Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
Does bacillus subtilis ferment acid from mannitol salt agar?
In my result i isolate bacillus sp on mannitol salt agar but i expect that this media has deoration or expaired
How do mannitol-salt agar tests work?
Mannitol salt agar supports growth of organisms that can grow in a high salt concentration, particularly Staphylococcus species and halophiles. The phenol red pH indicator in the agar will also let you know whether or not the bacterium you streaked ferments mannitol by changing to a yellow color if fermentation has occured.
Does E. faecalis test positive for MSA agar test?
yes it will ferment the mannitol and cause yellow color change.
Does s. epidermidis grow on msa?
Streptococcus cannot grow on MSA plates because MSA is a selective and differential media. It is selective because only certain microorganisms can grow on it due to its high NaCl content, in which this concentration - near 10% in MSA - has an inhibitory effect on most bacteria, such as Streptococci.
Can Klebsiella pneumoniae grow on Mannitol salt agar?
No, K. pneumoniae will not grow on Mannitol Salt Agar- gram negative organisms cannot grow on MSA, and K. pneumoniae is gram negative.
Can enterobacter aerogenes grow on mannitol salt agar?
the bacteria dont ferment in MSA, there is no growth on the plat
Can Streptococcus grow on MSA?
MSA stands for mannitol salt agar. Streptococcus can not grow on this type of agar. This is because it has a very high salt content, which allows only certain microorganisms to grow in it.
Why is mannitol salt considered to be a differential media?
Mannitol salt agar is used for the isolation of staphylococci which is found normally on skin (S. aureus). The selectivity is obtained by the high salt concentration that inhibits growth of many groups of bacteria.
Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
Do Gram negative organisms grow on MSA plates?
Yes
Which ingredient in mannitol salt agar supplies carbon?
mannitol is a type of sugar, so it supplies the carbon in the MSA medium
Can serratia marcescens grow in mannitol salt agar?
No it doesn't because it doesn't ferment mannitol. P. mirabilis can actually grow on a MAC agar, but it is colorless. I actually had this lab in Micro260 today.An MSA agar has 7% high salt concentration and provides growth for S. aureus bacteria turning it yellow/gold. An MSA agar is selective for osmotolerant bacteria meaning for bacteria that can grow in different salt concentrations, and it's differential because it can ferment mannitol.
