    in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible. Once stained‚ cell morphology can be observed. Stains are solutions that contain a solute called a chromophore dissolved in a solvent. A chromophore is the color possessing

    INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial species from

    to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory exercise you will examine the ubiquity and diversity of various microbes that are present in the environment or inhabit the human body. Most bacteria that

    Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X
