For the culture media tests, synthetic medium, tryptic soy broth (TSB), SF medium, MacConkey agar, and nutrient agar and glucose were used to detect if specific organisms would grow on each media. Synthetic medium is defined media and the contents are exactly known. A positive result would be if one could see cells within the medium after incubation, and means that the the media provides all the nutrients the organism needs to grow. A negative result would be a clear medium without physical signs of growth, and means that the organism requires supplementation. TSB is a complex medium in which the exact chemical composition is unknown. A positive result is positive growth of cells within it, and it shows that the bacteria inoculated within it is aerobic and growth is supported. A negative result is lack of growth and it indicates that the bacteria inoculated within it is not aerobic. The test works by being selective and only allowing the growth of aerobic bacteria. SF broth is a selective medium and is used to select certain organisms by providing the correct environment and nutrients needed to grow. A positive result will elicit a color change of the media from purple to yellow. A negative
