Question

question 17
this image shows motility media. which set of tubes represent the non - motile staphylococcus epidermidis?
○ a
○ b
○ both a and b

Explanation:

In motility media, non - motile bacteria like Staphylococcus epidermidis will not spread out from the line of inoculation, so the growth will be restricted to the inoculation line. Looking at the tubes, set B likely shows this restricted growth pattern (non - motile), while set A may show spread (motile). So the set representing non - motile Staphylococcus epidermidis is B.

Answer:

B
