bacterium was handed out by the lab instructor. The methods that have been learned so far in identifying bacteria were applied to this unknown. Procedures were followed as stated in the lab manual and biochemical test handouts. The first procedure that was done was a gram stain followed by a streak of the unknown on a TSA plate in order to determine the gram reaction and observe the colony morphology. After that‚ specific biochemical tests were performed for gram positive‚ since unknown number

microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of staining is the Gram Staining‚ as it is highly dependent (McCarthy‚ 25). In the specific experiment that was done‚ Gram Staining was

culture was performed on a Tryptic Soy Agar Plate for isolation and purity and then incubated at 37 degrees Celsius for 24 hours. A gram stain was performed to determine whether the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed when bubbles started

Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with
