An obligate aerobe is an organism that needs oxygen to develop or mature. The organism can be a plant, a virus or a bacterium. It can only live in the presence of oxygen. Contrary to a facultative aerobe, which can live with or without the presence of oxygen. If oxygen is available in the environment, it will use it to grow, if not it will still grow, but the development will not be as fast as if oxygen is present.
Since a human skin was swabbed for S. Epidermis, a temperature of 37 degree Celsius is required for the growth. L. Acidophilus have a range of temperature but the ultimate one is 37 degree Celsius.
If both tubes are put under a range of temperature, the highest being 37 degree Celsius, what would be observe at each temperature change. In addition to the previous, have a set of cap tube tight as to let know air in. What would be observed?
Culture media can be found in different varieties of consistency and substance structure. There are three general forms of culture media: solid, semi-solid and liquid. The liquid form is usually refer to as broth. Culture media are nutrient preparations used to cultivate microorganisms such as bacteria.
An agar is a jellylike substance obtained from a red alga and used especially in culture media or to give firmness to foods. An agar slant is used to preserve bacteria cultures. It is put in a tube with cap, that way it does not become dry easily. The tube is then place on a rack. The agar slant take less space compare to the agar dishes. The agar dish is also called agar plate, mostly used to test sensitivity to antibiotics and to culture microorganism. There is also the agar stab, a needle is used to stab the culture deeply into the agar.
S. Epidermis: no noticeable change, probably due to less than 27 degree C. Temperature will be increase and monitoring continued.
First the product seems to have...

Mlt1 Task 2

...MLT1 TASK 2 Western Governor’s University April 02, 2015 Task: A. The difference between Facultative and Obligate aerobes is that while both aerobes require oxygen to survive facultative aerobes can survive with or without oxygen to survive. Obligate aerobes require oxygen to live and grow organisms, with facultative aerobes can grow live and grow organisms with or without oxygen depending on the certain conditions and organisms. B. According to labpaq (labpaq, received 2015) it stated it was very important to keep the temp at 37 degrees. 37 degrees is a prime temperature for S. epidermis and L. acidophilus bacteria that commonly live on the skin to grow. C. It is very important to control the growth of microbes one way to do this is with adequate aseptic technique. For example cleaning IV poles, blood pressure machines, stethoscopes using “sani wipes” or other disinfectants is appropriate. For proper aseptic technique in control growth on humans, I would use first and foremost proper hand washing, then things like iodine, alcohol, and hibicleanse. D. There are several forms of culture media. “Media can be either liquid (nutrient broth) or solid (agar).” (ScienceProf) “Very few forms of Microorganisms can degrade agar, so it usually remains in a solid form.” (Microbiology, Demystified, 2005) Agar slant puts the test tubes on its side to grow. Agar dishes are plates that lie flat to grow bacteria. “A culture made by inserting an inoculating nee...

...MLT1 Project Lisa Davidson Western Governors University May 17, 2015 MLT1 Project A. Difference Between an Obligate and Facultative Aerobe An obligate aerobe has to have oxygen to grow, while a facultative aerobe can survive with oxygen present or no oxygen present (Todar, 2012). B. Temperature Requirements and Types of Organisms The temperature requirement for this experiment is twenty-four degrees Celsius or above which is room temperature. The two types of organisms cultured are lactobacillus acidophilus and staphylococcus epidermidis. Lactobacillus acidophilus is a probiotic which is a live bacteria that is good for your health and found naturally in foods like yogurt. Staphylococcus epidermidis is a gram positive organism which is found naturally on our skin. C. Conditions Necessary to Control Microbe Growth In this experiment, microbe growth was controlled by providing access to oxygen, which was achieved by loosening the tops on the test tubes, and maintaining a constant temperature of twenty-four degree celsius or above. Also needed for the lactobacillus acidophilus to grow, was nine milliliters of MRS broth media. In order for the staphylococcus epidermidis to grow, five milliliters of nutrient broth was needed to house a cotton swab that was moistened and rubbed on skin. Microbial growth is not bad if it is a good microbe; however, certain microbes cause disease. This growth left uncontrolled can cause individuals to become sick or even die. To...

