Yes, it is slightly manitol-positive, though. It will appear a medium yellow tint and Staphylococcus aureus will contrast it by turning bright yellow. S. aureus is a better example for mannitol-positive.

What else can I help you with?
What ingredient makes mannitol salt selective?
the salt content
Why is it important to differentiate glucose nonfermenters from enterobacteriaceae?
It is extremely important to differentiate glucose non fermenters from enterobacteriaceae. Enterobacteriaceae is a gram negative bacterium that can cause extreme illness if cross contaminated with a glucose non fermenter.
Why is the air trap necessary in fermentation?
so that the mixture in the fermenter is aerated and so that the air does not encourage the division of microorganisms such as bacteria.
Diffence between fermenter and fermentor?
The two are often used to refer to same thing. However, fermentor is the proper term for an apparatus, i.e. a bioreactor, while fermenter is the proper term for an organism that uses fermentation as a metabolic process, i.e. the thing that goes in the fermentor.
What are two substances that are sweet but are not sugars?
There are several "Sweet" chemicals, some of which are natural and some which are artificial. Of course there are items like corn syrup, honey etc...but they are actually sweet because of naturally occurring sugars so that does not really count. Some artificial substances include things like aspartame or sucralose. Natural sweet substances include proteins such as brazzein and monellin and pentadin as well as alcohols such as malitol, mannitol, and sorbitol.
Can salmonella typhimurium grow on mannitol salt agar?
No, Salmonella Typhimurium cannot grow on Mannitol Salt Agar because it is a selective and differential media primarily used for isolating and differentiating Staphylococcus species based on their ability to ferment mannitol. Salmonella Typhimurium is not a mannitol fermenter, so it will not grow on this agar.
From what specimen type would S saprophyticus most likely be isolated?
S. saprophyticus is the second most common cause of UTI - therefore you could isolate this from a urine sample.
Can bacillus subtilis grow on msa?
Bacillus subtilis is generally able to grow on Mannitol Salt Agar (MSA) because it is a non-fermenter of mannitol. Most Bacillus species, including B. subtilis, are not able to ferment mannitol, so they can grow on MSA but will not change the color of the agar.
Is staphylococcus saprophyticus MOTILITY positive?
No, Staphylococcus saprophyticus is non-motile.
What is S. saprophyticus?
Staph bacteria. Existing within and around the.(urethra) of about 5% of healthy males and females, S. saprophyticus is the second most common cause of unobstructed urinary tract infections (UTIs) in sexually active young women.
What are the various types of fermenter?
Fermenter are of two types 1. Aerobic fermenter 2. Anaerobic fermenter
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.
What is the principle of mannitol fermentation?
Mannitol fermentation have high levels of NaCl (7.5%) which inhibit most organism other than staphylococci aureus, contains D-mannitol, pH indicator called 'phenol red' which detect the acid production in mannitol . It also differentiate S. aureus and S. epidermidids .
Can staphylococcus saprophyticus cause urinary tract infections?
Existing within and around the tube-like structure that carries urine from the bladder (urethra) of about 5% of healthy males and females, S. saprophyticus is the second most common cause of unobstructed urinary tract infections
Why is only mannitol used in ashby's mannitol broth?
MANNITOL IS CARBON SOURCE & AZOTOBACTER can fix nitrogen non- symbiotically
HOW do mannitol salt hook up to glycolysis?
Mannitol is not a substrate for glycolisis
Does Saccharomyces cerevisiae ferment mannitol?
Mannitol salt agar inoculated with Micrococcus luteusshowing no fermentation of mannitol (pink medium). The colonies show a yellow pigment which is characteristic of M. luteus.
