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

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations

Microbiology is the branch of Biology that deals with the study of microorganisms and how they influence or work with other living organisms. (Satellite Events Enterprises Inc.‚ 1999) In this paper I will discuss the history of Microbiology and specifically the early theory of spontaneous generation. I will discuss three spontaneous generation experiments and explain why it is obsolete in today’s science. History of Microbiology Since Microbiology is the study of microorganisms‚ it is understandable
