2 On-line support for teaching For lecture notes and lab schedules: – http://www. extremophiles .net • Username: student • Password: microbiology – After login click ‘downloads’ icon on main menu to see ±les available for download – NOTE • some Microsoft IE versions do not support this site, if you have trouble login via – http://www.webdesignasia.com/extremophiles This on-line book is also really useful: – Microbiology and Bacteriology - The World of Microbes – http://www. bact . wisc . edu/Microtextbook/index . php Examination • A one-hour multiple choice examination containing 60 questions –(70% of overall grade) • An assessment of three written lab reports –(30% of overall grade) So now lets have the ±rst lecture What are microorganisms? • Quite simply, a microorganism is an organism that you can only see using a microscope!

3 They are incredibly diverse in both structure and function Microorganisms occur in all the Domains of life: Eukaryotes (cells with nuclei) – Algae, fungi, protists – (basically these are single-celled versions of animals and plants) Bacteria (prokaryotes) – There are at least 18 different ‘kingdoms’ of bacteria Archaea (prokaryotes) – There are 4 kingdoms of archaea Viruses – These are not cellular but they are included as microorganisms How were microorganisms
