Unknown Organism Staphylococcus Epidermis

Micro existences share similar characteristics in their physiological makeup, and whatever counterbalance in their metabolic activity. To begin eminence a few streaks procedures are done to conclude accurate identification. In the objective world, microbiologists and medical examiners need to quickly and efficiently describe an organism to rapidly allow intervention with antibiotics. This is why a tokenish amount of experiments are done to save measure and money, and more(prenominal)(prenominal) importantly, accurately identify the microbe of interest. These tests usually begin with a differential thousand position of the organism to establish morphological characteristics. This test alone narrows down the list of possibilities by characterizing material elements such as morphological shape such as rods, cocci, spirals, chains, and so forth. The yard firebrand will reveal the gm positive (+) organisms which have a wall or plasm membrane made up pept idoglycan (a sugar + amino acid) butt the cells of the bacterium. These walls will make the crystal violet dye use initially. The hue will be darker purple dependent on how much available peptidoglycan in the plasma membrane-the more peptidoglycan-the more vivid and darker the bacteria on microscopic observations.

The plasma membrane of cells of the bacteria that do not have peptidoglycan will be thinner and made up of lipids which will not foulness with crystal violet. Instead these gram negative (-) organisms will support the pink safranin stain. After receiving my unknown culture, the first test was analyzing the color of the colony in the! culture medium Trypticase soya bean bean Agar (TSA) tube. TSA is designed with amino acids and nitrogen substances to optimise bacterial growth by providing organisms with the nutrition required to disgorge nether certain temperatures. This too is a type of differentiation since bacteria resemble variable colony colors. Then the gram stain procedure was done and observed on the microscope down the stairs fossil oil immersion on the 100x lens.
