Agar

cube with the largest Surface area will have the most molecules diffused into the agar cube because the more surface area a cube have, the more molecules the agar cube is getting per minute and thus the rate of diffusion will be faster. The experimental data show that the bigger is the surface area to volume ratio, the bigger is the percentage volume of diffusion, so the rate of diffusion of pigment from the agar cube. The result of this lab was that the block with the highest class average…

Then we also conducted the three in one experiment known as the SIM which stands for the Sulfide Indole Motility. In this experiment we prepared the agar by stabbing it with the microorganism and letting it grow. The results would tell us if our microorganism broke down certain amino acids and produces the byproducts and the growth out from the stabs to indicate the motility of the substance. After…

It is hypothesized that Bacteria X will create only narrow spectrum antibiotics. This will be tested by adding the bacteria to a small area on two agar plates – one plate with a gram negative ESKAPE pathogen and the other with a gram positive ESKAPE pathogen. If the bacteria grows on both plates and has a zone of clearance on both plates then it is likely that the bacteria is effective in broad spectrum…

from a virus that virus is called a bacteriophage. After a bacteriophage infects a bacteria it can create two different phases, the lytic or lysogenic cycles. During a lytic stage the bacteriophage causes death to the bacteria. When this happens on an agar plate covered in bacteria it creates a clear spot known as a plaque. Each plaque is created by one virus so from the number of plaques present it is possible to govern how many viruses are in a culture. During this lab this Plaque Counting…

The Lysine Iron Agar (LIA) black cap tube will be used to test decarbonation lysine, if positive for decarbonation it will have a purple slant and if negative it will be a darker red color. The LIA tube will also be used to test decarboxylate lysine, which will help us…

microorganisms, such as Gram-positive bacteria as well as Gram-negative bacilli. After the enrichment period, Brilliant Green Agar (BGA) was used as a selective medium for Salmonella, as microbes that are able to ferment lactose and sucrose will appear with yellow butt and slant, while Salmonella will appear red. Finally, the suspected Salmonella colony will then be inoculate in TSI and LIA agar slants in order to be confirm. TSI slants is a test that is use to distinguish microbes that ferments…

Even though, Agars use of incorporating examples of Hollywood distortion of human enhancement into his reading “Star Wars: Attack of the Clones and Star Trek: Nemesis”, (Agar 20) helps the audience understand what he’s talking about in a visual sense, creating relatability. replacing what he believes to be Hollywood’s misinforming with scientific…

case three test are essential to identify the unknown #63 and they are MAC agar test, BCP (lactose) broth and SIM deep medium/slant. Methods such as streak plate technique, aseptic technique, and proper handling of the microbe are necessary to apply when conducting these biochemical test. Contamination during the unknown lab project shows carelessness and may put patient in jeopardy due to incorrect result(80). The MAC agar plate that was stored in the incubator at 37°C for about 48 hours until…

the different types of motility arrangements were presented and why true motility helped microorganisms in their environment. Motility agar was used in this experiment and a needle saturated with the unknown microorganism was inserted straight into the agar. The following week it was found that there was no bacterial growth outside of the stab line in the agar which indicates the unknown as being nonmotile. The unknown microorganisms morphology and the arrangement were identified after…

outcome when testing for the sensitivity of microorganisms using antimicrobial agents. One of the biggest is the range of pH, which should be between 7.2-7.4 and have a thickness of 4mm. Another is the turbidity and the amount of organism placed onto the agar plate. All of these can have an adverse effect on the…
