Introduction When we think of bacteria we don’t think of them as being a good thing especially when we think of Salmonella or Ecoli. It brings a sick feeling to your stomach or a cringe. But these microbes are being used for the greater good. Scientist are putting them to work. They are being genetically altered or medically laced to fight disease or to absorb lethal substances in the environment that contaminates our soil, water, and vegetation. If you can teach them or expose them to the appropriate environment they can be beneficial. Some might call this playing God while others may see it as a useful tool to put something there is an abundance of or is naturally occurring in a place where there is contamination and create a healthy …show more content…
There is hopes that some of the Mercury that has been filtered can then be recovered for later use in industrial technologies (Griggs, 2011).
Geobacter sulfurreducens
Geobacter Sulfurreducens is an obligate anaerobe, non-fermentative, non-motile comma-shaped rod, gram-negative bacteria commonly found in soil (Runge 2003). Mining for Uranium became a necessity during the Cold War but eventually we came to our senses The old Rifle Mill in Western Colorado was where The United States obtained its resources for uranium to help build nuclear bombs. Now that we have stopped trying to blow eachother up, the lasting effects still linger. Some microbes such as Geobacter sulfurreducens change uranium from its harmful form that can be dissolved in water to a form that will not dissolve. This allows it to settle out and be removed. Vinegar added to the soil containing the microbe helps it grow. The United States paid for research completed by The Department of Energy that tested this microbe. The research was conducted on wells, that were contaminated with Uranium, in the Old Rifle Uranium Mills. The tests were a success and the uranium levels were initially lowered by over 70%. Later tests showed the uranium levels were lowered by 90%. Besides lowering uranium levels, scientist isolated a specific gene of the Geobacter sulfurreducens that might help in creating a supermicrobe that may be used to clean up uranium sights around the world.
AIM – The aim of the experiment is to determine the relative effectiveness of several anti-microbial substances on developing pathogens. (E. coli)
Chapter 9 of the literature shows the spread of bacteria called E. Coli 0157:H7 as well as its negative effects. E. Coli 0157:H7 was found in the beef and 25 million pounds had already been eaten. The food poisoning was spreading rapidly and 200,000 people got sick. Schlosser claimed that since there is bad in the meat that is why people are getting an ill eating hamburger. Americans were getting afraid and constantly people were getting infected, especially children, elderly, and people with impaired immune systems. According to the literature,“...progressed to diarrhea that filled a hospital toilet with blood… drilling holes in his skull to relieve pressure, inserting tubes in his chest to keep him breathing, as Shia toxins destroyed his
2. Why do you think Mrs. Garner's students did not become ill, while Ms. Hines' kids did?
Escherichia Coli, located in one of the main organs known as the large intestine, is a type of bacteria that helps digestion. (Trzepacz, Timmons, and Duobinis-Gray, 2016) For Escherichia Coli to remain stable and alive, it needs specific necessities. These needs are known as the following: Energy, vitamins, and similar compounds. Escherichia Coli is found everywhere!

Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.
E.coli outbreaks have steadily grown over the last few decades. An expansion in big farming has led to E. coli not only being found in meat, but vegetation as well, due to waste runoff. This has increased our need for adequate antibiotics that can fight bacteria, like E. coli. The best way to pinpoint which antibiotics work is by measuring their ability to create antimicrobial agents or zones of inhibition. When a paper disc that has been saturated in an antibiotic is inserted in a solution of E.coli and medium, the zone of inhibition will be noted as the clear ring that forms around the disk. The antibiotics efficacy is then determined by measuring each disk zone of inhibition, and comparing these measurements to the zone measurements of an untreated specimen. If an antibiotic is to be deemed sufficient for treating E. coli it should show a zone of inhibition that is at least double the size of the untreated specimen.
we are curing disease. As we use antibiotics, the rapidly mutating microbes grow resistant. While
Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.
Rachel Carson was a scientist and author who took a topic which had hitherto been only of interest to fellow scientists and opened it up to the masses. During her lifetime, she took up many causes in support of wildlife and the protection of species and protecting the natural landscape from potential molestation from developers and others who would destroy indigenous habitats. Among her many missions was to make people aware of the hazards of certain chemicals on the environment, such as pesticides on vegetation as examined in her most famous work Silent Spring.
During our class discussion last week, we discussed Microbes Help Grow Better Crops, by Richard Conniff. In the article by Richard Conniff, he states that, “Adding bacteria to a crop to prevent human disease could be the start of a whole new path to food safety.” This statement by Richard Conniff explains to us the idea of preventing diseases by adding bacteria to a crop. As a result, we will be able to prevent most human diseases from existing in the first place. We as a society haven’t implemented the idea about adding bacteria to crops yet, but suggesting ideas that can help prevent problems for us as a whole is the first step to making our future better for us. Diseases such as, salmonella and E-coli can be prevented with the new understanding
In this lab experiment, students had to create a growth curve for E. coli. The E. coli growth curve would illustrate the progression of the population of E. coli a set time period. In this case, the growth curve depicted the population of E. coli over a 12-hour period. The growth curve for E. coli was created from the absorbance levels, the optical density(OD), recorded from the spectrophotometer.
Breaking news, 107 persons contacted Escherichia coli (E. coli) bacterial infection after visiting a petting zoo at a North Carolina County fair . . . a 2-year-old boy died.¹ E. coli bacterial infection is a growing concern for public health officials in the North Carolina Department of Health and Human Services and other local health departments. This is the most recent condition on E. coli outbreaks in North Carolina. In 2004, E. coli O157:H7 infection was responsible for making 108 visitors to the North Carolina State fair’s petting zoo ill.¹ This condition posed a serious health risk to the unsuspecting petting zoos’ patrons. Kids are more susceptible to these kinds of infections, because they are more prone to touching animals on display; then touching their mouths, noses, and eyes, which can lead to autoinfection. Most people are unaware of the infectious danger that lurks in the innocent coats of these cute furry creatures.
In 1945, Sam Walton opened his first variety store and in 1962, he opened his first Wal-Mart Discount City in Rogers, Arkansas. Now, Wal-Mart is expected to exceed “$200 billion a year in sales by 2002 (with current figures of) more than 100 million shoppers a week…(and as of 1999) it became the first (private-sector) company in the world to have more than one million employees.” Why? One reason is that Wal-Mart has continued “to lead the way in adopting cutting-edge technology to track how people shop, and to buy and deliver goods more efficiently and cheaply than any other rival.” Many examples exist throughout Wal-Mart’s history including its use of networks, satellite communication, UPC/barcode adoption and more. Much of the technology
