purpose of this lab was to determine the effect of disinfectants and antiseptics on bacterial growth. By observing the effects of 5 different inhibitors including alcohol‚ bleach‚ soap solution and distilled water‚ it was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants and then a pipette was used to place bacterial culture on top. Using forceps‚ a filter disc was dipped into each inhibitor and

Research Craig S. Ricard PSY/285 Due: March 11‚ 2012 Experimental Research Recently‚ a group of teachers wanted to determine the effectiveness of using anti-bacterial gels against the spreading of germs from person to person and overall preventing them from getting the cold or flu. In order to see if using anti-bacterial gels prevents getting the flu or a cold an experiment must be performed with the teachers. The experiment must be properly performed by randomly dividing the teachers

concrete and gaining high strength of cement. We plan to make use of bacterial species which can hydrolyze the enzyme Urease efficiently to produce microbial concrete. Such bacterial are known to produce calcium which is useful in giving strength to cement. We are working in 2 stages. Stage 1: Here we check the effect of bacterial solution on cement mortar and along with that we check the effectiveness of the bacterial solution to fill the cracks in concrete by precipitation of calcium in

strikingly obscure. Sometimes the style makes his poem difficult to understand. This difficulty and obscurity arises from the extreme density and epigrammatic terseness of his style. He often writes in a telegraphic style in which connections‚ conjugations‚ articles even pronouns are often missing. Further difficulty is created by his frequent use of the terminology of modern psychology. Auden coins new words and does not hesitate to use archaic‚ obsolete and unfamiliar‚ unusual word if they suit

transcriptase translates the viral RNA into DNA‚ which is then translated again into RNA. Assembly New viruses are formed by the assembly of the different parts of the virus. After approximately 25 minutes‚ 200 new viruses are formed. Release Bacterial cell burst and the newly formed viruses are released from the host cell. Now‚ they are ready to attack new bacteria. Lysogenic Cycle. Landing The first step of lysogenic cycle is landing of the virus on the host’s cell. This is done by tail

For the completion of this experiment the procedures were guided with the Rainbow Transformation1 lab manual. An Escherichia coli bacterial reference plate was used to obtain colonies which were resuspended into a CaCl2 solution that was previously kept on an ice bath. The rainbow transformation mixture containing the plasmid DNA was then added to half of the E. coli cells. These cells were later placed into a water bath set to 42ºC and “heat shocked” to promote the entrance of DNA into the cells

Bacterial An eye with bacterial conjunctivitis Bacterial conjunctivitis causes the rapid onset of conjunctival redness‚ swelling of the eyelid‚ and mucopurulent discharge. Typically‚ symptoms develop first in one eye‚ but may spread to the other eye within 2–5 days. Bacterial conjunctivitis due to common pyogenic (pus-producing) bacteria causes marked grittiness/irritation and a stringy

------------------------------------------------- Definition Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group‚ and most commonly from carboxylic acids and alcohols. That is‚ esters are formed by condensing an acid with

Title: E. Coli Transformation with a Plasmid DNA Containing the GFP Gene Introduction: Bacterial transformation is the process of bacteria taking in and expressing exogenous DNA. This has led to many other discoveries. In order for bacterial transformation to occur the bacteria must be in a certain physical state to be able to take in DNA. This is called competency and it allows the cell membrane to be permeable so DNA can pass through. Currently researchers are studying the transformation
