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.
Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints. Two of the most familiar chlorine compounds are sodium chloride (NaCl) and hydrogen chloride (HCl). Sodium chloride, commonly known as table salt, is used to season food and in some industrial processes. Hydrogen chloride, when mixed with water (H2O), forms hydrochloric acid, a strong and commercially important acid.
