Various test performed to identify two bacterium that were unknown, one was plaque that were scrapped from the teeth and the second was an unknown given. It resulted that the unknown bacterium is Staphylococcus epidermidis. Staphylococcus epidermidis has three drug resistance, and no secondary metabolites. The plaque scrapped from the teeth had a morphology of bacilli and is gram positive. Staphylococcus is gram positive, it is catalase positive and oxidase negative. The minimal inhibition concentration
cream,yoghurt and probiotic yoghurt products can be a rich source of diverse lactic acid bacteria.The objective of this lab practical was to isolate lactic acid bacteria(LAB) form raw milk,establishment of pure cultures of LAB,identify LAB and phage recovery and enumeration of recoverd phage.Raw milk was chosen as a sample so as to have a more positive result.To identify bacteria Lab isolated from raw milk,biochemical,morphological ,physiological and cultural characteristics were employed. The purification
when one gains even a very basic knowledge of how diseases are acquired and spread. The purpose of this lab was to collect and observe microbes from environmental and human body samples by culturing them on the appropriate media using aseptic transfer techniques.
UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others
Lab12-Medical Microbiology- Part1– Differential Media/Biochemical Tests, Sp2012 (Set all of your margins to ½”) Purpose: The purpose of this lab is to help you become a little familiar with some of the tests that can be typically performed in a clinical or research lab facility. These tests may help in determining a particular pathogen’s growth needs. There are several sections to this lab. Find each section and complete the “Preparing for Class” sections.

Lab Report A differential staining procedure used in microbiology is called the Gram stain. The significance of the Gram staining procedure is that it differentiates the bacteria into two groups. The Gram reaction of a bacterium adds valuable information for the treatment of disease. The Endospore stain is a special stain that is used to determine the presence of endospores in bacteria. This stain is used to detect if certain bacterium cell contain highly opposing spores within their vegetative
Introduction: The study conducted was to determine the unknown bacterium that was given by the Microbiology lab instructor. The purpose of this exercise is to go through a series of testing in order to identify a microorganism, how it grows, reproduces and how the bacteria can be treated and killed. The techniques involved in this study included; what type of agar to use, inoculating, proper sterilization, gram staining and how to handle bacteria in order to avoid contamination. Materials and Methods:
Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x, 40x, and 100x (oil immersion) objective lenses, which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge
HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased, not the writing. The purpose of scientific writing is not to entertain, but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports.
