1. Title: Double unknown identification of a mixed culture of Gram-negative and Gram-positive bacteria 2. Author: Nick Fiore‚ University of Kansas‚ Biology 402‚ Fall 2014 3:00pm room 6040 3. Abstract: The purpose of this experiment was to isolate two unknown bacteria and perform a series of selective and differential tests to correctly identify each. After the bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria

kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However‚ because new strains continue to emerge‚ it is of the utmost importance that microbiologists and microbiology students understand the nature of each bacterial species and how that species creates and maintains its complex communities.

Introduction The science of microbiology is all about microorganisms‚ what they do and how they work. Microorganisms are ubiquitous‚ and are a very important part of life everywhere since they have been around for billions of years. The two main themes associated with microbiology are (1) having an understanding of the nature and function of the microbial world‚ and (2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6).

Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion‚ when we pour ethanol over the slide to wash away the dye then only definite bacteria can retain
