Home come E.coli can't grow on Simmons Citrate Media?
E.coli is unable to grow on Simmons Citrate Media because it lacks the ability to utilize citrate as a carbon source. This is due to the absence of the citrate permease enzyme needed to transport citrate into the cell for metabolism. As a result, E.coli is unable to grow on this type of media.
Why pH of Simmon's citrate agar increase if citrate is utilized?
This is due to the production of oxalacetic acid and acetate, when the enzyme citrase acts on the citrate. the oxalacetic acid and acetate is enzymatically converted to pyruvic acid and carbon dioxide. the carbon dioxide combines with sodium and water forming sodium carbonate which in turns makes the medium alkaline.
Does Gene Simmons drink alcohol?
Gene Simmons has been open about his decision not to drink alcohol. He has stated that he chooses not to consume alcohol due to personal preference and health reasons.
What is a body tissue?
A body tissue is a group of cells that work together to perform a similar function. Examples of body tissues include epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Tissues combine to form organs and organ systems in the body.
Is it possible to lick your elbow?
Elbow LickingThis is from Guinness World Records: "Elbow Licking. Contrary to popular urban legend, it is quite possible to lick your own elbow. Guinness World Records receives about five claims a day for this and stresses the following point: Being able to lick your own elbow is not, in any sense, a world record. If you're one of the rare few who can lick your elbow, save it for the water cooler." It is possible to lick your own elbow. There is an urban legend that says that it is impossible to kiss your own elbow and if you do, it says you will turn into the opposite sex. Of course this is not true.
If an organism is able to convert the sodium citrate in simmons citrate agar to pyruvate what are some possible reasons why an organism might ferment rather than metabolize it oxidatively in the Krebs?
Citrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to pyruvate and CO2.
What is the result of citrate test for bacillus licheniformis?
The result is the initial green color of the Simmons Citrate Agar turning blue; generating a positive indication that the organism does indeed utilize citrate as the sole source of carbon and energy.

What gram negative facultative anaerobic bacteria are lipase negative and Simmons citrate negative?
E. Coli
WHY IS NITROGEN SUPPLIED AS AMMONIUM SALTS (SPECIFICALLY) RATHER THAN AS AMINO ACIDS IN SIMMONS CITRATE AGAR?
If amino acids were used they would not produce the same degree of pH change that results in color change of the indicator.
What is simmons citrate agar?
Simmons citrate agar is a differential agar used to determine if a sample bacteria can utilize citrate as its only carbon source. The agar is initially a green color due to the bromo thymol blue pH indicator in it. If a bacteria uses the citrate, the by-products are ammonia and ammonium hydroxide both of which will alkalize the agar and increase the pH to the point of changing the indicator's color to blue, so the whole agar turns from green to blue.

What reagents do you add for each of the imvic test?
For the Indole test, you add Kovac's reagent. For the Methyl Red test, you add Methyl Red indicator. For the Voges-Proskauer test, you add alpha-naphthol and potassium hydroxide. And for the Citrate test, you add Simmons citrate agar.
