Lab 5: Fermentation and Biofuels Flashcards
Fermentation
The process of producing ethanol through the breakdown of carbohydrates by yeast.
Ethanol
A type of alcohol produced through fermentation, commonly used as a biofuel.
Biological efficiency
The measure of how efficiently the fermentation process produces ethanol.
Data analysis
The process of interpreting and drawing conclusions from experimental data.
Biofuels
Alternative sources of energy, such as ethanol and biodiesel, produced from organic materials.
Sustainable
Environmentally friendly and capable of being maintained over the long term.
Environmentally friendly
Having a minimal impact on the environment.
Investments
Allocations of money or resources for the purpose of generating future income or benefits.
Biodiesel
A type of biofuel made from vegetable oils or animal fats.
Refineries
Facilities where raw materials are processed to produce usable products.
Renewable Fuel Standard Program
A program aimed at increasing the production of renewable fuels, such as corn ethanol.
Net energy gain
The amount of energy gained from a process after accounting for the energy input required.
Eutrophication
The excessive growth of algae and other aquatic plants due to the presence of nutrients in water bodies.
Groundwater
Water located beneath the Earth’s surface, often used as a source of drinking water.
Aquatic ecosystems
Ecosystems found in bodies of water, such as lakes, rivers, and oceans.
Herbicides
Chemicals used to kill or inhibit the growth of unwanted plants.
Fertilizers
Substances added to soil or plants to provide essential nutrients for growth.
Greenhouse gases
Gases, such as carbon dioxide and methane, that trap heat in the Earth’s atmosphere.
Carbon-neutral
Not contributing to the increase of greenhouse gases in the atmosphere.
Sugarcane
A tall perennial grass used for the production of sugar and ethanol.
Greenhouse gas emissions
The release of gases that contribute to the greenhouse effect and global warming.
