At death phase,(Decline phase) bacteria die. This could be due to lack of nutrients, a temperature which is too high or low, or the wrong living conditions.

What do we know - why the bacteria actually die in the death phase? Some reasons are written there (for instance lack of nutrients), but can other reasons exist as well? For example can some toxins be generated that destroy bacteria?
