Major concepts to review for Exam 1: 1.) know the elements of life – and how the reduction and oxidative of some of these drive bioenergetics 2.) Know the general time line for biology and evolution on the Earth; What major events altered evolution especially in terms of microbially driven changes 3.) Carl Woese – what did he contribute? What kind of biological molecules are best to generate phylogenetic trees‚ and why? How does this compare to enzymes? 4.) What defines a species (formal definitions)

c) In what ways did the understanding of the treatment of disease change in the years 1860-1945? The treatment of disease changed dramatically in the years 1860-1845 due to the changes of how people understand it‚ how each discovery such as Pasteur’s opens new doors‚ leading to other discoveries such Koch’s identification of germs‚ the magic bullet and discovery of penicillin. this has help society to understand the causes of disease‚ and the ways to tackle it. These discoveries began in

REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and

BACKGROUND Introduction The development of dyes to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification. (http://inst.bact.wisc.edu/‚ © 2006-2013 Microbiology Laboratories) Gunasekaran (2005) defined staining as the method of artificially producing color in microorganisms to allow for the visualization under the