...Task two A. Describe the difference between an obligate and facultative aerobe. Obligate aerobe refers to the organisms that cannot survive in environments without any presence of oxygen. Facultative aerobes refer to the organisms that can survive in the presence of oxygen, but they do not require it to survive (Gillespie, Hawkey, & Wiley, 2006). B. Discuss the temperature requirements of the organisms in this lab. The temperature requirement of the organisms in this lab is approximately 37℃. These organisms require this optimum temperature for enzyme reactions to take place. Too low temperature below the optimum deactivates enzymes reactions while too high temperatures above optimum denature enzymes. S. cerevisiae, s. epidermis and l. acidophilus are facultative anaerobe (Gillespie, Hawkey, & Wiley, 2006). C. Discuss under what conditions you would want to control the growth of microbes. To grow bacteria in a laboratory the conditions in the lab needs to mimic the particular microbes natural environmental. To culture microbe’s sterile, disinfecting, aseptic techniques need to be used. For instance, aseptic techniques are also needed to transfer food to the microbe. Sterilization is a process of destroying all forms of life on an object or in a material including endospores. Disinfectant are chemicals which kill growing microbes, but not necessarily spore and are...

Aerobic and Anaerobic

...requirements. Some bacteria require oxygen; some can grow with or without it and some are actually killed by oxygen. Bacteria are generally classified into three main groups with respect to oxygen: 1. Obligate aerobes: Like humans, these organisms have an absolute requirement for oxygen. Because aerobic metabolism generates the toxic byproduct hydrogen peroxide, obligate aerobes must produce the enzyme catalase which breaks down hydrogen peroxide to water and oxygen gas. 2. Obligate anaerobes: Not only do these organisms not require oxygen, they are often killed in its presence. Because anaerobic metabolism does not generate hydrogen peroxide, obligate anaerobes generally do not produce catalase. The causative agent of botulism, Clostridium botulinum is an obligate anaerobe. Since the canning process removes the air, Clostridium botulinum can grow in inadequately sterilized canned foods. This isn't normally a problem in fresh foods since they are exposed to air. 3. Facultative anaerobes: These organisms will use oxygen in their metabolism if it is available, but can also grow without oxygen. Again, since aerobic metabolism generates hydrogen peroxide, they produce catalase. E. coli, which is normal flora of the intestine, is an example of a facultative anaerobe. In addition to these three basic categories of oxygen requirements, bacteria may also be classified as microaerophillic (requires oxygen, but can only tolerate limited amounts),......

Task 2

...Task Stream 2 Microbiology can be broken down into categorizations based upon the environmental conditions necessary for organisms in which to grow. Two large categories of microorganisms are those requiring oxygen to live (obligate aerobes) and those which can grow with oxygen but have the ability to also grow without it (facultative aerobes). The obligate aerobes produce more energy from nutrients than anaerobes by using oxygen as the “final electron acceptor in the electron transport chain, which produces most of the ATP in these organisms”(Betsy & Keogh, 2005, p.104). The facultative microorganisms are able to use oxygen but can also go without by using fermentation or anaerobic respiration when it is not available (Betsy & Keogh,2005). The microorganisms being cultured in our first task (Lactobacillus acidophilus and Staphylococcus epidermidis) are obligate aerobes. Microorganisms can grow in a variety of conditions with temperature being one of those variables, but the types we frequently encounter in our environment thrive in fairly warm temperatures. Both Lactobacillus acidophilus and Staphylococcus epidermidis are examples of these, which are referred to as mesophiles. Extreme temperatures (as in deep freezing or auotoclaves for example) are effective in destroying microorganisms due to their inability to thrive outside of more moderate temperatures). Growth of these two organisms would be optimized by remaining between 25 and 40 degrees celsius (Betsy...

Mirco Task 2

...Microbiology Task 2 Obligate aerobes are organisms that only grow when oxygen is present. Obligate aerobes get energy from aerobic respiration. Facultative aerobes are organisms that can live with or without oxygen present. I incubated L. acidopholis and S. epidermidis at 37C. The incubation sites should stay a consistent temperature for at least 24 hours. Mesophiles are bacteria that best grow in moderate temperatures (between 25-45C). Most bacteria are mesophiles. Mesophile bacteria could include soil bacteria and bacteria that live on or within the body. When you want to prevent the growth of microorganisms you would want to control the growth of microbes. For the transferring of organisms for this experiment I used aseptic technique which is preventing the growth of microbes. There are several methods of sterilization including heat, incineration, boiling, autoclaving, and dry heat. Heat is the most commonly used. Thirty minutes of boiling kills everything except some endospores. Autoclaving is steam under pressure and is good for sterilizing almost anything. Autoclaving kills everything, including endospores. Dry heat is only used for things that won’t melt and must remain dry. Pasteurization kills most vegetative bacterial cells and pathogens. Types of culture media include nutrient and bacterial growth medium. Nutrient media is the standard growth media used for culturing most microbes. Nutrient media is available in both liquid broth and......

