followed. First‚ disinfection of the isolation room where tests are performed would be done for every use. 70% ethanol is used to kill unwanted microorganisms. This concentration of the ethyl alcohol is believed to be the most effective to kill bacteria since higher concentrations of ethyl alcohol deprives the bacterial cell of water which prevents the alcohol itself to destroy the bacterial cell wall‚ thus inhibit their death (Lorian‚ 2005). It will be applied to surfaces of the laboratory‚ tables

science project to be researched and experimented is whether bacteria can become resistant to antibacterial soaps. Bacteria will be grown in an agar broth containing .01%‚ .1%‚ .5% and 10% antibacterial soap. To fully understand the subject‚ information on everything necessary to conduct this experiment and comprehend the results was researched. Once the experiment is completed a conclusion will be able to be made as to whether or not bacteria can become resistant to antibacterial soaps The procedure

were measured and recorded. A hypothesis that was formulated before experimenting was‚ “If the type of disinfectant is Mouthwash‚ then it will allow for the least amount of bacteria growth because the chemicals present in Mouthwash combined with the acidic environment it bring will make it very hard to allow for any bacteria growth”. The independent variable in this experiment was undeniably

Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the

Unknown #11: Citrobacter freundii Tryptic Soy Agar Test (TSA): TSA is a basic medium that is most similar to nutrient agar. The agar contains carbon‚ nitrogen‚ sodium chloride‚ and agar. This allows for the growth of a large variety of microorganisms to grow and ferment in the medium. Mannitol Salt Agar (MSA): MSA is a selective and differential medium that favors the growth of salt loving organisms. It is commonly used to distinguish the different species of Staphylococci.

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental
