Algal biomass

Definition

Algal biomass refers to the total mass of algae, which includes various species of aquatic photosynthetic organisms, produced in a given area over a specific time period. This biomass is significant because it serves as a renewable resource that can be harvested for various applications, including biofuels and other sustainable products that contribute to reducing reliance on fossil fuels.

5 Must Know Facts For Your Next Test

1. Algal biomass can grow rapidly and is highly efficient at converting sunlight and carbon dioxide into usable energy, making it a promising source of renewable energy.
2. Different types of algae, such as microalgae and macroalgae, have varying compositions that can be utilized for biofuel production, animal feed, or even pharmaceuticals.
3. Algal cultivation requires less land and freshwater compared to traditional crops, thus offering a more sustainable option for biomass production.
4. The lipids extracted from algal biomass can be processed into biodiesel, while carbohydrates can be converted into bioethanol or biogas.
5. Utilizing algal biomass not only helps produce clean energy but also contributes to reducing greenhouse gas emissions through carbon dioxide absorption during growth.