A facultative aerobe can grow based on what is available and grow with or without oxygen. B. S. Epidermis is found on the skin and L. Acidophillus resides in the intestine. Both are a bacteria/microbe and grow best at normal human body temperature close to 37 degrees celsius. They are mesophiles due to their moderate range temperature requirements.. C. There are multiple times where controlling the growth of microbes is important. At home, you want to avoid growth of microorganisms in the kitchen and while cooking. This is why we boil water for sterilization and cook foods to specific temperatures in order to kill the bacteria. When dealing with raw meats we disinfect the sinks, counters and any area that is possibly contaminated. Antibacterial wipes and sprays are useful for this process. In healthcare, we are sure to use sterile technique when doing certain tasks as not to introduce infection to a patient. In surgical area, they may sterilize the instruments in a hot air oven. D. We use various forms of media for cultures including nutrient broth, agar slant, agar stab, and agar dishes. Nutrient broth is a liquid medium that does not use agar and is used for inoculum preparation. Agar dishes are sterile covered petri dishes filled with a solid medium in them, the agar, and used to test, grow and culture bacteria. For the agar......

Microbiology Lab-Bacterial Growth and Controlling It

...A. Describe the difference between an obligate and facultative aerobe. Obligate aerobes are bacteria that require oxygen for growth. They will only grow at the top portion of the culture media where it meets the air and has a lot of oxygen. Facultative aerobes grow based on what is available to it. They prefer oxygen but oxygen is not necessary for growth. These aerobes mainly cluster at the top of the culture media where they have a high concentration of oxygen but will dispersed throughout because they do not require oxygen. B. Discuss the temperature requirements of the organisms in this lab. 1. Explain what type of organisms they are. Staphylococcus epidermis and Lactobacillus acidophilus are both a bacteria microbe. They grow best at normal body temperature, close to 370C. Microorganisms are classified according to their preferred temperature ranges. Because both grew at 370C, they would be classified as mesophiles. Mesophiles grow best in moderate temperatures ranging between 250C – 450C (Alonzo, n.d.). C. Discuss under what conditions you would want to control the growth of microbes. 1. Explain what type of control you would employ in each situation. To minimize the risk of contamination from unwanted organisms, aseptic technique is required. In this experiment I washed my hands with antibacterial soap. I then place on gloves to prevent contamination to the cultures from the bacteria on my skin and to protect myself from unintended exposure of......

...Research: Thiobacillus Thiobacillus are small, Gram-negative, rod-shaped cells (0.3–0.5 × 0.9–4.0 µm). Some species are motile by means of polar flagella. No resting stages known. Energy is derived by the oxidation of one or more reduced sulfur compounds, including sulfides, sulfur, thiosulfate, polythionates, and thiocyanate. Sulfate is the end product of sulfur-compound oxidation, but sulfur, sulfite, and polythionates may be accumulated by most species, sometimes transiently. All species can fix carbon dioxide by means of the Benson–Calvin cycle and are capable of autotrophic growth; some species are obligate chemolithotrophic, (this means a bacterium that obtains its energy from inorganic compounds containing iron, nitrogen, or sulfur, and not from living on decaying organisms) while others are chemoorganotrophic. The genus currently includes obligate aerobes and facultative denitrifiers. Denitrifiers contribute to the nitrogen cycle which consists of the ongoing processes that Nitrogen has to undertake as it is the largest gas compound in the atmosphere. Their primary purpose being to metabolize nitrogenous compounds, with the assistance of the nitrate reductase enzyme, to turn oxides back to nitrogen gas or nitrous oxides for energy generation. The process of denitrification lowers the fertility rate of reproduction of the soil and thus is less common in areas where the land is rather well-cultivated. But this loss of nitrogen to the atmosphere can eventually be......

...oxygen requirements. The metabolic profile was created by inoculating the bacterium into broths containing glucose, lactose, mannitol, and citrate and incubating the tubes at 25° C for 48 hours, then observing it for color change. Oxidative metabolic tests for oxidase and catalase were also performed using an oxidative reagent and hydrogen peroxide, respectively. The Enterotube II System was used to further classify its metabolic profile. The stains revealed that the bacterium was a Gram-negative bacillus. The organism was shown to be non-motile and grows best at a pH of 10 and a temperature of 25° C, making it an alkaliphilic mesophile. The oxidation and fermentation tests showed that the organism is an oxidase-positive, catalase-positive aerobe that does not ferment sugars or metabolize citrate. The Enterotube II test results showed that the bacterium is not an Enterobacterium. In light of these attributes, the organism belongs in...
