The rate of bacterial growth is assessed by the doubling time, the period required for the number of cells to double.

The shorter the doubling time, the faster the bacteria are growing.

Escherichia coli growth rates can range from doubling times as fast as 18 minutes to slower than 180 minutes.

formation of ROS in two condition;
a) Mitochondria are not making ATP (for lack of ADP or O2) and therefore have a large proton-motive force and a high ratio of QH2/Q
b) there is a high NADH/NADratio in the matrix
