The thought behind this series of experiments was to test a meat with many different forms that one encounters on a regular basis. The idea for turkey was chosen because it takes so many different forms it would be interesting to see the variation in microbial growth in the different conditions. Both experiments showed that although many think that raw meat would contain the most microbes, it’s actually deli meat that had more microbes than any other sample studied. The results that non-natural yielded more microbes than the organic turkey samples wasn’t as surprising, although some think that because organic meats are dipped in so many different concentrations to inhibit the growth of microbes there would be more microbial growth on the organic samples. It also became known that there is a wide array of microbes found on different samples of turkey in different conditions, although each one seemed to make sense that it would be associated with meat.

It was surprising that the deli meat had more microbes than the raw meats. We as a society know that eating raw meat poses serious health risks so for it’s microbial count to be lower than deli meat that we eat right out of the bag was extremely shocking and in a sense disturbing. Our predictions were far off with the first experiment as explained that we thought the raw meat would have the most growth. However, our predictions on the second experiment were spot on. We were correct that the sliced non-natural deli turkey was going to yield more microbes than the prepackaged meat or the organic deli turkey. This hypothesis was made because the deli turkey is going to come into contact with a meat slicer that may or may not have been cleaned in between cuttings which raises th...

...ent samples. Validity for the microbe count for the deli turkey in the first experiment can also be questioned. Due to three of four dilutions being deemed too many to count, only one number from dilution 4 could be counted and worked with, so the percentage of error can be significantly higher for the deli turkey sample.

A future experiment comparing different meats with turkey under different conditions would be interesting to observe. Meats such as ham, chicken roast beef along with turkey and comparing their microbial count might be an informal experiment as to which form of meat would contain the highest microbial count. The diversity of the different types of microbes and the comparison between the different meats would provide interesting information regarding the health benefits of the different types of meat that many of us consume on a daily basis.

Description of the Concept of the Microbial Loop Essay

- The concept of the microbial loop first began in 1926 by Vernadskii, who studied heterotrophic and phototrophic microbial metabolism; and understood that these systems represented a major part of total metabolism in the oceans (Pomeroy, 1988). Older techniques that scientists used for enumerating marine bacteria were by plate counts, serial dilutions and phase-contrast microscopy. These numbers represented about 10% of actual numbers and are no longer used (Azam et al, 1983). Scientists were unable to completely understand the microbial loop until recently when ultrafiltration techniques, applied electronic microscope techniques; and genomic techniques were developed to quantify biomass in...   [tags: marine bacteria, oceans, microbial loop]

How Does Mucus Affect Microbial Community Growth? Essay

- Many sediment invertebrates produce a mucoid secretion (Kristensen, 2000), which means most burrows have some form of mucus lining (Aller and Yingst, 1985, Nielsen et al., 2003, Mermillod-Blondin et al., 2004, Mermillod-Blondin et al., 2005, Webb and Eyre, 2004b). This secretion aids locomotion and burrowing activity (Bonar, 1972, Hannides et al., 2005), and stabilises sediment around invertebrate structures (Papaspyrou et al., 2005)(Nehring et al., 1990). As these secretions consist mostly of carbohydrates and proteins (Talmont and Fournet, 1990), mucus could be an important source of organic carbon and nitrogen in sediment environments and thus affect microbial community growth or activity...   [tags: Microbiology, Bacteria, Nitrogen, Oxygen]

Essay on An Era Of Variation And Economic Growth

- An era of variation and economic growth, the 1980s was the decade of consumerism and financial successes. Thus, the yuppie culture (Young Upwardly Mobile Professional Person) was born: comprising young self-indulgent, well-paid professionals, living an affluent lifestyle. Due to the expansion of the middle classes, materialism, style and technology were at the forefront: alongside a society controlled by popular culture and icons. The decade was determined by many factors including world events, politics, society, demographic and economic data, technological developments, influential icons, television, music and movies at the side of leading art and design movements....   [tags: Television, Popular culture, Third World, BBC]

Microbial Flora And Microbial Pathogenicity Essay

- Microbial flora & Microbial pathogenicity Microorganisms are crucial to the normal function and maintenance of the human body. Without said microorganisms, humans would not be able to live as they do now. They are involved in numerous vital processes which occur throughout a human being 's lifetime such as food metabolism, growth, the body 's immune response against some infectious agents and many others. The population of microorganisms that are present within and around a human being are present from birth, is unstable and is in a condition of continuous change which depends on a multitude of aspects such as age, food consumed and personal hygiene....   [tags: Bacteria, Immune system, Microbiology]

Essay on Identifying an Unknown Microbial Organism

- Identifying an Unknown Microbial Organism Introduction The purpose of identifying an unknown microbial agent is so that the five “I’s” of Microbiology, which are, Inoculation, Incubation, Isolation, Inspection and Identification can be practiced. Providing an unknown microbial agent tests the ability of ones skill of the above techniques and to accurately obtain the correct results and compare these results to biochemical test results that are already established.

Essay about Evolution of Microbial Resistance

- ... Other factors which have contributed towards resistance include incorrect diagnosis from doctors, leading to unnecessary prescriptions, improper use of antibiotics by patients, ant the use of antibiotics as a food additive for growth promotion in livestock. Recent research has demonstrated that bacterial protein LexA could be key in the acquisition of bacterial mutations. Microorganisms are able to protect themselves against antimicrobials in a few different ways. Many contain genes that encode proteins to neutralize effects of antimicrobials and stop attacks on the cell....   [tags: microorganisms and medicine, antibiotics]

Growth and Prosperity Essay

- Growth and Prosperity Growing older is something that is as inevitable as death. It is not up to us whether we will grow in age, but we can control how we embrace our never ending journey. As American anthropologist, educator, and writer, Loren Eiseley, once said “To grow is to gain, an enlargement of life…Yet it is also a departure. There is something lost that will not return.” Eiseley looked at life as a continuous advance, to make each day better then the last. He also notices that with every gain there is a lose, whether it be youth, innocence, or even lost moments....   [tags: Personal Growth]

Microbial Health of the Rhizosphere Essay

- Microbial Health of the Rhizosphere Works Cited Missing The importance of the interactions between microorganisms, plants and the rhizosphere was realized as early as 1904 by Soil Bacteriologist and Professor of Agronomy at the Technical College of Munich, Lorenz Hiltner. “The term rhizosphere was introduced by Hiltner in 1904.” (Gobran, 2001) Hiltner “emphasized the critical role of microbial activities in the ‘rhizosphere’ in the nutrition and general health of plants.” (Curl, 1986) The term rhizosphere was used to “describe specifically the interaction between bacteria and legume roots.” (Lynch, 1990) Today there is debate among microbiologists and plant scientists regarding the defin...   [tags: Biology Bacteria Science Essays Papers]
