What is the difference between aerobic and anaerobic fermentation?

• The main difference is the duration of the fermentation process.

• The main difference is the temperature at which fermentation occurs.

• The main difference is the presence or absence of oxygen.

• The main difference is the type of microorganisms involved.

How does fermentation contribute to the production of biofuels?

• Fermentation converts organic materials into biofuels.

• Fermentation increases the cost of biofuel production.

• Fermentation breaks down biofuels into organic materials.

• Fermentation produces toxic byproducts that are used as biofuels.
