INTRODUCTION: In this laboratory exercise explore the differences of microorganism and continue our use of specialized media and use some biochemical testing.This report discloses the basic laboratory instruments will be used in each of our practices .It is of great importance to recognize and identify the different instruments and laboratory tools‚ because in this way will we be able to use them properly and also to call them by name and know why.

1. Appears as grape-like clusters when viewed through a microscope‚ and has large‚ round‚ golden-yellow colonies‚ often with hemolysis‚ when grown on blood agar plates. 2. Microorganisms that are used to assess the microbial quality of swimming pool and similar environments include heterotrophic plate count – HPC (a general measure of non-specific microbial levels)‚ faecal indicators (such as thermotolerant coliforms‚ E. coli)‚ Pseudomonas aeruginosa‚ Staphylococcus aureus and Legionella spp. HPC

definitely want to know that the compound is effective against the organism(s) you are trying to eliminate. This project shows you one method of measuring the effectiveness of an antimicrobial agent against bacteria grown in culture. This is called the Kirby-Bauer disk-diffusion method‚ and here is how it works. The bacteria of interest are swabbed uniformly across a culture plate. Then a filter-paper disk‚ impregnated with the compound to be tested‚ is placed on the surface of the agar. The compound diffuses

smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth‚ although some live in slightly hypotonic solutions. (Alonzo‚ 2008) Growth in NaCl Solutions Samples of S. cerevisiae and S. epidermidis were placed into sodium chloride (NaCl) solutions of 1‚ 7 and 15 percent which were supplied in the lab kit. The S. cerevisiae results are as follows. After 24 hours of observation there was a moderate amount of growth in the 1% NaCl solution

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:

Base Stains (+ Charge)- Stains Cell- Methylene Blue‚ Crystal Violet‚ Safranin Differential Staining Techniques- Any Staining Technique using 2 or more stains is differential. It allows us to differentiate between parts. 1. Gram Stain- Two Stains‚ PLUS Reagents- Distinguishes Chemical Composition of Cell Wall PG only (+ Purple)

Some organisms were too large to measure. Antibiotics were susceptible to bacteria and had less growth‚ whereas antiseptics were resistant to bacteria‚ and had more growth. Antiseptic of S. epidermidis had more growth than antibiotic of S. epidermidis. Antiseptics of S. epidermidis were most effective and Mr. clean had more growth all over the agar. S. epidermis of antibiotic were the most effective because it was susceptible and Chloramphenicol and tetracycline had a little bit of

The Effect of Acetyltransferases on 2 different strains of E. coli Introduction Scientists have recently discovered that resistance to antibiotics may not be such a new thing. Evidence of bacteria samples in Canadian permafrost proposes that these resistances have been around for at least 30‚000 years (Luiggi 2011). In our required pre-lab reading‚ we learned tuberculosis is becoming increasingly drug-resistant‚ giving proof that bacteria can adapt to necessary changes in order to survive (Barry
