In biscuit making, use of chlorinated flour reduces the spread of the dough, and provides a "tighter" surface. The changes of functional properties of the flour proteins are likely to be caused by their oxidation. In countries where bleached flour is prohibited, microwaving plain flour produces similar chemical changes to the bleaching process ...
"Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, [citation needed] removed and is often referred to as "white flour". Bleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both.
Photobleaching: The movie shows photobleaching of a fluorosphere. The movie is accelerated, the whole process happened during 4 minutes. In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce.
One design optimum is a natural ecosystem which is designed for a special purpose like a sewage treating wetland in a suitable ecosystem for the locality. Another optimum is an economically viable system returning profit for the investor. The practice of permaculture is one example for a compromise between the two optimum design points.
An example of a topological food web (image courtesy of USDA) [1] The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Photoheterotrophs generate ATP using light, in one of two ways: [6] [7] they use a bacteriochlorophyll-based reaction center, or they use a bacteriorhodopsin.The chlorophyll-based mechanism is similar to that used in photosynthesis, where light excites the molecules in a reaction center and causes a flow of electrons through an electron transport chain (ETS).
Yellow slime mold growing on a bin of wet paper. Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. [a] [2] It is generally assumed to be a natural process, which differentiates it from composting.
