The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

Gram Negative Unknown Lab Report Abstract The Unknown Gram Negative bacterium inoculated in a Tryptic Soy broth medium was randomly selected from a group of other unknowns. In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P

Purpose: The purpose of this experiment was to be able to apply our knowledge of chemistry to identify 10 unknown elements that were presented to us. We were allowed to use Bunsen burners‚ hydrochloric acid‚ use PH paper to test if the unknown solution is an acid or a base‚ and precipitate each unknown solution with each other. Procedure / Data / Conclusions: Unknown #1: I found solution 1 to be KI. While doing the precipitate reactions‚ I found that it precipitates only

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

Identification and Diagnosis of Unknown Enteric Bacteria in an Infected Patient Using an Enteropluritube Brooke Addario 2/16/2015 BIO 488C - Section J TA – Jacob Karsten Introduction: Enteric bacteria are members of the Enterobacteriaceae family of microorganisms. These gram negative‚ rod shaped‚ facultative anaerobes are found in the intestinal tracts of humans and animals. Enteric bacteria can be pathogenic; however‚ they are also a normal part of human bacterial flora and are therefore
