible transfer of nitrogen-fixing ability directly from bacteria to plant; (2) increasing food needs met through single-cell proteins and fermentation; (3) microbial production of antibiotics; and (4) increased biogas production.

The sword-tailed horseshoe crab (Limulus polyphemus) has developed its own defense against bacteria surrounding it. This defense system, under the name "Limulus test," now provides medicine and hygiene with a valuable means of detecting bacterial endotoxins at extremely low levels. (Author/JN)

Discusses the use of microbes over the centuries in the quest for new/improved foodstuffs; microbial benefits to public health, medicine, and for farmers in developing countries; and microbial applications to energy, industry, and mining. (JN)

A review of great epidemics (rat-borne, plague, smallpox, cholera, influenza, rabies, tuberculosis) reveals the devastation they have caused. Success in the battle against these is being won through hygiene, sanitation, vector control, and vaccines, especially since microbiology has provided a rational understanding of the diseases.

Bioinformatics embraces powerful new knowledge and techniques which, Janus-like, promise advances in medicine and agriculture and threaten new weapons for warfare. To guard against misuse of bioknowledge, nations must foster free international communication against experts. (Author)
