Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling

The crystal violet was on the slide for 1 minute rather than 20 seconds. The decolorizing step was used with alcohol for 10 seconds rather than 20 seconds. The only other change was that the safranin was on the slide for 1 minute instead of the recommended 20 seconds. The slide was put under the microscope at 1000x
