turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you used the E. coli or B. megaterium and number the quadrants 1 through 4. Please keep in mind that one pair will test the E. coli and Environment 1 or 2‚ and one pair will test B. megaterium and Environment 1 or 2. After‚ you will need to swab the E. coli and B. megaterium on two different nutrient agar plates using a sterile disposable inoculating loop. Remember not to dig in into the agar or the

source. Simmon’s citrate agar will be prepared by using Oxoid well-prepared Simmon’s citrate agar powder. The Simmon’s citrate agar was prepared by using Oxoid well-prepared Simmon’s citrate agar powder. The preparation was began by suspending 5.75g of the powder in 250 ml of distilled water and mixed thoroughly. The following shows the amount of each composition in 1 litre of Simmon’s citrate agar solution prepared using Simmon’s citrate agar powder. This Simmon’s citrate agar solution was then heated

Title: What is the effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement

INTRODUCTION Background Totipotency is the ability of a single cell to divide and produce all the differentiated cells in an organism‚ including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes

Data has been presented in the tables‚ charts and drawings herein and reflect the results of microscopic observations as well as the differential tests results on various agars and broth cultures. Although all tests were not conclusive‚ the unknown organism labeled Unknown #11 was found to be a member of the family Enterobacteriacea and Genus Serratia marcescens.

analysis. Most frequently‚ the identification of a specific organism must be accompanied by a sensitivity study. Also due to the changing patterns of resistance in other bacteria to antibacterial agents‚ sensitivity studies are essential. Clinically‚ the agar diffusion method is commonly used. The organism can be reported as being sensitive‚ intermediate or resistant to an antibiotic. Sensitivity depends on the growth characteristics of the organism and diffusion characteristics of the antibiotic. Some

a given sample. It enumerates the number of actual live‚ viable cells in the sample that form colonies on a suitable agar medium. As the optimum medium and conditions varies for one sample to another‚ the colony count methods provide an estimate of the number of viable cells according to the medium employed‚ time and temperature of incubation. Each colony that appears on the agar plate arising either from a clump of cells or from a single cell is referred as a colony forming unit (CFU). The sample
