Photoorganoheterotroph = use light, organic e- donor, carbon source. Chemolithoautotroph = use organic/inorganic mlcls for energy, inorganic e- donor, CO2 carbon source. Chemolithoheterotroph = use organic/inorganic mlcls for energy, inorganic e- donor, organic carbon source. Chemoorganoheterotoph = organic/inorganic energy source, organic e- donor, carbon source.
When plastic polymer technology was not much in use Waxed Paper or card board paper was used to wrap soaps, cookies and a host of other fragile items. Wax makes the paper stiff, water resistant and moisture proof. Wax is environmentally benign and non toxic to humans. Even now as a green measure we see fruit juice packs on such cardboard papers.
Dichloromethane (DCM, or methylene chloride) is an organic compound with the formula C H 2 Cl 2.This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents.CM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. It is widely used as a paint stripper and a degreaser. In the food industry, it has been used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavorings.
