Bacillus Essays

it is use in feed supplement farming that helps to promote animal growth as an alternative antibiotics. Bacillus subtilis can produce a variety of antimicrobial to compete other microorganisms by either killing them or reducing their growth rate. And subtilis also produce JAA that can be used against various crop diseases which can decrease significantly the

demonstrated that microorganisms are everywhere even in the air; the revolutionary germ theory was a reality.” After Pasteur did countless experiments, in 1864, he proved the germs were the cause of diseases. Later in 1876, Robert Koch identified bacillus bacterium was the cause of anthrax. This was the convincing evidence that proves the validity of the germ theory. Besides that, Koch also identified the microorganisms that cause tuberculosis and cholera. Therefore, the accuracy of germ theory is

What is Anthrax? This is a highly infectious disease caused by bacteria called Bacillus anthracis. It is found in the naturally in soil. This disease affects humans with the contamination of animal products. For instance the inhaling anthrax spores that have been inhalational anthrax or by consuming undercooked meat from infected animals. Although rare in the United states it is a deadly worldwide for instance in northern Europe. Humans get affected with anthrax when spores get into the body, one

frequency and rate of reaction decreases causing for a halt in product formation (Pitzer et.al., 2012). Thus, showing that enzymes need to be in their optimal environments to work properly. Bacillus lincheniformis and Aspergillus oryzae are both organisms that live that in medium temperature environments. Bacillus Linchenilormis has an optimal temperature of 45°C to 50°C, whereas

2.3 BACILLUS SPECIES The bacillus genus comprises of gram-positive aerobic or facultative anaerobic endospore-forming rod-shaped bacteria that includes both mesophiles and extremophiles (Priest, 1993). Bacillus species are ubiquitous and environmentally diverse, they include thermophilic, psychrophilic, acidophilic, alkalophilic and halophilic bacteria. The bacteria produce spores under unfavourable environmental conditions. Spores produced are resistant to heat, drying, disinfectants and other destructive

Introduction 1.1 Aim: To determine the kinetic parameters, Vmax and Km, of the alkaline phosphatase enzyme through the determination of the optimum pH and temperature. 1.2 Theory and Principles (General Background): Enzymes are highly specific protein catalysts that are utilised in chemical reactions in biological systems.1 Enzymes, being catalysts, decrease the activation energy required to convert substrates to products. They do this by attaching to the substrate to form an intermediate; the

study the biological importance of bacillus megaterium and to determine whether bacillus megaterium is susceptible or receptive to antibiotics by investigating the characteristics of the genus species and also. SUMMARY The purpose of this experiment is to be able to identify Bacillus megaterium using 16S PCR & Sequencing and also determine whether bacillus megaterium is susceptible or receptive to antibiotics using gram stain. Being able to determine whether bacillus megaterium is susceptible or receptive

could be separated, however, it actually took four plates to separate the bacteria. It was confirmed that both bacteria are gram positive. However, along with this one of my bacteria was not Staphylococcus. One being Bacillus was confirmed and actually both ended up being Bacillus species. It was thought that one bacteria would be catalase negative and the other catalase positive but they both were catalase positive. The hypothesis for oxidase was confirmed to be true and both were oxidase negative

Materials and methods Isolation and identification of Bacillus thuringiensis Bacillus thuringiensis was isolated from raw milk (Taif, KSA) on nutrient agar at 37oC for overnight. The supernatant of the bacterial isolate was screened for synthesis of AgNPs. The bacterial isolate was morphologically and biochemically characterized according to Bergy’s Manual of Systemic Bacteriology[21]. Also, this bacterial isolate was further identified by 16S rRNA sequencing. The culture was maintained on a nutrient

Bacillus subtilis is a commonly used organism in the biosynthesis of foreign gene products by recombinant DNA technology (Ohmura et al, 1984). Compared to other microorganisms Bacillus subtilis has several advantages including being non-pathogenic, well-known as an industrial organism and it can secrete proteins to the culture medium (Ohmura et al, 1984). Bacillus subtilis also contains the gene for the production of the enzyme α-amylase, which works to breakdown complex carbohydrates into simple

