Bacillus Cereus Bacillus cereus is a rod-shaped gram- positive bacillus that can be found in food‚ dust‚ dirt and sometimes soil. It is an aerobe and a facultative anaerobe that can form spores‚ which if activated at any point can begin to germinate and produce toxins. These spores that form from B. cereus are be resistant to heat and chemicals. B. cereus is found in approximately 25% of food sampled (3). Foods that are commonly associated with B. cereus are potatoes‚ rice‚ meat‚ vegetables

5) My hypothesis: “The higher the concentration of antiseptic‚ the more powerful it will be at inhibiting/ killing microorganisms which cause bacterial growth.” This theory supports my result because as you can see the zone of inhibition increases due to the increasing concentration of antiseptic. The higher concentration of antiseptic means it has been less diluted‚ which means its more stronger than other more diluted concentrations‚ this high concentration will determine how powerful the antiseptic

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

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone

themselves to substrate molecules and lowering the activation energy of a reaction (Alberts et.al‚ 2010 p.90). 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

Bacillus‚ Mycoplasma‚ and Escherichia In a clinical setting signs and symptoms can lead a care taker down a treatment path‚ but if a bacterial infection is suspected‚ a definitive answer from the “lab” is needed before prescribing medications. 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

antiseptics (Hydrogen Peroxide)‚ disinfectants (Ammonia)‚ or antibiotics (Erythromycin) are the most effective; in other words‚ which type of bacterial inhibitor will create the largest zone of inhibition in millimeters squared. In doing this experiment‚ the researchers will reveal which bacterial inhibitors abolish the most bacteria. In the future‚ people will choose the most effective bacterial inhibitor; therefore‚ they save both money and time. If the disinfectants are applied to the bacteria‚ then
