This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.

In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.