Bacillus Thuringiensis Cotton Genetically modified organisms are genetically engineered with DNA from viruses, bacteria, plants, and animals. Advantages of GMOs include: an increase in yield, a rapid growth of organism, a decrease in pesticide use, and creating the “perfect” organism. The disadvantages of genetically modified organisms are that there are unknown long term health effects of consuming GMOs for humans, and environmental hazards. Some common GMOs are corn, papaya, and cotton. According

Bacillus subtilis is a gram-positive rod-shaped bacteria that is often found in the soil and on various plant materials (Sietske de Boer and Diderichsen 1991). B. subtilis bacteria are seen as being non-pathogenic and safe toward human consumption, however, often times the bacteria are associated with another strain of microorganisms that have the ability to infect humans who have been exposed to immunosuppressive drugs (Sietske de Boer and Diderichsen 1991). Furthermore, B. subtilis has been found

A genetically modified organism (GMO) is an organism whose genome or genetic characteristics have been modified or changed by a technique known as genetic engineering so that its DNA contains one or more genes that do not occur naturally in the organism. The most common of all the GMOs are the genetically modified foods, which have sparked a widespread debate as to whether or not GMOs are beneficial or harmful to human health and the environment. The human population has developed more concern as

According to Funk & Wagnalls New World Encyclopedia, the U.S. Department of Agriculture carries out programs of research, education, conservation, forestry, marketing, credit, export expansion, food distribution, production adjustment, grading and inspection, and development of rural areas ("Agriculture, Department of."). Nearly 100,000 people make up twenty-nine different agencies within the USDA. These people do their part to participate in the agricultural act of eating that Wendell Berry talks

alter the genetic make-up of plants or animals is known as genetic modification. Scientists have shown the potential benefits that those genetically engineered crops can bring about such as increased shelf-life in Flavr Savr Tomato and pest-resistant Bacillus thuringiensis (Bt) corn, which are said to benefit the producers. From the consumers’ point of view, what matters most is the health benefits that genetically engineered crops will bring about, which wild-type food crops may not be able to do.

There are four types of social responsibilities and Monsanto using all of them in their company. These responsibilities can be arranged in a pyramid, with basic responsibilities closer to the bottom. Monsanto's economic responsibilities are making a profit mainly and staying committed to developing the technologies that enable farmers to produce more crops while conserving more of the natural resources that are essential to their success. Monsanto dominates the agricultural biotechnology industry

Jared Diamond Claim/Counterclaim Essay By: Trent Dickerson I have very mixed opinions on the statements of Jared Diamond and the Neolithic revolution. A way that I think it is bad is because it could have possibly caused overpopulation. A reason that I think it is good is because it allowed us to settle down in one place and have less people die from starvation. Another reason it was good was because it created the invention of agriculture. The one bad reason that I believe is bad about the Neolithic

CASES IN SUPPLY CHAIN ANALYTICS (BMGT44530) MEMO 2: PIONEER HI BRED INTERNATIONAL INC., STUDENT NAME: SHAILESH PANIGRAHY STUDENT NUMBER: 14200021 SUBMITTED ON 07 APRIL 2015 Introduction Pioneer Hi-Bred International, Inc a market leader in seed industry is headquartered in Des Moines, Iowa, USA. It produces and markets corn, soybean, sunflower, sorghum seeds, alfalfa, canola, wheat seed, silage and hay inoculants. Founded in the year 1926, the company has grown to become the largest seed producer

The reading states that several methods have been proposed to solve the problem of declining frog populations and provides three reasons of support. However, the professor states that these methods are not a practical solution and refutes each of the authors ' reasons. First, the reading states that if laws laws prohibited the farmers from using harmful pesticides, it would significiantly reduce the harm pesticides cause to frogs. The professor opposes this point by saying that this is not an economical

When people made a trip to the grocery store in 1994, few were expecting to see the Flavr Savr tomato, the first genetically modified food, on shelves for sale. Now, GMO’s are in almost every food we eat. Vegetables such as corn, squash, and alfalfa are the most common GMOs that are added to foods that people eat daily. Companies such as Monsanto, Syngenta, and Land o’ Lakes control much of the world’s seed supply and continue to push for GMOs to be in our foods. Jeffrey Smith, founder of the Institute
