Without using chemical agents, name two examples of how the bacterial cell wall can be damaged that would result in Gram-positive bacteria showing a Gram-negative result
What will be an ideal response?
Gram-positive bacteria can show a Gram-negative result when the culture is too old or when bacteria produce endospores. Both of these result in damage to the cell wall as the bacteria get old and die or release the endospore.
