Maura Gongora 12th December‚ 2014 MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of

Mallory Charland February 9‚ 2015 Mutations of E. coli Lab Report Advanced Biology Deducing Mutations of the Lac Operon of E. coli Abstract: In this lab we determined a possible mutation in unique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)

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

Dr. GEORGE ROMBO Cholera This is an infection of the small intestine caused by bacterium vibrio cholera. Transmission is mostly from the fecal contamination of food and water that is caused by poor sanitation Susceptibility About 100 million bacteria must typically be ingested to cause cholera in a normal healthy adult. Children are also more susceptible with 2- 4 year old having the highest rates of infection Individual susceptibility to cholera is also affected by their blood type with

currently used to produce glutathione on an industrial scale. At the molecular level‚ the genes gshA and gshB‚ which encode the enzymes γglutamylcysteine synthetase and glutathione synthetase‚ respectively‚ have been cloned from Escherichia coli and over-expressed in E. coli‚ S. cerevisiae‚ and Lactococcus lactis. It is anticipated that‚ with the design and/or discovery of novel producers‚ the biotechnological production of glutathione will be further improved to expand the application range of

Factory Farming: Feast or Famine J.R. Phillips DeVry University Throughout history‚ human beings have grouped themselves together in communities. The concept of communities offered two major benefits; first‚ defense against enemies that might threaten the community. And second‚ the ability to sustain a constant food source to subsist on year-round. The need for a constant food supply became a major factor in early farming practices (Pollan‚ 2006) through animal husbandry

general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related to mechanisms of silver ion action on bacteria [110]‚ trypanosomes and yeasts‚ all of which can take up and concentrate silver (and copper)

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more
