Eukaryotic Growth Lab Report

Abstract This experiment was constructed to distinguish the differences with Prokaryotes and Eukaryotes by growing through a variety of media. These media consisted of rich and minimal. Rich media is a media that contains an abundant supply of nutrients for bacteria to grow. Minimal media is a media that contains the minimal amount of nutrients for bacteria to grow. Medias are important because they not only are used in growing microorganisms but are used in the medical field to help with the treatment of viruses. For Prokaryotes growth we oversaw the growth of Vibrio natriegens for 2 hours and collected samples every 10 minutes in order to determine growth through turbidity and viable cell counts. For Eukaryotes growth, we looked at Saccharomyces …show more content…
By conducting this experiment, we concluded that the longer we left the bacterium Vibrio natriegens colonizing, the more CFU/mL we observed. The plots represent time points during our experiment in which we recorded the CFU/mL for that allotted time. The intervals in which we recorded information were set for every 10 minutes.

Eukaryotic Growth.
Through this experiment we were able to conclude that as the longer S. cerevisiae was let to colonize in the minimal media, the more cells/mL were found. This is clearly shown in the table demonstrating the number of plate counts that were found. Each plot on the table represents an allotted hour that we took a recorded measurement of the cell growth. Time points were designated for every 4 hours.

1.2 Prokaryotic Optical Density

Figure 2:
Prokaryotic Optical Density (600nm).
For the prokaryotic growth, optical density increased in a linear fashion as the time increased. The plots represent time intervals of 10 minutes recorded throughout the experiment to help determine the optical density of Vibrio natriegens over a time of 120 minutes.

    Abstract: The effect of incubation with white rot fungi on improvement of the nutritive value of bagasse was evaluated. Bagasse was either autoclaved at 120˚C for 20 minutes or steam pasteurized at 100˚C for 1hour and inoculated with Pleurotus Ostreatus or Pleurotus Citrinopileatus at the rate of 2% (w/w). Incubation period was 0, 50, 85 and 120 days. Nutritive value was determined by enzymatic analysis. By 120 days, the proportion of OCC and Oa increased by up to 44.0% and 77.5%, respectively (when compared with raw bagasse).…

    The EMS treatment was performed until 99.9% of the E.coli cells were killed, as this was the peak time that the ideal amount of mutagenesis was achieved and minimum number of multiple mutations in a cell. We followed the protocol as described in page 14-17 of the lab manual. However even though mutagenesis was achieved through EMS treatment, we would have to screen 100-1000 plates to isolate one mutant, therefore in part II of the experiment penicillin enrichment was used. We calculated that 10 µg of ampicillin would be added to the culture of mutagenised cells. The rest of the experiment was conducted as stated in the lab manual following part III onwards to part VIII, we screened for any biosynthetic auxotrophic mutants, picked cells from the mutant colonies, created pure mutant cultures and finally we identified the specific nutritional requirement of each of the mutants we obtained.…

    Our goal within the plasmid isolation lab was to isolate the bacterial plasmid without any damage to the DNA. The formation of the clear lysate was essential because it allowed us to isolate the bacterial cells from removed media and later expose the DNA. Resuspension solution helped to resuspend the cells, after centrifugation, and prepare the cells for lysis solution. The lysis solution functions to degrade the cell membrane and spill its components. Then the Alkaline Protease functioned as the inhibitor of any DNases and denatured dsDNA to ssDNA shortly, by disturbing H-bonds between bases.…

    The homogenate was centrifuged at 16,000 rpm for 15 min at 4°C (Karthikeyan et al., 2005). The supernatant served as source of enzyme for peroxidase assay. The reaction mixture consisted of 2.1 ml distilled water, 0.32 ml 100 mM potassium phosphate buffer (pH 6), 0.32 ml 5% freshly prepared pyrogallol solution, and 0.16 ml 0.5 % H2O2. Reaction mixture was mixed properly and incubated at room temperature for 10 minutes. Optical density of mixture duplicate was measured at 420 nm in a spectrophotometer (UV-Visible Spectrophotometer, Shimadzu, Japan).…

    Making it a long process that produces 700 base pairs (bp) in an hour. In the other hand, Next Generation involves shorter steps, it amplifies the genome fragment by PCR and then determine the sequence by observing the addition of nucleotides as it is synthesized from the template. Also, most of the steps are performed by machine. A major difference between Sanger and Next Generation Sequencing is the read length produce, Next Generation produces 75 to 400 bp between 7 hours to 10 days and there is more analysis to do on Next Generation than Sanger. This technology is comprised of various platforms which include nanopore technology, Illumina and Roche/454.…

    In vertical transmission, mutations in bacteria lead to mass antibiotic resistance in a colony. Penicillin works be disabling the assembly of the bacterium’s cell wall, causing it to become weak and eventually burst. Some bacteria, however, do not replicate correctly. If a bacterium if formed that carries a mutated gene that allows it to neutralize the effects of Penicillin, this mutated bacterium will most likely be one of the few to survive a Penicillin attack. Therefore, it will be one of the only ones available to reproduce and pass on its traits.…

    THP-1 cells and THP-1 cell culture methodology were also provided by Ondek Pty Ltd. THP-1 cells were cultured in RPMI-10 culture medium. The first THP-1 cell culture was made by Dr Senta Walton, with a starting concentration of 2 x 105 cells/mL. The cell culture was then incubated at 37°C with 5% CO2 and subcultured every 2-3 days, when the cell concentration reached approximately 8 x 105 cells/mL. THP-1 cell based assay THP-1 cell based assay was performed to determine the immune modulatory effects of H. pylori and its derived products. In this assay, THP-1 cells were stimulated by 0.5 µg/mL (0.1 µg/well) Escherichia coli LPS, exposed to different H. pylori products at various product concentrations, and incubated for 22 hours.…

    Extension - temperatures of the reaction is raised to extend the primers and synthesize new strands of DNA by Taq polymerase. This is carried at a temperature of 720c (161.50F). The cycle is repeated by denaturing and synthesizing the new DNA strands with multiple copies. PCR cycle takes few hours if the cycle is automated. The thermocycler is a directed machine to program the alteration of the temperature in the reaction for denaturing and synthesizing.…

    This process of determining the specific location of a gene has become significantly better due to the advances of physical technology. In this process, which is used mainly for short genomes such as bacteria, bacterial plasmids with different restriction enzymes are cut. The orientation of these restriction sites can be determined because each restriction enzyme cuts at a specific base sequence. This technique can be used to decipher an entire base sequence of the whole strand. In agriculture, it is important to locate the bacterial plasmids when introducing bacterial DNA into plant DNA.…

    PCR is used to magnify the 16S rRNA gene and is used in molecular biology to make thousands of copies of the magnified DNA. There are three main stages that the PCR carries out, the first is denaturing when the double-stranded DNA is separated into two strands. Second, annealing which enables the DNA primers to attach to the DNA when the temperature is lowered. Lastly, extending which is when a new strand of DNA is created by the Taq polymerase enzyme when the temperature is raised. This process is run in cycles 29 times and takes approximately 4 hours to complete.…
