Determining the Unknown Microorganism from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by

providers work more efficiently. One of these medical advancements would be a mutated E. coli. So how exactly can a mutated E. coli be an advancement? Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes. To elaborate on how this altered bacteria works

An Ode to E. Coli There is a natural human tendency to dismiss what we cannot see. This idea is based in evolutionary biology. Throughout most of human history‚ threats to our survival have been deadly predators . It is only natural then‚ that we should focus our concern on objects whose importance we can see. For this reason bacteria seem insignificant on the surface‚ its invisibility marking its lack of precedence as a threat. This is a misconception‚ because bacteria hold enormous power. It can

The Effect of Acetyltransferases on 2 different strains of E. coli Introduction Scientists have recently discovered that resistance to antibiotics may not be such a new thing. Evidence of bacteria samples in Canadian permafrost proposes that these resistances have been around for at least 30‚000 years (Luiggi 2011). In our required pre-lab reading‚ we learned tuberculosis is becoming increasingly drug-resistant‚ giving proof that bacteria can adapt to necessary changes in order to survive (Barry

Student Lab Section 6 E. Coli Genetic Transformation with pGLO Plasmid Introduction: Genetic transformation is where one organism takes on a characteristic from another organism (Bacterial Transformation 2013). For this experiment we used the bacteria E. Coli to take in foreign jellyfish DNA which will allow it to change genetic material. This experiment determines the effects that the plasmid pGLO has in transferring the Green Florescent Protein found in a jellyfish into the bacteria. It

Title: E. Coli Transformation with a Plasmid DNA Containing the GFP Gene Introduction: Bacterial transformation is the process of bacteria taking in and expressing exogenous DNA. This has led to many other discoveries. In order for bacterial transformation to occur the bacteria must be in a certain physical state to be able to take in DNA. This is called competency and it allows the cell membrane to be permeable so DNA can pass through. Currently researchers are studying the transformation

Identification of Unknown Report Abstract: The purpose of this lab was to determine the identity of an unknown bacteria slant culture. The unknown was identified using differential tests to determine its metabolic and morphology characteristics. Results from the differential tests indicated that unknown culture 5 is Staphylococcus aureus.

This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant because they are not only beneficial but potentially hazardous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment
