Introduction: Microorganisms are everywhere, and they are usually associated with sickness or disease like E. Coli or Staphylococci. In reality, microorganisms help more than they harm. Microorganisms in our bodies help make everyday normal bodily functions possible. For example, normal microbiota found on the skin and gastrointestinal microbiota found in the digestive tract. If it was not present, it would make humans a lot more susceptible to harmful microorganisms. Without microorganisms, any disease would most likely happen more often and to more people. To learn more about microorganisms, in lab environmental samples were obtained. Throughout the semester characteristics of the …show more content…
This technique allows for isolated colonies. Obtaining isolated colonies is the first step in determining the microorganisms characteristics. The isolated colonies of the environmental isolate appeared white and were medium in size. In laboratory three, 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 laboratory four through simple staining. Single staining consists of a single dye which informs only about cell shape and size, rather than differences between cell components. Through the simple stain, it was found that the unknown is a staphylococcus microorganism which is spherical and in clusters. The gram stain was performed in laboratory six and this helped determine whether the
