Yes, P. vulgaris is a lactose non-fermenter. It does not possess the enzyme beta-galactosidase needed to ferment lactose into glucose and galactose. Instead, it typically ferments sugars like glucose and sucrose.

What organism found in urine culture is gram negative rods and lactose fermenter?
The organism likely to be found in a urine culture that is a Gram-negative rod and a lactose fermenter is Escherichia coli. E. coli is a common cause of urinary tract infections and is characterized by these microbiological properties.
Give result lactose test for bacteria citrobacter diversus?
Citrobacter diversus is capable of fermenting lactose, therefore it would test positive for lactose fermentation in biochemical tests. This bacterium produces acid and gas during lactose fermentation, which can be detected using appropriate methods such as the MacConkey agar test.
Is proteus vulgaris a coliform bacteria?
Yes, Proteus vulgaris is considered a coliform bacteria because it is a Gram-negative, facultative anaerobe that can ferment lactose. Coliform bacteria are a group of bacteria used as indicators of water quality and fecal contamination.
Does Proteus vulgaris have a capsule?
Yes, Proteus vulgaris can have a capsule, which is a protective layer outside the cell wall. The presence of a capsule in P. vulgaris can contribute to its virulence and ability to evade the host's immune system.
Can proteus vulgaris grow on msa?
Proteus vulgaris typically does not grow well on Mannitol Salt Agar (MSA) because it is a non-fermenter of mannitol and cannot utilize this substrate. MSA is selective for salt-tolerant organisms like Staphylococcus species, which can ferment mannitol, resulting in a pH decrease and color change. Proteus vulgaris is more commonly found on media like MacConkey agar.
Is E. coli lactose fermenter?
yes it is lactose positive
Is serratia a lactose fermenter?
Yes, Serratia is a facultative anaerobe and can ferment lactose.
Most recent research on P vulgaris?
what is the most recent research there is on P. vulgaris?
Is hafnia a lactose fermentor?
Yes, Hafnia is a lactose fermenter. It is a Gram-negative bacterium which can ferment lactose to produce acid and gas. This characteristic can be used for its identification in microbiology.
What organism found in urine culture is gram negative rods and lactose fermenter?
The organism likely to be found in a urine culture that is a Gram-negative rod and a lactose fermenter is Escherichia coli. E. coli is a common cause of urinary tract infections and is characterized by these microbiological properties.
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).
Give result lactose test for bacteria citrobacter diversus?
Citrobacter diversus is capable of fermenting lactose, therefore it would test positive for lactose fermentation in biochemical tests. This bacterium produces acid and gas during lactose fermentation, which can be detected using appropriate methods such as the MacConkey agar test.
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
Is proteus vulgaris a coliform bacteria?
Yes, Proteus vulgaris is considered a coliform bacteria because it is a Gram-negative, facultative anaerobe that can ferment lactose. Coliform bacteria are a group of bacteria used as indicators of water quality and fecal contamination.
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
Does Proteus vulgaris have a capsule?
Yes, Proteus vulgaris can have a capsule, which is a protective layer outside the cell wall. The presence of a capsule in P. vulgaris can contribute to its virulence and ability to evade the host's immune system.
