Biofuel

Definition

Biofuel is a type of energy source derived from organic material, such as plant or animal waste. It is produced through biochemical processes including fermentation by microbes.

5 Must Know Facts For Your Next Test

1. Biofuels can be produced using microbial fermentation, where microbes break down organic matter to produce ethanol or other fuels.
2. Microbes like yeast and bacteria are essential in the biofuel production process due to their ability to ferment sugars into ethanol.
3. Fermentation for biofuel production occurs under anaerobic conditions, meaning it takes place without oxygen.
4. The efficiency of microbial fermentation for biofuel depends on factors such as temperature, pH, and the type of microbe used.
5. Biofuels are considered renewable energy sources because they can be continuously produced from organic materials.
