Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
What is a gram positive aerobic bacteria which uses citrate and dextrose?
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.
Is pseudomonas citrate negative?
positive
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.
Bacillus cereus have a positive reaction for VP and citrate?
The B.cereus has a positive citrate test and a negative Voges Proskauer.
Does serratia test negative for citrate?
Yes, Serratia marcescens typically tests negative for citrate utilization in citrate utilization tests. This bacterium lacks the enzyme citrate-permease needed to import citrate into the cell, resulting in a negative citrate test.
Which bacteria is NLF oxidase negative motile citrate and urease positive and TSI alkali nochange?
The bacteria described is likely to be Proteus species. Proteus is negative for oxidase, motile, and positive for citrate utilization, urease production, and TSI (triple sugar iron) test showing an alkaline/no change reaction. These characteristics are commonly associated with Proteus species.
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.
What gram negative facultative anaerobic bacteria are lipase negative and Simmons citrate negative?
E. Coli
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.
Is Shigella Positive for a citrate test?
Based on my own test, Shigella flexneri tests negative for the citrate test.
Is Morganella morganii positive for a citrate test?
Yes, Morganella morganii is positive for citrate utilization. This bacterium can use citrate as a carbon source for growth and will produce alkaline byproducts, causing a color change in the citrate test medium from green to blue.
