active dried yeasts (ADY). This experiment allowed the students to perform the plate count technique by serial dilution and two common methods‚ spread plate and pour plate to determine the colony forming unit (CFU) of yeasts A ten-fold dilution is used in this experiment‚ the sample is diluted until it reached the 10-9 dilution. Plating for spread plate started from 10-5‚ 10-6‚ 10-7 and 10-8 dilution while for pour plate‚ it started from 10-6‚ 10-7‚ 10-8 and 10-9 dilution. Having incubated inverted

used to test antimicrobial activity against disease causing bacteria Staphylococcuaureus. Extracts of varying concentrations of Azadirachtaindica fruit pulp and leaf extract were prepared using Phosphate Buffer and tested against test organisms using agar diffusion method. Oxfloxacinof same varying concentrations were used to compare the effect of antimicrobial activity of fruit pulp and leaf extract. Keywords: Azadirachtaindica‚ Antimicrobial activity‚ Staphylococcus aureus. I. INTRODUCTION Azadirachtaindica

organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques of microbiology are used in the following five experiments. The first experiment used Trypticase Soy Nutrient Agar (TSA)‚ which can grow a wide variety of organisms

Prior to use‚ melt and hold at 50c in a water bath 5 tubes of 9.0 ml trypticase soy (TS) broth 1 ml sterile pipettes Pipette aids Methods: 1. We began the experiment by marking the plates and place them in order from 10^5‚ 10^6‚ 10^7‚ then have the blank dilutions ready in order from 10^-4

Background Information: Pinesol and Lysol are both common household disinfectants that make very big commercial claims; both claim to kill 99.9 percent of bacteria. Lysol contains

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 out from the filter paper into the agar. The concentration of the compound will be higher next to the disk‚ and will decrease gradually as distance from the disk increases. If the compound is effective against bacteria at a certain concentration‚ no colonies will grow wherever the concentration in the agar is greater than or equal to

unknown mixture‚ using a number of laboratory tests. Over the semester‚ multiple tests were carried out to identify between gram-positive and gram-negative bacteria including the Mannitol Salt Agar (MSA) media test‚ which selects only for gram positive bacteria‚ and the use of Eosin Methylene Blue Levine (EMB) Agar media‚ which selects for gram negative bacteria and differentiates between lactose fermenters (paracolons) and non-lactose fermenters (coliforms).These tests along with other selective and/or

yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method and most probable number method. The viable count is very specidic‚ as it represents the number of colony forming
