Cell Biology- Osmosis‚ Cell Size and Diffusion and Enzymes 1.0 INTRODUCTION Cells are the basic building blocks of all living things. They provide structure for the body‚ take in nutrients from the food‚ convert those nutrients into energy‚ and carry out specialized functions. Cells also contain the body’s genetic material and can make copies of themselves. A cell is also a metabolic compartment where many different chemical reaction occur. There are two types of cells‚ eukaryotic and prokaryotic

test‚ such as the Kirby Bauer Method‚ are used to determine susceptibility to various antimicrobials. Why are they not used to determine resistance? a. They grow a resistance to antibiotics and antimicrobials. Kirby Bauer is used to determine diffusion of a disk‚ to measure the effectiveness of antibiotics towards pathogenic microbes. 4. Compare and contrast the following terms: antiseptic‚ disinfectant‚ sterilant. Provide one example for each of the terms. a. Antiseptic is used on living

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows the agents to diffuse freely‚ and a growth medium is incubated over its’ surface. During incubation‚ the chemotherapeutic agents move from levels of high concentration‚ to low levels

Objectives 1. To determine biochemical activities of microorganisms. 2. To observe the product of biochemical activities of microorganisms. 3. To learn the skills of inoculation agar tubes and agar plates. Introduction Microorganisms are able to carry out different biochemical activities with the ease of different enzymes. Each of these enzymes carries out one specific type of the chemical transformation. They convert substrates into product. A) Carbohydrates Fermentation Microorganisms utilize

Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this experiment. The first (Nutrient) allowed for growth of both E. coli and S. aureus. The second agar used (MKL) inhibited the growth of S. aureus but allowed the growth of E. coli
