Microorganism Essays

Microorganism - can cause illness and is hard to detect. Oxidation - what happens when oxygen meets other substances. Fungus - it is mold, yeast, and bacteria. Desiccation - when something loses water and dries up. If microorganisms get inside of the apple, they cause food decay and develop unpleasant odors, tastes, and textures. Apples turn brown because of a chemical process called oxidation, this happens when oxygen interacts with another substance. Fungus

3. Introduction Microorganisms are microscopic organisms that can be found all around us. They cannot be seen with a naked eye, but can be viewed with the use of a microscope. Microorganisms occupy a wide range of environments. They can be harmful or beneficial. We can classify microorganisms into 4 main groups namely Viruses, Bacteria, Protista and Fungi. In this investigation we are going to focus on the microorganism Bacteria. This investigation investigates whether a dirty potato in favorable

examinations (learned throughout the semester), critical thinking, and application of that knowledge to identify an unknown bacterium from a mixed culture. This report covers the logical progression used to identify Unknown 15, the isolated microorganism. Handling of microorganisms in the lab requires the use of aseptic technique to establish pure cultures and to protect against environmental contamination. Pure culture contains a single

identify an unknown microorganism by performing a series of biochemical tests on a pure bacterial culture. Materials and Methods: Tests: Lactose fermentation: Fermentation makes energy available for use by microorganisms by anaerobic breakdown of carbohydrates. The product can either be an acid or gas. When it is positive, the broth will turn from red to yellow and if gas is present a bubble is formed.  Sucrose fermentation: This fermentation makes energy available for use by microorganisms by anaerobic

microbial species has a combination of morphological and metabolic characteristics. A series of biochemical test need to be carried out on an isolated culture of the unknown microbe. These tests will assess the metabolic properties of the unknown microorganism. Using the unique combination of characteristic determined by the series of tests, the unknown microbial species can be identified. Specialized cultural medium are used to isolate and identify particular organisms, such medium are called Selective

In this experiment, we cultivated an unknown specimen containing two microorganisms. The purpose of this experiment was to use a variety of biochemical test previously learned in the lab to identify the unknown bacteria. The identification of unknown bacteria is a major part of microbiology. Microbiologist observe samples such as blood and sputum in the laboratory for the presence of microorganisms. Identifying unknown bacteria is extremely important in clinical settings because it helps physicians

degree of compactness in the distal gut. The microorganisms of the distal gut outnumber the entire amount of human cells by an incredibly large amount. Given that the gut microbiota serves a vital function in the human body it qualifies to be considered an organ specific to humans. Two of the main functions that the gut microbiota are responsible for are to generate ATP from nutrients and to regulate the human immune system. Changes in the normal microorganisms in the distal gut may result in disease

paper beats rock. When any two of the competitors face off, one outcompetes the other. However, when all three competitors are in play, they all survive. This same type of competition can be observed between organisms in an ecosystem and even microorganisms in a petri dish. This experiment was carried out to observe the effect of Gram positive

7.1 Microbial Nutrition The process by which microorganism acquire the nutrients from their environment and use them in metabolism and growth is called nutrition. There is not much difference in the nutrition of humans and microorganisms. All living things require a source of element like sulfur, carbon, oxygen, etc. There are some essential nutrients, those are the elements that must be provided to the organisms. Some those are required in large quantity called macronutrients and some are required

emerging need to remove the cadmium from the environment. Microbes are very helpful in this area to remediate the cadmium from the environment. Microorganisms used biotransformation and adsorption mechanisms for regulation of translocation of heavy metals. In present time, many research has been done on the toxicity of cadmium in microorganisms. Microorganisms release many types of organic and inorganic substances by which they can detoxify

extent of environmental resistome and its mobilization into pathogenic bacteria is essential for the management and discovery of antibiotics. INTRODUCTION Antibiotics are organic substances produced by microorganisms, capable of inhibiting the growth or destroying another microorganism at low concentrations [1]. The antibiotics field was initiated when Paul Ehrlich first coined the term ‘magic bullet’, or chemotherapy, to designate the use of antimicrobial compounds to treat microbial infections

