Can B subtilis grow on MSA?

No, Bacillus subtilis cannot grow on Mannitol Salt Agar (MSA) as it cannot ferment mannitol and does not tolerate the high salt concentration in MSA. MSA is selective for Staphylococcus species that can ferment mannitol.


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.


Why wouldn't it be advisable to compare growth of the organisms on each plate to each other in MSA plate?

Comparing the growth of organisms on Mannitol Salt Agar (MSA) plates is not advisable because MSA selects for specific types of bacteria, primarily halophiles and Staphylococci, which can lead to misleading interpretations of growth patterns. Additionally, the agar contains mannitol, which some bacteria ferment while others do not, resulting in different color changes that can further complicate direct comparisons. Variations in growth rates and colony morphology can also result from differences in physiological properties, making it difficult to draw accurate conclusions about their relative growth.


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.


What organisms do not grow on msa and mannitol?

Organisms that do not grow on Mannitol Salt Agar (MSA) are non-halophilic bacteria that are unable to tolerate high salt concentrations. Mannitol-fermenting bacteria are organisms that can ferment mannitol and grow on MSA, while non-fermenting bacteria will not grow.

Does micrococcus luteus grow on msa plates?

Yes micrococcus luteus, along with micrococcus roseus both grow on MSA. But, they do not fermente on this agar giving a negative test. However, Staphylococcus aureus grows on MSA and fermentes giving a positive test. *Side note* MSA plate is used to test for G+ coccus. The plate contains salt and salt "loving" bacteria will grow and show yellow colony, example of S. aureus.

What is the principle behind the functioning of a zone-plate in optics?

A zone plate in optics works based on the principle of diffraction, where light waves are bent and focused by alternating transparent and opaque zones on the plate. This creates interference patterns that concentrate light to form an image or focus it at a specific point.
