Prokaryotic Cells: Observing Relative Bacteria Abundance and Diversity Author: Morgan Hain Email: Morganhain@tabor.edu Formal Lab Report for College Biology Laboratory BI110-G A Date: October 10, 2017 Abstract Bacteria are living microorganisms, that are in a group all by themselves. (Nordqvist, Christian. “What Is Bacteria? What Are Bacteria?” Medical News Today, MediLexicon International, Nov. 2016, www.medicalnewstoday.com/articles/157973.php.) This Laboratory Investigation focused on the presence of bacteria in student's environments. Each of the groups of students were given three agar plates, a sterile cotton swabs, and sterile water to sample their proposed area. When choosing the areas students had to have a hypothesis for the bacteria on the surfaces being tested. A sample of all the surfaces was taken with a cotton swab. Then gently rubbed onto the inside of the agar plate. The process had to be done quickly to ensure that the oxygen in the air was not entering into the bacteria. The plates were then stored at 32°C (90°F) for one week to allow the bacteria enough time to have growth. My lab Partner Kat Lohmeyer and I measured the different colonies formed in each sample, along with the different morphology types. Introduction Prokaryotic …show more content…

When we got the results for the snake tank the first time we got nothing. The bacteria did not grow. We must have done something wrong when putting the sample in the agar plate. What I think we did wrong was, we did not put enough of the sterile water on the cotton swab. We tested the turtle tank and the turtle with fish tank. And when we tested both our hypotheses help up. Both of us predicted that the fish with turtle tank would have the most bacteria. Our results showed that there was a more bacteria diversity on that agar plate. In figures 1.1-1.5 you can see the diversity throughout the

Introduction Our world is composed of many bacteria’s’ that can either help or destroy us. Therefore, its’s imperative to learn and study them. The purpose of the lab was to put into action the methods that have been learned in the laboratory to determine our unknown bacteria. Bacteria’s can have different features, shapes, and or arrangements that help microbiologist determined their role in our life (whether they are good or bad for humans).

The morphology of the bacteria is a rod shape. Through this experiment, it can be concluded that the bacteria is a Gram negative species. The selective and differential plates were left to incubate and after viewing the results, there was no growth on either of the plates. On the MAC plate, there is a bit of discoloration of the phenol red pH indicator. Though there was a bit of discoloration, it is not a strong enough indication that the bacteria reacted with the agar because there was no growth.

The plate was then properly labeled. To prepare the agar plates, 20ul of CaCl2 was added to a tube of top agar. Next, a tube of top agar was poured into a tube of M. foliorum and mixed gently. The mixture in the last step was then poured onto the L-agar plate where the “X” mark was made. After sitting for 10 minutes, the plate was incubated in the 30-degree Celsius incubator for 48 hours.

The experiment began by obtaining a sterile cotton swab and a petri dish and searching for a collection site in the Biology Department that would have bacteria. The unknown sample was collected at a recycling bin in Biology Building East. We swabbed the recycling bin using the sterile cotton swab and gently streaked the swab across the surface of the petri dish and immediately covered it with the lid. The petri dish was then placed in an incubator at 37C for two days. Two other petri dishes were obtained air and skin.

Unknown Microorganisms Lab Report

The purpose of this lab was to be able to classify unknown microorganisms from an outside source, as well as be able to use different staining techniques to view the organisms under the microscope. In order to do this experiment you will need to swab a source that may contain bacteria, yeast, or mold, and then transfer it to slides, using different techniques; then it is important to record your data and refer to a dichotomous key to help classify the microorganism. The results from colony 1 and 2 were relatively the same with both colonies cells containing uniformed sized bacteria with a cocci shape. Colony 3 contained chain like structures as well as a large size of 37.5um. This results lead to believe the unknown microorganisms were classified

Transformation was successful in the plates where the bacteria consumed the pGLO plasmid. In the first plate that the bacterium was plated on it included the LB broth and of ampicillin antibiotic (amp), 2 colonies were present. The second plate of bacteria was grown with the presence of LB broth, ampicillin, arabinose sugar (ara), and 22 colonies were observed. But a green fluorescent glow of the colonies was only present in plate 2. Plates 3 and 4 were the control plates.

subtilis. The next test on the key was whether or not the colonies were bright yellow. Since the colonies on the plate were in fact yellow, the conclusion that the bacteria must be Micrococcus luteus was made. According to Bergey’s Manual, this yellow pigment is a characteristic that is unique to Micrococcus in comparison to the other gram positive bacteria on the list. For the fourth and final test needed to further confirm that the gram negative bacteria was Micrococcus, the results from the MSA plate were examined.

Introduction: Microbiology is the study of the microbial world, which is composed of microorganisms that are too tiny to be seen with a naked eye. This project demonstrates the significance of correctly identifying unknown organisms with methods and techniques acquired in the laboratory as they can make or break one's ability to accurately isolate and identify various species. Studying microbes enables oneself to have an insight on not just their structure or how they function, but how they have an impact on organisms and their environment around them as they can be found nearly anywhere. The importance of the process of identifying unknown bacteria vary from determining the causative agent of a disease, to testing if a specific food or fluid is safe to consume, and simply knowing what is present

Master Plate Lab Report

The creation of the master plate was made up of specially selected bacteria from both experiment 3.2 and 4.1, the goal was to achieve a diverse selection of bacteria to observe closely at its texture, color, shaper, and margins. When selecting specific bacteria, I looked for the best combination of variation and choosing across all five of my plates for both agars. Through using morphological observation I was able to determine different bacteria such as colonies that are irregular and circular continuing with variations of elevations and edges. Also, the use of solid cultures such as the use of agar is rewarding because the bacteria will not move creating the ability to have many colonies on the plate while still being isolated and effectively

Bacteria is one of the first life forms that appeared on Earth, and that today lives essentially in all environments of the world whether an individual is aware or not. It takes many different shapes, but the most common are spiral, rod and spheres. Bacteria cannot be viewed with the naked eye; instead you need a microscope and are extremely small measuring in at 0.2um in diameter and 2-8 um in depth. In the science world bacteria is among the topics of controversy and many question if in fact bacteria is alive, or if it has life. At the end of the day bacteria will gain nutrients, reproduce and survive, making it a live organism and heartless when it comes to the people that it will cross.