What does FAT TOM stand for? What are some of the factors that allow food microorganisms grow? The acronym "FAT TOM" stands for food, acidity, time, temperature, oxygen and moisture. This acronym is used in the food service industry to describe the conditions that contribute to the different types of food-borne illnesses. Food - There are the sufficient amount of nutrients available to promote the growth of microorganisms. The most susceptible are Protein-rich foods such as meat, milk, eggs and

Introduction Propionibacterium acnes or former Corynebacterium parvum is an important bacterial agent which acts as a multifunctional microorganism. This bacterium is seen in different parts of the human body; from conjunctivae, oral cavity, and nares to intestinal and respiratory tracts. The biochemical properties of P.acnes are related to the bacterial functions and activities. This bacterium is a slow growing Gram +ive, anaerobic and microaerophilic bacillus which is able to produce propionic

actic acid bacteria: one of the most important group of microorganism its associated with plants, meats , and dairy. lactic acid produced from carbohydrates and sugars. its also consider a strong fertilizer and harmful microorganism. one of lactic acid benefits are empowering the productions of important sources of energy in your body which are glucose and glycogen in the liver. so therefore it helps gain energy. also helps in losing weight lactic acid makes a fast process of dietary carbohydrate

vital to distinguish the identities of microorganisms in the world. Knowing their identity has aided in diagnosing numerous diseases and has discovered the most beneficial treatment. Lately, it has been vital to differentiate the identities of microorganisms worldwide. Recognizing their identity has aided in diagnosis numerous diseases and has discovered the most beneficial treatment. To study in microbiology, it is crucial for us to use microscope for microorganism observation. The microscope is an

mankind’s greatest scientists. Louis Pasteur saved many businesses that used milk, wine, and beer. He thought that a microorganism was in the large vats that the manufacturers used. He thought that because the vats were never cleaned, bacteria was getting into the liquid, and making it spoil. He thought that if he heated it up enough, he could kill the microorganism and still preserve the product. He called it the pasteurization process. Many companies today still use his process to make their

A microorganism is a small individual life form. The first microorganism was discovered in 1673 by Antonie Van Leeuwenhoek. He observed the first single celled organism with his microscope. Previously, the existence of microscopic single celled organisms were unknown. In 1854, Louis Pasteur discovered microorganisms that change sugar to lactic acid, causing his wine to spoil. He then developed the process now

Disinfection Chemicals Introduction Water disinfection is removal, deactivation or elimination of pathogenic bacteria. Bacteria gets damaged or even deactivated, disabling reproduction. Disinfectants must not just eliminate bacteria. They must have residual effect. The disinfectant must not allow pathogenic bacteria to develop within the domestic plumbing after disinfection, causing water being decontaminated. Chemical disinfection of water the uses following disinfectants. Chlorine, Chlorine dioxide

Microorganism is living organism( such as bacteria, fungi, viruses) too small to be seen with naked eye but visible under a microscope. Also called But as long as humans microbe(Dictionary.com)can’t live without carbon, nitrogen, protection from disease and the ability to fully digest their food, they can’t live without bacteria, said Anne Maczulak , a microbiologist and author of the book “Allies and Enemies: How the World Depends on Bacteria”(FT Press,2010) Microorganisms are crucial because they

symptoms (3,4). Enterobacter, Serratia, Escherichia, Klebsiella, Proteus, and Citrobacter are altogether included of Gram-negative genera of the normal intestinal flora (3). If a human will constantly eat or drink any contact with food spoilage microorganisms, they will most likely be capable of gastroenteritis. The severe gastroenteritis will digest the contaminated food approximately up to 24 hours (3). E. cloacae can grow at temperature 25C and body temperature optimal 37C (5). “E. cloacae has
