Biotechnology: past and present

This Unit focuses on the historical development of biotechnology. The material is suitable for use either on its own or as contextual material for other Units.


Three themes run through the Unit:

  • The use of microorganisms by man as an ancient practice. Only very recently has scientific and technical change persuaded us to introduce a new term: 'biotechnology';
  • Case studies illustrating the historical development of biotechnology - e.g. bread-making, penicillin production, environmental management;
  • In each case scientific, historical and economic aspects are presented.

The Unit covers milestones in history and the main scientific and technological discoveries in fields linked to what is now called biotechnology.

NEW: Now includes Saccaromicio, a cartoon history of yeast (part 2 above).
