If bacterium cannot use glucose the fermentation tube will stay the same color. Gas may also occur inside the fermentation tube.
Bacterial growth will be inhibited.
Positive
this test is used to identify bacteria which use citrate as sole source of carbon e.g klebsila, pseudomonas aerogenosa
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.
it tests the ability of a bacteria to use citrate as its sole carbon source. if its positive, it will raise the pH and there will be no acid in the end product.
No, Catalase +ve, Coagulase +ve, Gram + cocci. Citrate test is usually used to differentiate members of the Family Enterobacteriaceae. Check Bergeys systematic bacteriology. 1980
Citrate Permease is an enzyme that is responsible for transporting citrate inside the cell. Some bacteria have this enzyme while others do not. You can test for the presence of citrate permease by performing a Simmon's Citrate biochemical test.

The Eosine Methylene Blue test is selective for only gram-negative bacteria. It is possible for gram-positive bacteria to grow, but it would barely grow. Staphylococcus are gram-positive spherical bacteria. So it would not grow on the Eosine methylene Blue Agar.
Any type of liquid, even water, will do fine. Although agar is best recommended as it has a lot of nutrients, allowing lots of bacteria to grow. Other liquids work but they don't grow as much and as vigorously.
Staphylococcus Epidermidis does return a gram positive result on the citrate lab test. Gram stains will produce these results on slides.
The test indicates if an organism utilizes Citrate as it's only source of Carbon. Positive results will show growth on slant as well as changing the medium from green to blue (ph indicator)
An agar slant is when a test tube is filled with liquid agar and allowed to cool and harden at an angle (slant). Agar is mixed with other nutrients to provide a medium for which bacteria can grow on.
Staphylococcus epidermidis indole test - negative methyl red - negative voges proskauer test - positive citrate test - no idea
No, Catalase +ve, Coagulase +ve, Gram + cocci. Citrate test is usually used to differentiate members of the Family Enterobacteriaceae. Check Bergeys systematic bacteriology. 1980
