Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The

microorganisms with the naked eye‚ they are present in virtually every habitat known 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

Observation of Bacteria on Chicken and Handrail and the Effect of GermX® and Alcohol on Them. Sujit Bhimireddy‚ Daryl Onwuchuruba‚ Naveen Sood‚ and Manasa Tripuraneni Biology 106 Abstract Bacteria are found everywhere on this planet. This experiment is aimed at observing some of the bacteria that surround us in places that we use everyday. We will look at bacteria found on a piece of chicken and bacteria found on a handrail. The effectiveness of antibacterial substances such as GermX® and

In the case of gram-positive bacteria‚ the cell wall is comprised of 60-90% peptidoglycan and is very thick. There are numerous layers of teichoic acid bound with peptidoglycan
