Isolation and Identification Microbiology 521 2/10/12 Purpose: The purpose of this experiment was to enrich Pseudomonas bacteria‚ isolating a species of Pseudomonas and identifying it using phenotypic properties and DNA sequencing as an existent or completely new and undiscovered species of Pseudomonas. Overview: Genus Pseudomonas is a chemoheterotrophic bacteria found in soil and water. They are Gram negative‚ motile‚ paired rods that are also oxidase-positive. Pseudomonas species are

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

For an enzyme to act‚ there are a few factors that affect them which are: substrate concentration‚ temperature‚ salt concentration‚ pH‚ and inhibitors‚ activators and cofactors being present (Kumar‚ 2015) Finding the optimal temperature for amylase Bacteria and Fungi with the presence of starch is the purpose of this experiment. Optimal conditions are known as conditions in which organism are able to thrive in‚ where it is able to function at its best. If an organism was to surpass its optimal temperature
