The unknown soda ash from experiment 3 was used‚ to determine the weight for each trial we used the equation of (M of HCl) x (18 ml x 105.99) / (10 x 2 x Na2CO3 ). Which was equal to (0.01472 M) x ((18 mL X 105.99)(10 x 2 X 2.428 % )= 0.6 g. To start we had to rinse the beakers‚ electrode and the stirring bar with diluted water. The sample we needed was weighted to the closest 0.1 mg which we got was 0.3 for the first trial. The sample was transferred to a 250 mL beaker and dissolved in 70 mL of

Determining the Unknown Microorganism from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by

as are their abilities to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant because they are not only beneficial but potentially hazardous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding

MICROBIOLOGY 3444-007 Gram Negative Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to

Determining pH Using a Red Cabbage Farnoosh Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator

Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in

The pathogen that causes Staphylococcus is called Staphylococcus aureus. Staphylococcus aureus is also called Staph and is abbreviated to S. aureus or Staph aureus in medical literature. S. aureus is a bacterium that causes various infections. Staph is a commonly found on the skin and also in mucus membranes (mostly the nose and throat) of up to 25% of healthy people and animals. Depending on the type of strain S. aureus‚ can cause minor skin infections such as pimples‚ boils‚ carbuncles‚ and

organism used for this experiment was Saccharomyces cerevisiae (S. cerevisiae) which is often called baker’s yeast. S. cerevisiae has several characteristics that make it an ideal organism to use in experiments. S. cerevisiae is a single-celled eukaryote capable of reproducing through mitosis or sporulation. This means that the yeast has both a haploid and a diploid stage. In yeast‚ the haploid cells are n=16 and the diploid cells are 2n=32. S. cerevisiae has two haploid mating types MATɑ and MATa. When
