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.
What else can I help you with?
Is staphylococcus epidermidis citrate positive?
No, Staphylococcus epidermidis is typically citrate negative, meaning it cannot utilize citrate as a carbon source for growth. This characteristic can be used in biochemical tests to help differentiate it from other bacteria.
Is bacillus cereus positive for methyl red?
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.
Why would a citrate-positive organism might not produce a color change in the simmons citrate agar?
A citrate-positive organism may fail to produce a color change in Simmons citrate agar due to insufficient incubation time. The color change is typically a slow process, and some organisms may require longer incubation periods to manifest this change. Additionally, certain strains of bacteria may lack the necessary enzymes to utilize citrate effectively, resulting in no color change despite being citrate-positive.
Why are many bacteria that are able to metabolize citrate produce negative results?
Many bacteria that are able to metabolize citrate do not produce a positive result on citrate utilization tests because they usually require specific conditions or mutations to express the necessary citrate transporter genes. In the absence of these conditions or mutations, the bacteria cannot transport citrate into the cell for metabolism, resulting in a negative test result.
What does citrate permease do?
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.
Aerobic Bacteria that is citrate positive VP negative and MR positive?
Bacillus megaterium
What is citrate phosphate dextrose?
Citrate phosphate dextrose (CPD) is a solution used in blood banking to store red blood cells. It contains citrate to prevent blood clotting, phosphate to regulate pH, and dextrose to provide energy to the cells during storage. CPD helps maintain the viability and function of red blood cells until they are needed for transfusion.
In CPDA-1 1 stands for?
citrate phosphate dextrose adenine
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
Is staphylococcus epidermidis citrate positive?
No, Staphylococcus epidermidis is typically citrate negative, meaning it cannot utilize citrate as a carbon source for growth. This characteristic can be used in biochemical tests to help differentiate it from other bacteria.
Does bacillus amyloliquifaciens have a positive reaction for citrate utilization?
Yes, Bacillus amyloliquifaciens typically shows a positive reaction for citrate utilization due to its ability to metabolize citrate as a carbon source. This can be confirmed using citrate utilization tests in a laboratory setting.
What are the different types of anticoagulants used in phlebotomy?
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)
Is bacillus cereus positive for methyl red?

What does the citrate metabolic test test for?
The citrate utilization test assesses an organism's ability to utilize citrate as a carbon source for growth. It is often used to differentiate between different species of bacteria, such as in differentiating between Citrobacter freundii and Salmonella species. If an organism can utilize citrate, it will demonstrate growth and turn the medium alkaline.
Bacillus cereus have a positive reaction for VP and citrate?
The B.cereus has a positive citrate test and a negative Voges Proskauer.
Why are many bacteria that are able to metabolize citrate produce negative results?
Many bacteria that are able to metabolize citrate do not produce a positive result on citrate utilization tests because they usually require specific conditions or mutations to express the necessary citrate transporter genes. In the absence of these conditions or mutations, the bacteria cannot transport citrate into the cell for metabolism, resulting in a negative test result.
