Question

Does Bacillus subtilis ferment glucose?

Answer 1

Bacillus subtilis:

1. Bacillus subtilis are gram-positive, rod-shaped bacteria that naturally occur in soil and grow in moderate temperature ranges.
2. It is utilized as a feed additive in agriculture and employed in animal husbandry to enhance fiber digestion and intestinal health in animals.
3. It improves the balance of intestinal flora, promotes intestinal health, and increases food absorption efficiency.
4. It is a facultative anaerobe that is capable of fermenting glucose.
5. Fermentation of glucose begins with glycolysis but does not involve the Krebs cycle and oxidative phosphorylation.
6. Glycolysis is a series of cellular reactions that generate energy by splitting glucose into pyruvate molecules. It is the first step of aerobic respiration.
7. In glycolysis, the NAD+ electron carriers are reduced to form two NADH molecules and two ATP molecules.
8. It converts one glucose molecule into two pyruvate molecules and yields two ATP and two NADH molecules.
9. This NADH is further oxidized to form ATP molecules.
