Title: Observing Bacteria and Blood- Lab #1 Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides. Procedure: First, set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide

The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing
Introduction The primary goal of this lab was to notice the bacteria growth in each tube/plates and to be able to properly inoculated the media to get a good result. Materials • 4 Nutrient Broths • 4 Agar Slants • 4 Agar Deeps • 4 Petri Dish • 1 loop and needle • Bacillus subtilis, Escherichia coli, Staphylococcus aureus Samples Procedures 1. Label all of the tubes and petri dishes with the name of the bacteria and my lab partner and I initial, but leave one of each media as a control and label
Laboratory Report: Isolating & Identifying Bacteria Introduction: Through the conduction of numerous experiments, the identity of two bacterial isolates was determined. The tested specimen was an unknown sample of a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures that had been performed during
bacterial cells, then describe their morphology, observe and describe the primary features of the eukaryotic cell, and to investigate and observe the organisms involved in a symbiotic relationship. By observing these things, we are hoping to find out what we should expect to see in yogurt bacteria. In order to predict this, we must first know the differences between prokaryotic and eukaryotic cells. Prokaryotic cells are organisms that do not have a cell nucleus, or any other membrane-bound organelles
Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x, 40x, and 100x (oil immersion) objective lenses, which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge
Introduction Bacteria can be differentiated with specific metabolic activities. There are a variety of reagents and methods that can be used to distinguish species. The purpose of this experiment was to determine the characteristics of four different bacteria through four unique tests. The bacteria tested include: Escherichia coli (Ec), Pseudomonas aeruginosa (Pa), Bacillus subtilis (Bs) and Proteus vulgaris (Pv). Four types of tests were performed to understand the metabolic activities of the four
a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures and tests that had been performed during previous lab sessions. Each mixed culture that was tested had one gram positive and one gram negative bacterial species. The possible species of bacteria that could have been isolated from the mixtures
the lab we learned what bacteria are and the different types that can be found. Bacteria are single celled organisms that are the oldest life forms on Earth, dating back to 3.5 billion years ago. Bacteria are found in soil, water, and air, and on our bodies, plants and human made objects. Extremophiles are bacteria that can live in some of the most extreme environments on Earth. Bacteria grow in three different shapes: cocci (ball shaped), rod, and spiral. Beneficial bacteria aid in digestion, treat
October 26, 2015 Sydney Hartman BIO 115 Section CJ Sydney Hartman BIO 115- CJ October 26, 2015 Hypothesis: There is a bacteria in pond 22 that is killing the fish. Methods: In this experiment, results were found by discovering the kinds of bacteria found in the given pond water samples. The first step in this experiment was to prepare the pond samples by completing serial dilutions of the pond water to the 10-4. We then had to prepare five separate plates by streaking the 10-4 dilutes. These
