I think that there are two possible answers....first, Nocardia and, also, Bacillus anthracis. Lactobacillus might also work; however it is a microaerophilic organism and can only tolerate lesser levels of oxygen than a true aerobic organism. But all three are gram positive and, I believe, thrive with both dextrose and citrate.
Nocardia has a Trycarboxylic acid cycle which utilizes both dextrose and citrate.
The answer is: Ps. aeruginosa
Most bacteria in Tribe V are able to utilize Citrate, with the exception of Hafnia and Pantoea (+/-). The 2 most common Klebsiella (oxytoca and pneumoniae), can utilize citrate, so should be citrate positive.
The positive test control organism for citrate utilization test is Klebsiella pneumoniae
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.
citrate result is positive in case of pseudomonas aeroginosa. slant and butt both will be positive
Staphylococcus Epidermidis does return a gram positive result on the citrate lab test. Gram stains will produce these results on slides.
Bacillus megaterium
Citrate phosphate dextrose is an anticoagulant used to preserve blood and blood products.
how can i prepare ferric ammonium citrate redish crystals
Most bacteria in Tribe V are able to utilize Citrate, with the exception of Hafnia and Pantoea (+/-). The 2 most common Klebsiella (oxytoca and pneumoniae), can utilize citrate, so should be citrate positive.
citrate phosphate dextrose adenine
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.
bacillus subtilis
S.maltophila
This Bacillus is the source of BamH 1 restitution enzyme, and as the name indicates it freaks down starch, but I know nothing of citrate utilization by this bacteria.
The most common anticoagulants for phlebotomy aas found in your evacuated tubes are: Sodium Citrate Sodium or Lithium Heparin EDTA (Ethylene Diamine Tetraacetic Acid) Potassium Oxalate Sodium Phosphate Sulfonamide (SPS) Citrate Phosphate Dextrose (CPD) Acid Citrate Dextrose (ACD)
The B.cereus has a positive citrate test and a negative Voges Proskauer.
M. Morganii is citrate negative
