Unknown Organism Report Unknown Organism # 4 Klebsiella pneumonia Klebsiella pneumonia has a rod gram stain with the agar slant cultural characteristics being slimy‚ white‚ somewhat translucent‚ raised growth. It is small gram-negative coccobacilli that can cause lobar pneumonia. The litmus milk reaction is acid‚ gas‚ and curd with a variable reaction. Klebsiella can grow either in the presence or absence of oxygen because of its nature of being a facultative anaerobe. Oxygen is a preferred energy

The book‚ “Adventures in the Unknown Interior of America” was translated and edited by Cyclone Covey in 1961. It is a semiofficial report (more like a personal diary) written by Alvar Nuñez Cabeza de Vaca to the King of Spain regarding the Narváez expedition. The original report by Cabeza de Vaca was titled‚ La Relación (1542) along with supplemental material called the Joint Report was used to describe the epic events that happened on the expedition. Cabeza de Vaca was born in 1490 in the town

LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt‚ x. The salt is crystalline‚ deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt x with NaOH‚ or NH4OH the cation could be distinguished by observing the color changes or solubility while reacting salt x with H2SO4 or a mixture of copper

How the unknown heroes of the Civil Rights Movement helped organize the March on Washington December 1962: « Things aren’t moving fast enough‚ Martin. »‚ [Bayard] Rustin sighed‚ stubbing out his cigarette in the ashtray. Martin [Luther King Jr] could almost hear the disappointment in his voice. Rustin would never say it explicitly – he was too respectful and tactful - but Martin could sense it. They have known each other for six years now. Rustin helped organize the Montgomery Bus Boycott that

The aim of this experiment was to calculate the concentration of an unknown solution of Sodium Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the

of biological system is usually preferred as the pH system‚ which determines the pH level of dilute aqueous solutions. In this laboratory‚ the data collected from the experiment will be used to graph the titration curves which help to identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell. Since

Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance equal to

Determining an Unknown Through Deferential Stains and Biochemical Tests Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification
