Bacteria Essay

As described in Chapter 2, probiotics are known as the "good" bacteria found in our bodies. These living microorganisms are able to alter the body's bacterial colonies in order to generate health benefits on its host when given in proper amounts. These microorganisms can be beneficial because they are able to find a place inside the body's digestive tract and modify its ways of functioning. These actions, in turn, could possibly reduce digestive problems, such as colon cancer and ulcers.…

Bacteria may be the highest cause of death, but without their help in many aspects of life we would all be dead. Bacterium is a very important staple in everybody’s lives, and helps us with many things in everyday life including decomposition, digestion, and healing. Bacteria are very interesting creatures due to the shear force that they have even though they are microscopic in size, and do not have brains to guide them. Bacteria are everywhere and in every living organisms and help with many…

Gram positive: First, the bacteria sample is placed on a glass slide and heated only to the point of rendering it innocuous in terms of being infectious to the handler. Next, the bacteria sample is treated with a gentian violet-iodine solution for up to sixty seconds. The slide is then gently rinsed under clean water and the Gram solution is applied, which is a mixture of iodine and potassium iodide diluted in water. This step triggers a reaction to the gentian violet compound. Initially, the…

Experimental trials were performed by students over a timeframe of three weeks to determine the identity of three unknown bacteria contained in broth medium stored in labeled test tubes that were randomly assigned containing: one Gram positive bacterium, one Gram-negative paracolon, and one Gram-negative coliform (Carson, 2016). The unknown sample assigned in this experiment was #19. After initially streaking the solution on clean streak plates and TSA agar, the identity was determined from a…

Nitrogen-fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil. Let's break this concept down. Nitrogen is commonly found as an inert, or nonreactive, gas in the Earth's atmosphere. In fact, 78% of the Earth's atmosphere is nitrogen in its gaseous design. This element is so sufficient that it has been incorporated into all living things on Earth. In order for this to…

processes that bacteria use to survive. The key to their survival is their ability to genetically diversify. Bacterium diversity has had many years to develop. Bacteria were some of the first organisms on earth, and have developed many means through which they can adapt to changes in their environments. The first way bacteria can become genetically diverse is through mutations. A mutation is a process that changes a DNA sequence. This change can be passed on to future generations when the…

The killing and inhibiting of bacteria growth is with the help of Antibiotics Some people thought antibiotics are modern medicine; the truth is that it has been existing since several centuries. Antibiotics as many people know are gotten from natural sources. It is noted that since drug based antibiotics came into existence, natural antibiotic have been left to seat behind. It was recently noted that drug based antibiotic have huge side effects and it is regularly demanded in a high rate. Your…

Escherichia coli, a bacteria with an optimal pH of between 6.5 to 7.0 to enhance its proliferation is very commonly used in laboratories and studies worldwide due to its low cost and high effectiveness and will therefore be the bacteria of choice for this investigation. It has been shown in many studies such as the article “HdeB chaperone activity is coupled to its intrinsic dynamic properties” very recently published in the prestigious magazine Nature that bacterial growth and overall…

the disease it causes. At the beginning of class, the TA handed each student an agar plate containing some unknown bacteria, each one was numbered. Mine was number 14. The teacher then asked the students to use the techniques used in class (sterilize the inoculated loop, get a small amount of the unknown bacteria, incubate) to identify the unknown bacteria. To start, the unknown bacteria had to be successfully isolated. Using a wire loop, a small sample of the numbered test tube was plated on…

How Does Bacteria Gain Antibiotic Resistance? Antibiotic resistance can only occur when the bacteria changes in some way that reduces the effectiveness of drugs or chemicals designed to cure or prevent infections from further expanding in the body. With resistance, that’s exactly what these forms of bacteria are doing, multiplying and spreading or infecting others. The bacteria’s main goal is to survive and multiply in the environment they were introduced to so introducing an antibiotic will…
