This was compleated by growing the bacteria on a petri dish with agar‚ gram staining‚ then examning under a microscope. The bacteria identified was M. Roseus and B. Megaterium. The identity of these bacteria was mostly determined by the positve gram stain results and the shape they where under the microscope. Both of these bacteria

be either organic‚ meaning from a living organism‚ or inorganic‚ such as carbon dioxide. Prokaryotes split into two lineages known as Archae and Bacteria. The Bacteria are more numerous than the Archae. Bacteria can be endospore-forming bacteria. Bacteria that form endospores are able to survive harsh and severe conditions. Bacteria can also be Enteric Bacteria‚ they inhabit the intestinal tracts of animals. One species is

The results will be recorded. Key words: soil‚ microbes‚ microbial activity‚ antimicrobial

Aseptic Technique and Culturing Microbes‚ Lab #3 Purpose: The purpose of the this experiment is to learn to transfer microorganisms to a nutrient medium to promote growth using aseptic techniques. which are a method used to prevent unwanted organisms from contaminating a medium. We will also learn about different types of culture media‚ including MRS broth and nutrient broth‚ learn about oxygen and temperature requirements for microbial growth and how to control microbial growth. Procedure:

Notes for WK2 – 10 September Lesson 1 * State the resolution and magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object

ABSTRACT The exercise was about the techniques in proper sectioning of plant tissues and staining techniques so that the study of plant structure will be easier. In free hand sectioning‚ the plant organ must be 45° upright and is held between the thumb and the base of the forefinger. A razor blade was used to cut the plant thinly in cross sections. Obliquely cut tissue is a big mistake since the surface of the tissue will not be even upon viewing under the microscope. Iodine-Potassium-Iodide

Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

surface stains‚ where the staining substance is spilled out onto the surface or material and is trapped in the fibers‚ pores‚ indentations or other capillary structure of that surface. The material that is trapped coats the underlying material‚ and the stain reflects back light according to it’s own color. Applying paint‚ spilled food‚ and wood stains are of this nature. A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types
