considered one of the greatest newest innovations in medicine but there is still yet to be a perfect ideal antibiotic. In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

IDENTIFICATION OF AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion

Vision and the Cutaneous System. With this‚ he provided nine different categories of fingerprints‚ which we now know as arches‚ tented arches‚ loops‚ whorls‚ and twin loops. Like the previous researchers‚ he did not focus on using fingerprints for identification. In the late 1800’s‚ Sir William Herschel‚ the chief magistrate of the Hooghly district in Jungipoor‚ India‚ began imprinting fingerprints onto business contracts he made with the natives‚ since the natives were illiterate. Due to this new system

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

The identification of Bamboo using various PCR and Sequencing Techniques Abstract Often the incorrect bamboo species is sold to unsuspecting customers at shops. This can have a disastrous effect on their garden. Three separate and unknown Bamboo leaf samples were taken and were required to be distinguished genetically from one another. Using ITS-PCR DNA amplification techniques‚ the ITS region DNA was amplified and used in PCR-RFLP and RAPD PCR in order to determine the genetic identity of each

Consent Decree – Identification and Assessment One important court ruling regarding bilingual education was the case of Lau vs. Nichols‚ in early 1970. Although the court ruled children’s Fourteenth Amendment (Equal Protection) was violated‚ accountability wasn’t established. The 1990 Consent Decree addressed this issue by outlining ESOL teacher training requirements‚ as well as needs of ESOL students needing to be addressed by school districts. Before the Florida Consent Decree‚ there
