Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils.

These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to

GRAM STAIN THEORY: The most widely used staining procedure in microbiology is the Gram stain‚ discovered by the Danish scientist and physician Hans Christian Joachim Gram in 1884. Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives. The procedure is based on the ability of microorganisms to retain color of the stains used during the gram

Gram Staining of Bacteria Since bacteria is really small microbiologist use stains to help them see bacteria more clearly under the microscope. Many of the stains they use color the bacteria cells directly and are called direct stains. Bacteria cells have a slightly negative charge while direct stains have a slightly positive charge that helps the stain bin to the bacteria. The strength of the binding from the stains depends on the make-up of the cell wall itself. Gram staining is the most helpful
