Cellulose ethanol is used to make a biofuel. It is not used as a food source even though it comes from plant sources.Know More
Cellulose is grown all around the world. It is the fiber that is found in the stems, stalks and leaves of trees and plants. The ethanol that comes from it is an alternative source of biofuel. It is a superior source because it's expected to be energy efficient and less expensive than the ethanol from other sources. This is because it can be made out of the less expensive feedstocks, including wheat straw, rice straw, sawdust, forest thinning and grasses. Perennial grasses and switchgrass are particularly good sources for the ethanol.
The fungus Trichoderma reesei may be used to break the cellulose down into fermentable sugars for this purpose. The guts of termites are another viable option for this process as termites break down woody biomass to create sugars. Acid is something else that can be used to convert the cellulose to gas and then into biofuel. It is possible to convert the cellulose to sugars at a low cost. For this reason, many commercial applications are being planned at the moment. A U.S. ethanol producer named Broin plans to turn one of its corn-to-ethanol plants into a biorefinery for stover and corn grain.Learn More
According to Nature Education, restriction enzymes are used to cut DNA into smaller pieces that can then be separated by size via gel electrophoresis. Typical restriction enzymes cut DNA at four or six base pair recognition sites, resulting in very small pieces of DNA.Full Answer >
Carotenoids, a type of pigment, are used in photosynthesis to absorb sunlight for plants to convert into energy. Pigments are substances that absorb light in a specific spectrum. Carotenoids typically absorb light in the violet to green light spectrum, which is from about 400 to 550 nanometers.Full Answer >
Monocular microscopes, or single-eyepiece microscopes, are often used to study very small objects and organisms that can't normally be observed by the naked eye, such as cells, fungi and bacteria. These microscopes feature a magnification power typically ranging from 40x up to 1400x.Full Answer >
According to the CK-12 Foundation, protists are helpful to humans because they produce oxygen, are used in medical research, are an important part of the food chain and are even used in food. In fact, protists help to recycle the nutrients necessary for plant and animal life.Full Answer >
