bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and to subsequently utilize those techniques for

(Iodine) are an appropriate antiseptic to can kill a sample bacterial contaminant found in the local environment‚ and if so‚ which is the most effective? The purpose of this experiment is to determine the antibacterial effectiveness of Scope‚ Listerine‚ Bactine‚ and Iodine in relation to each other. Scope‚ Listerine‚ Bactine‚ and Iodine each are believed to be effective antiseptics: * Scope Mouthwash - Kills 99% of bad breath germs (in lab tests) http://www.scopemouthwash.com/scope-products/scope-mouthwash-original-mint

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more

Transformation of E. coli with your unknown plasmid Learning Goals: Insert your uncut unknown plasmid into chemically competent DH-5 E.coli cells and use antibiotic resistance to confirm the success of the transformation. You should familiarize yourself with the various methods of transformation and the advantages/disadvantages of each type. You should also understand how heat shock transformation works and how chemically competent cells make this type of transformation possible. For this transformation

Bacterial Vaginosis is a bacterial infection. This STD occurs when there is an overgrowth of bacteria that is normally present in the vagina. BV can only be spread through female sexual interactions. Males are not able to get this STD because they do not have the same bacteria as women. There are rarely ever any extremely noticeable symptoms. Some symptoms of bacterial vaginosis include; abnormal vaginal discharge‚ vaginal itching‚ odor‚ and/or burning when urinating. Since the symptoms can be unnoticeable

Transformations in Ovid Transformations from one shape or form into another are the central theme in Ovid’s Metamorphoses. The popularity and timelessness of this work stems from the manner of story telling. Ovid takes stories relevant to his culture and time period‚ and weaves them together into one work with a connecting theme of transformation throughout. The thread of humor that runs through Metamorphoses is consistent with the satire and commentary of the work. The theme is presented

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

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

Since then the mortality rate from bacterial meningitis has not changed much despite the introduction of new antibiotics and treatments (Hussein 360). In the case of bacterial meningitis no one casual organism causes all of the cases‚ but rather there are many that capable of causing it. Although there are many causal organisms‚ there are three that are
