The incubation time is important because however long your culture is kept in incubation affects how many colonies you will have at the end. A short incubation time will result in minor bacterial growth, whereas a longer incubation will result in more colonies, as you're giving the bacteria more time to grow. Be careful, if you leave your culture in incubation for too long, the bacteria will begin to use up all of the agar and start competing for food resources. If left even longer, this will consequently result in the death of your culture.
If incubation surpasses 5 days, the bacteria may degrade indole to the point that a FALSE negative would result.
is behavior a result of culture or heredity
1. It is less likely to get a false positive result. Usually the test can detect the pure organism right away. It is therefore acceptable to record positive test before suggested incubation time is completed. A negative result should not be recorded early because sometimes it takes longer for bacteria to hydrolyze the material.
Yes, I think so. I am not a professor but it seems obvious to me. Culture is also representative of the community so it is an end result of a community as well as a constant stimulus. Can have one without the other. Culture is by definition a result of a community. No culture, no community. No community, no culture.

The kind of culture that Turkey has at the moment is a mixed culture. This is as a result of interaction with other cultures especially in urban centers.
