    Christian Gram created the Gram stain technique in 1884 (K. Rudolph [Clemson University, Clemson, SC], personal communication). Gram used tissue in his first attempt with staining (1). The staining of the organisms allowed for the viewing of structure and determining those components by the viewing of the color that appeared after staining the organism (2). The purpose of this experiment was to identify the organism as gram-positive or gram-negative. The first step in the gram staining procedure

    Our results from the PCR process were very unexpected, even to the point the control colony had some rather odd outcomes. The goal of this experiment was to choose three colonies from the petri dish that has been exposed to +Amp, and look for any signs of the +Amp resistant gene, blaTEM, within the colonies and decide if this gene does have an impact on bacterial resistance towards the antibiotic. My partner and I decided to utilize a bacterial colony sample that does have blaTEM genes as our control

    This study was conducted with a partner, since some parts of the experiment were able to be done simultaneously. One partner prepared a TLC developing jar by pouring a small layer of 4:1:1 propanol/acetic acid/water into a developing jar. A solvent wick was made by wetting a piece of filter with the solvent, and it was placed in the jar. A silica coated TLC plate was obtained, and a spotting line was carefully drawn approximately 1.5 cm from the bottom of the plate using a pencil. Extra care was

    The first part of this lab was to get a chromatography, spinach and a quarter. The next step was to draw a line of the chromatography and rub the spinach leaf on it with the quarter. After this, the next step was to place the chromatography paper inside the tube and allow the solvent to rise to the paper. The final step was to remove the paper and mark the spots where the colors had shown up as they would disappear soon after. By doing this lab, it was possible to see all the different accessory

    macroscopic characteristics as a broth, so the first step was to Gram stain a loopful to determine the microscopic characteristics. Gram staining not only helped identify Unknown #10’s microscopic morphology but it also helped ensure the specimen was a pure culture—no other bacteria were visible when Unknown #10 was Gram stained and observed under the microscope. Unknown #10’s key microscopic morphology was that it was a very small, Gram negative bacillus. Though bacilli can possibly form endospores
