Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X

bacterial growth‚ this experiment focuses on the Monod equations. However‚ in order to use the Monod equations‚ the maximum growth rate and Monod constant must be found. Here we show how the maximum growth rate and Monod constants can be obtained for Escherichia coli using M9 media in a bioreactor at 37 °C and 500 RPM. The maximum growth rate is also obtained at other settings to show how other factors can affect bacterial growth. The maximum growth rate and Monod constants for E. coli with these settings

In late 2015‚ two outbreaks appeared in America. In the first‚ larger outbreak‚ 55 people infected with Escherichia coli O26 (STEC O26). 55 people are from 11states. 21 ill people were hospitalized. In the second outbreak‚ 5 people from 2 states infected with STEC O26 and 1 people was hospitalized (CDC‚ 2016). FDA along with CDC and local public health official investigated two outbreaks and found that most of the victims ate Chipotle Mexican Grill before. They think two outbreaks may relate to Chipotle

The Center for Disease control has estimated that illnesses directly resulting from food contamination cause approximately 76 million illnesses‚ 325‚000 hospitalizations‚ and 5‚000 deaths each year in the United States. The rise of food-related illnesses can be mostly attributed to increased eating out. Half of every dollar spent on food in this country is spend on food prepared outside of the home. As the amount of people involved preparing our food rises‚ so does the risk of contracting an illness

November 25‚ 2012 The Effect of the pGLO Plasmid on Genetic Transformation of E.coli by Heat Shock Introduction Genetic transformation is the genetic alteration of a cell resulting from the direct uptake‚ incorporation and expression of exogenous genetic material l(exogenous DNA) from its surroundings and taken up through the cell membranes. This was first demonstrated in 1928 by Bacteriologist Frederick Griffith (Lederberg 2000).A plasmid is a small circular piece of DNA that contains important

Testing method – In this method‚ the team will get sample to be tested for E. coli or Escherichia coli and Staphylococcus aureus. E. Coli normally lives in the intestines‚ where it helps the body break down and digest the food you eat. Unfortunately‚ certain types (called strains) of E. Cole can get from the intestines into the blood. This is

The E.coli bacterial cell was used in order to observe how its DNA was able to change and develop immunity towards ampicillin. In order for this change to occur the use of several
