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

In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

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

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

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

The Figure 4.20 shows the profile growth of Escherichia coli type K-12 which was cultured in 20 g/L of glycerol treated with supplements from a carbon source under anaerobic condition and the medium supplemented with 10 g/L of trypton. About 10% working volume of inoculums were added to the medium for the profile growth process. The effects on growth curves of strains of Escherichia coli were investigated by measuring the concentration of succinic acid produced and its optical density by using HPLC

INTRODUCTION Bacillus anthracis has recently become popular as the causative agent of anthrax infections. Belonging to the bacillus species‚ the bacterium is considered‚ along with Bacillus cereus‚ to be of extreme medical importance. Until recently‚ the condition caused by the bacterium was rarely heard of. Although the bacterium is naturally found in the soil‚ its rare occurrences in humans have only been observed in those working with livestock or imported livestock products‚ therefore the

My unknown bacterium after performing the tests and comparing the charts is identified as Bacillus cereus. Bacillus cereus is a bacterium that grows best around 30-37°C. B. cereus cannot grow in high acidic‚ below pH of 4.5‚ or high alkaline environments of a pH above 9.3. You are likely to find this organism in the soil. This bacterium is able to form
