1. Title: The Process of Determining the Unknown Bacteria #9 Rachel Judecki July 5‚ 2011 2. Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification‚ the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol

Introduction This report will investigate the six essential nutrients required in our diet. The report will provide the function of each nutrient and explore why they are vital for the body. Carbohydrates Carbohydrates are the most important nutrient for the body as it is the largest possible source of energy. Carbohydrate supplies the body with energy‚ which allows the brain to function more effectively and allows organs to operate sufficiently. When the body has energy this allows each

Gut Bacteria In today’s world‚ many people have a very negative connotation when they hear the word “bacteria”. Bacteria have been the cause to many diseases‚ however bacteria do have some benefits and uses. There are thousands and thousands of different types of bacteria in the world and one group of bacteria‚ Gut Flora‚ has become evident in the bacterial community for being beneficial. Gut Flora is a group of bacteria that consists of microorganisms that live in the digestive tracts of animals

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 the zone of inhibition will increase because disinfectants are antimicrobial agents that are applied to non-living objects‚ and a petri dish is a nonliving

is researching a newly-discovered species of bacteria. At time t = 0 hours‚ he puts one hundred bacteria into what he has determined to be a favorable growth medium. Six hours later‚ he measures 450 bacteria. a. Assuming exponential growth‚ what is the growth constant "k" for the bacteria? (Round k to two decimal places.) b. After 10 hours‚ how many bacteria will there be? c. When will there be 10‚000 bacteria? 10. A certain type of bacteria‚ given a favorable growth medium‚ doubles in

The experimental data show that during the ten minutes of filtration‚ apple juice came out of the pectinase faster than the rest of the enzymes. During the last few minutes of observing‚ the apple sauce with pectinase was still producing apple juice‚ only slowing down a little bit‚ while the

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence
