Lab Report Essay

The metabolic activities of microorganism are frequently used to identify bacteria species. There are four useful reactions that are commonly used to examine several metabolic activities of microorganism which are carbohydrate fermentation test, Voges-Proskauer test, Methyl Red test and Citrate utilization test. The first test involved in this this experiment is the carbohydrate fermentation test. Fermentation is a metabolic process that performed by almost all types of bacteria. Adenosine triphosphate

writing is lab reports. Lab reports are a form of writing that provides formal record of research or an experiment. These reports consist of objectives, procedures, and results that should be specific enough that interested readers could replicate the experiment. When doing research on lab reports I learned about how a lab report is its own

4.2 Materials and Method 4.2.1 Materials The size of the particle should be large enough to allow three proteins coupling together onto one particle. Therefore, Dynal® MyOneTM 1-μm carboxyl particle (Invitrogen®) and Merck® EM1-100/40 particle were used as the carrier particles. If positive results were seen, the work would be expanded to particles in other sizes, materials and manufacturers, such as Allrun® PM3-050 or Dynal® M270 particles. The proteins chosen for coupling were mouse IgG, streptavidin

Observations of imploding thin-shell capsules have demonstrated an increasing discrepancy between predictions from single fluid hydrodynamic simulations and experimentally measured fusion yield as the Knudsen number (mean-free-path over system size) is increased. (-- removed HTML --) (-- removed HTML --) 1,2 (-- removed HTML --) (-- removed HTML --) The sensitive dependence on the Knudsen number indicates that these discrepancies may be due to a breakdown of single fluid hydrodynamics and thus

Material and methods Cell lines and culture conditions SKBR3 (breast adenocarcinoma) and BT-474 (breast ductal carcinoma) cells, which are HER2 positive models, were purchased from DMSZ (Braunschweig, Germany). SKBR3 cell line was grown in Dulbecco’s Modified Eagle Medium (DMEM; Gibco/ Invitrogen, Carsbad, CA, USA) and supplemented with 15% fetal bovine serum (F.B.S; Gibco/Invitrogen), 10mg/ml insulin (Sigma Aldrich, USA) and penicillin-streptomycin (100 x solutions, Invitrogen). Moreover, BT-474

laboratory class by applying the microorganism to the tests that have been performed in the class prior to the identification of the unknown. First, the lab professor handed out a bacteria that was on the unknown streak plate labeled B5 that consisted of an unknown gram positive or gram negative bacteria. A sterile technique was performed by the lab manual instructions which is stated in the references.

Science and Forestry. Soil samples were gathered from both primary and secondary forest at Skaneateles Conservation Area, Onondaga County, New York. Soil samples from the primary and the secondary were used to determine the water content. In this lab, we used sterile technique to avoid any contamination of sterile media and equipment during cell culture of unwanted microbes. This technique involves using flames to kill contaminating organisms and a to minimize the exposure of sterile media and equipment

phenylethyl alcohol to change the membrane permeability of Gram-negative bacteria (13). Growth on the plate indicated a positive result. Lack of growth on the EMB plate also suggested a Gram-positive bacterium. This was because the medium contained a methylene blue dye that hindered the growth of such bacteria (14). The high sodium content of the MSA plate created a high osmotic pressure that inhibited the growth of species that cannot withstand the pressure (15). Thus, observed growth indicated

5 / 10 To prep our purified PCR product and our PCR control for electrophoresis, we added 4 microliters of Blue Juice loading buffer to each sample. The samples were then loaded into the wells of the gel along with a DNA Size Standard. The electrophoresis chamber was then turned on and the voltage setting was switched to high. The electrical current applied to the chamber caused negatively charged DNA molecules to move from the positive end to the negative end, with the smallest fragments moving
