A strictly fermentative bacterium produces its energy (ATP) by glycolysis only.

Here's the step by step process:

1. Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. This process occurs in the cytoplasm of the cell and does not require oxygen.

2. In glycolysis, one glucose molecule is broken down into two molecules of pyruvate. This process also produces a net gain of two ATP molecules and two NADH molecules.

3. Since the bacterium is strictly fermentative, it does not use aerobic respiration to produce ATP. Instead, it relies on fermentation.

4. In fermentation, the pyruvate and NADH produced in glycolysis are used to regenerate NAD+, which is needed for glycolysis to continue. This process does not produce any additional ATP.

5. Therefore, all of the bacterium's ATP is produced in glycolysis, and none is produced in the absence or presence of oxygen.
