Ten of the unknown bacteria were classified as Gram-positive bacilli: Bacillus cereus‚ Bacillus circulans‚ Bacillus coagulans‚ Bacillus megaterium‚ Bacillus subtilis‚ Bacillus thuringiensis‚ Brevibacillus brevis‚ Geobacillus stereothermophilus‚ Lysinibacillus sphaericus‚ Clostridium perfringens. Lastly‚ there were also 11 Gram-positive cocci microbes: Enterococcus faecalis (Streptococcus)

The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria‚ Bacillus Subtilis. Introduction. One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly

The purpose of the lab was to test how temperature will affect the rate at which starch hydrolyzed. In the experiment conducted‚ bacterium; Bacillus Licheniformis and the fungus; Aspergillus Oryzae was used to examine how changes in temperature of the enzymes affects the rate of the reaction with starch. Amylase is an enzyme‚ found chiefly in saliva and pancreatic fluid‚ that converts starch

Dobrinka Atanasova Anthrax Anthrax is acute infectious disease that affects humans and other mammals. The causative agent of Anthrax is Bacillus anthracis. Bacillus anthrasic is a rod-shaped bacterium that forms spores (3). As we know‚ spores can survive many‚ many years in harsh conditions. Furthermore‚ the bacterium is also Gram-positive‚ encapsulated and aerobic (2). Anthrax can enter and affect the body via the skin‚ the lungs or gastrointestinal tract. The first one‚ the skin‚ is the least

It can also provide Vitamin K2. It prevents the establishment of pathogenic bacteria‚ and is associated with or found in the intestinal organ. The antibiotic that E. coli is resistant to is Penicillin. Bacillus subtilis—better known as B. subtilis—is known as the hay bacillus or the grass bacillus. It is gram and catalase positive. It is rod-shaped‚ with the ability to form a tough‚ protective‚ shield around itself. It can tolerate extreme environmental conditions‚ and is an obligate aerob. The antibiotic

Anthrax most commonly occurs in livestock‚ but it can also occur in humans when they are exposed to infected animals or to tissue from infected animals or when anthrax spores are used as a bioterrorist weapon.Anthrax is most common in agricultural regions where it occurs in animals. Although anthrax can be found globally‚ it is more often a risk in countries with less s98\standardized

In this instance a yellow sputum was produced by the patient‚ which will be taken to the lab an analyzed under a microscope. There are three suspect bacteria‚ which are Bacillus‚ Mycoplasma‚ and Escherichia. A discussion of staining procedures‚ as well as
