Escherichia coli

positive and not in the gram negative. Chemical composition of Gram negative includes lipopolysaccharide, lipoporteins and peptoglycan while Gram positive includes petidoglycan, teichoic acid and lipoteichoic acid. Examples of gram negative include E coli and Gram positive S. aureus. SIMILARITIES OF GRAM NEGATIVE AND GRAM POSITIVE BACTERIUM There are not many similarities between the gram negative and gram positive. They both have the peptidoglycan surrounding the periplasmic space. The both…

Purpose: The overall goal of this lab was to perform a procedure on E. Coli which involved transferring genes that encoded for the green fluorescent protein into E. Coli to see if the transferred genes would make a difference on the growth and whether or not the bacteria would glow under UV light. Hypothesis: If the bacteria with the pGLO plasmid was grown on a plate containing LB and ampicillin then the bacteria will grow but not glow under UV light. If the bacteria with the pGLO plasmid was…

Think Like a Freak “Like a Bad Dye Job, the Truth Is in the Roots” Jayla Helton ECON 202 Summary In this chapter, they discuss how people discover a problem, and try to find a new way to approach it. The causes of many diseases, are still unknown to this day. Through several resource and trial and error, doctors have still never found a cure to some diseases. Finding the roots to and issue can sometimes to be difficult. A small section of this chapter talks about the economy…

General Information Klebsiella Pneumoniae is a "Super-bug". "Super-bug" is a term used to describe strains of bacteria that have become resistant to the majority of antibiotics that the medical community prescribes today. These superbugs can cause a range of diseases, depending on which part of the body they infect. Klebsiella pneumoniae is a bacteria which is found inside human intestines, where under normal conditions it is not known to cause disease. However, Klebsiella pneumoniae has…

Symptoms of Candida Overproduction and Treatment The fungus Candida is a form of yeast found in your intestine and mouth in small amounts. The function of this fungus is to help the process of digestion and absorption of nutrients. However, overgrowth of Candida causes the fungus to enter the blood by breaking down the intestine wall. It releases toxic byproducts causing digestive issues, leaky gut and depression. How does Candida overgrowth happen? The bacterium in the gut that is not…

Assessment of enzyme producing efficiencies of endophytic fungi Extracellular enzymes assay was conducted to investigate the production of enzymes by the endophytic fungi Amylase activity Amylase enzyme was assessed by growing the fungi on glucose yeast extract peptone (GYP) agar medium (glucose- 1g, yeast extract- 0.1g, agar- 15 g, distilled water 1000mL and pH 6) containing 1 % soluble starch after 5 days incubation , the plates with fungal colony were flooded with 1% iodine and 2% potassium…

many types of food they consume. Meat Inspection Act in 1906 followed by the Pure Food and Drug Act would also be passed for the same reason as the Pure Food and Drug Act. But recently, major foodborne outbreaks would happen such as salmonella, E. coli, and listeria. These outbreaks have tripled in the United States in the past twenty years (Newsela). All these foodborne outbreaks would be included in poultry, vegetables, fruits, and beef (Newsela). A incident that happened would…

LO 2.1 I understand that free energy, the portion of a biological system’s that can perform work when temperature and pressure are uniform throughout the system, is used in systems to cause change. I also understand that empirical data proves all organisms require a constant energy output to maintain organization, to grow, and to reproduce. (Campbell 119-123) LO 2.2 I understand that although free energy is always required in living systems in order to maintain organization, to grow, and to…

Introduction The human body is populated by a large aggregate of microbes on the skin as well as many mucosal surfaces. They are composed of mainly bacteria, fungi, and protozoa. These commensal microorganisms live in the human body in symbiosis. Microbiota play a functional role in the health and disease of an individual. Roughly there are around 1012 bacteria found on the skin, primarily staphylococci and corynebacteria, and 1010 found in the mouth, primarily, streptococci, lactobacilli.1 But…

Deinococcus radiodurans (D. radiodurans) was discovered in 1956 by Arthur W. Anderson at the Oregon Agricultural Experiment Station in Corvallis, Oregon. There was an experiment to determine if processed foods can be sanitized by using great amount of gamma radiation. A can of meat was revealed that radiation, which was believed to destroy all known types of lifestyle, has been damaged and D. radiodurans was separated. D. radiodurans is known for its radiation-resistant qualities. Being that it…
