\While taking organic chemistry, we performed a series of experiments involving compounds in which we extracted, purified, and isolated. This document is a lab report written on the recrystallization of compounds to purify of the compounds and removing its impurities. Recrystallization is used in areas of science to help obtain pure substances and growing crystal lattice. In the experiment, I recrystallized Benzoic acid.

Techniques for Growing & Testing Bacteria
Bio 3232: Microbiology
While taking Microbiology, we conducted a series of experiments that involved understanding and use of different techniques to grow and test Bacteria. To examine different microbes and bacteria, they must be grown on media that’s either solid or liquid. Using these media cultures allows the microbes to be supplied with the proper nutrients needed to thrive and grow. This lab lab report demonstrates my use of different test techniques such as Mannitol Salt Agar (MSA), Phenyl ethyl Alcohol Agar (PEA), MacConkey Agar (MAC), Eosin Methylene Blue Agar (EMB), and Nutrient Agar (NA Phenol Red Broth (lactose), Phenol Red Broth (Sucrose), Triple sugar ion Agar (TSI), Citrate Utilization Test, Catalase Test, Litmus Milk Medium, Methyl Red and Voges-Proskauer Test, and Urea Hydrolysis Broth Test.

Differentiation between Lab Staining Techniques
Bio 3232: Microbiology
In microbiology, we learned and practiced many different methods of staining to examin different bacteria. This lab report studied different staining techniques used to examine bacterial cells from microorganisms. The purpose of this lab report was to determine the best staining method to identify and characterize unknown bacteria. The different staining techniques explored in this lab report were simple stains, gram stains, negative stains, and endospore stains. The process of staining bacterial cells was used to visualize bacterial cells by color so that they could be seen through a microscope easier to determine items such as the arrangement of cells, morphology, and gram reaction. Different bacteria, such as E. coli and S. aureus, were used to perform each experiment. It was hypothesized that the gram stain would be the best method to view bacteria due to the fact that it is useful in distinguishing between two types of bacteria in one sample as well as . Before performing each stain, the specific bacteria used for the stain was grown in a test tube (broth) or petri dish (agar) using aseptic techniques. After each stain experiment was completed, the stained slide was then examined under a microscope using oil emersion to receive the best results. The results for each stain were recorded in tables showing the characters gathered from the stains. The findings from each stain showed that each stain was beneficial depending on the type of bacteria being examined. To learn more about the experiment, download the lab report below.
