None Turned Yellow Positive maltose fermenter Lactose Fermentation To determine if the microbe can ferment the carbohydrate sugar lactose as a carbon source. Microbiology Unknown 1 was found in a nearby pond that was created by an earthquake.
They can also be present in the urinary tract and most commonly causes Urinary Tract Infections. This is done to know the morphology of the microbe.
The nine tests performed on the microbe were done according to the index of the virtual unknown software and the results of each test correlated to the results anticipated. None Turned pink Negative adonitol test Cellobiose Fermentation To determine if The unknown essay microbe can ferment the carbohydrate sugar cellobiose as a carbon source.
It has the ability to recycle hydrogen. None Turned Yellow Positive cellobiose fermenter Maltose Fermentation To determine if the microbe can ferment the carbohydrate sugar maltose as a carbon source. Table 1 shows the tests, purpose, reagents and results of the various tests performed.
As a result, it was concluded that the unknown 1 microbe was Citrobacter amalonaticus. First the shape and color of the microbe was noted. Once the morphology of the microbe was identified, it was isolated and inoculated into a test tube. Some of the various methods introduced and practiced in class were applied in identifying the microbe.
Citrobacter amalonaticus has a gram negative rod-shape. Citrobacter amalonaticus is also known as an opportunist pathogen. In addition it is capable of breaking down nitrates into nitrites in the nitrogen cycle. The reagent does not mix with water and forms a thin layer above the broth. Besides being found in the intestines of humans, Citrobacter amalonaticus is usually found in the ground soilin the air and in the intestines of animals such as bats.
Opportunist pathogens are pathogens that do not cause much damage to healthy individuals; however, it can cause very severe damage to those with a weakened immune system. None Turned Pink Negative melibiose fermenter Indole Production To determine whether the microbe can produce indole from the amino acid tryptophan.
This process is commonly used in the biodegration industry. Procedures were followed as stated in the index of the Virtual Unknown Software. Each test was performed according to the index of the Virtual Unknown software and the following tests were performed: The reagent reacts with idole to produce a cherry red ring.
After concluding that the microbe was Gram negative rods, it was inoculated into a previously prepared test tube. They can be found in the digestive system and are linked with digestive disorders such as diarrhea. This allows for the harmful substances such as uranium to be removed from water, soil and uranyl phosphate crystals.
None Turned yellow Positive sorbitol fermentation Sucrose Fermentation To determine if the microbe can ferment the carbohydrate sucrose as a carbon source None Turned Pink Negative sucrose fermenter Melibiose Fermentation To determine if the microbe can ferment the carbohydrate sugar melibiose as a carbon.
None Turned pink Negative raffinose fermenter Sorbitol Fermentation To determine if the microbe can ferment the carbohydrate sorbitol as a carbon source.
None Turned Pink Negative lactose fermenter Raffinose Fermentation To determine whether the microbe can use sugar raffinose for carbon and energy.
