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

organism you think it may be. That is why eighteen different tests are performed so that you can compare your results with the table of possible unknowns. 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

Anatomical Terms Certain terms are used to describe the location of body parts‚ regions of the body‚ and imaginary planes by which the body can be sectioned. You should become familiar with these terms before your study of anatomy and physiology begins. Anatomical terms are useful only if everyone has in mind the same position of the body and is using the same reference points. Therefore‚ we will assume that the body is in the anatomical position: standing erect‚ with face forward‚ arms at the sides

Microbiology Coursework: Bacillus cereus After investigation following on outbreak of food poisoning at a pizza restaurant‚ it was found that all suffers had consumed a portion of side salad from the self-service salad bar alongside their main dish. Subsequently‚ this was further traced to a rice salad. Environmental Health Officers investigating this outbreak suspected it may have been caused by Bacillus cereus (B. cereus). The presence of large numbers of B. cereus in a food is indicative

I had # 8 organism‚ Bacillus subtilis. Bacillus subtilis is a Gram-positive bacteria‚ rod-shaped and catalase positive. In order to figure out what is my unknown organism for this assignment‚ I had to perform series of tests. First was the glucose‚ lactose‚ and sucrose test. Through these three tests‚ I was able to detect the ability of the microorganism to ferment a specific carbohydrate. Fermentation reactions are observed by the color change in pH. In class‚ we used phenol red as the pH indicator

The Anatomical and Physical Features of Frogs Abstract: People have always wondered how frogs have the capability to live in both wet and dry environments. So why not dissect a frog to find out how. Frogs have both physical features like their skin that allows them to breath in water. They also have anatomical features like humans that allow them breath air just like us. Introduction As many people have learned throughout elementary and middle school amphibians are animals that have the
