61 Exercise 12 Selected Biochemical Reactions Used to Identify the Physiological Characteristics of Bacteria (with special reference to Gram Negative Enteric Rods)
1 The Biochemical Activities of Bacteria Background Bacteria like all living organisms have the potential to undergo a wide variety of biochemical reactions in both anabolic and catabolic pathways.
In this lab, students identify an unknown bacteria using a biochemical method and a molecular method. ... systems. com) Product number 4336774 dNTP mix (10 mM) (10 µL) Invitrogen (www. invitrogen. com) Catalog number 18427-013 ExoSAP-IT (5 reactions) ...
Determining the Identity of two Unknown Bacteria U sing Tests to Explore F ermentative abilities, activity of enzymes, and biochemical reactions Section: 002 11/13/2009 Ryan Heasley
Additionally, culture media may also be differential, which allows groups of biochemically related bacteria to be distinguished from other groups of bacteria. This series of images illustrates some common biochemical media reactions for identifying bacteria.
Introductory Microbiology Lab Week 5 (October 4, 5, 6) Biochemical tests for identification of bacteria In this and next week's lab, you will be performing a set of tests to ... a very common reaction of many bacteria that reside in soils You will also inoculate four media that can detect multiple reactions: ...
MMBB255 Week 6 1 Biochemical and Metabolic Properties of Microbes I. Objective The goal of this ... based on its ability to produce proteins that allow it to carry out a set of unique reactions, its ... important in distinguishing among the members of the family Enterobacteriaceae (the enteric bacteria) .
Multiple tests were performed to provide the fermentation abilities, presence of certain enzymes, and certain biochemical reactions. Qualitative observations were made on the tests, which were compared to an unknown bacteria identification key to aid with the identification process.

L. acidophilus gave positive reactions with lactose, glucose, maltose, galactose sucrose and fructose and negative reactions ...
The biochemical reactions that take place can then be determined by relatively simple indicator reagents, included in the medium or added to the culture later. Some bacteria ferment carbohydrates, producing acidic, alcoholic, or gaseous end products.
