Give result lactose test for bacteria citrobacter diversus?
lactose fermenter
What organism found in urine culture is gram negative rods and lactose fermenter?
E. coli
Is proteus vulgaris a coliform bacteria?
no it does not ferment lactose, therefore is not a coliform
Why do some bacteria produce a green metallic sheen on EMB agar?
Because it releases acid and gas when it ferments the lactose on the plate, which causes a color change of the colony. E. coli is a heavy lactose fermenter. This is similar to how when E. coli is grown on MacConkey agar, the colonies turn bright pink compared to a regular lactose fermenter which turns light pink and a non-lactose fermenter which is cream colored. The acid is causing a drop in pH and a reaction with the dye is occurring.
What bacteria are non-lactose ferment er?
Mnemonic: KEE Klebsiella pneumoniae Enterobacter cloacae E. coli Shigella sonnei can ferment lactose, but only after prolonged incubation and so it is referred to as a '''''late-lactose fermenter'''''. Vibrio cholerae is also a late lactose fermenter.
Is serratia a lactose fermenter?
no
Is E. coli lactose fermenter?
yes it is lactose positive
Give result lactose test for bacteria citrobacter diversus?
lactose fermenter
Most recent research on P vulgaris?
what is the most recent research there is on P. vulgaris?
What organism found in urine culture is gram negative rods and lactose fermenter?
E. coli
Is proteus vulgaris a coliform bacteria?
no it does not ferment lactose, therefore is not a coliform
Can Pseudomonas fluorescens grow on MacConkey agar?
Yes. But because it is not a lactose fermenter, the colonies will be colorless (or sometimes have a green tint).
Can shigella sonnei be a lactose non fermenter My tests are as followed TSI KA Methyl red VP - citrate - urea - NO3 degraded to NO2 H2S - motility -. all points to shigella but it's nonferm?
S.sonnei is not a true lactose fermenting bacteria (see.. http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=271578&blobtype=pdf)But is a delayed lactose fermenter as it does not have the enzyme permease to transport lactose through its cell wall.However an ONPG lactose fermenting test does not require permease to allow the bacterium to ferment lactose so in an ONPG test the shigella sonnei will appear as lactose fermenting positive.Hope this helps!!2nd year BMS student
Does proteus mirabilis ferment lactose?
No.----------------------------------------------------------Disagree. You'll find a positive sucrose fermentation test for P. vulgaris at MicrobeLibrary.org. The site is an affiliate of the American Society of Microbiology, so I'm guessing it's a safe bet.
What are the various types of fermenter?
Fermenter are of two types 1. Aerobic fermenter 2. Anaerobic fermenter
