Seaweed preparation

Though many soil amendments are available for organic farming, these materials must be naturally based. In addition to manure-based fertilizers, many organic farmers rely on fish emulsion and seaweed preparations to supply nitrogen and other...

Fluorine comes from the minerals fluorspar, CaF, cryolite, Na3AlF6 and the fluorapatites, Ca,F(P04)3. The free element is prepared from HF and KF by electrolysis, but the HF and KF needed for the electrolysis are prepared in the laboratory. Chlorine primarily comes from the mineral rock salt, NaCl. The pure element is obtained by electrolysis of liquid NaCl. Bromine is found in seawater and brine wells as the Br ion it ts also found as a component of saline deposits the pure element is obtained by oxidation of Br (aq) by Cl,(g). Iodine is found in seawater, seaweed, and brine wells as the I" ion the pure element is obtained by oxidation of I (aq) by Cl,(g). 

To date there is no evidence that the toxins of L. ma.iuscula are involved in the development of human cancer. Certainly frequent ingestion of edible seaweeds that are contaminated with L. ma.1uscula could increase the probability of gastrointestinal cancer. There is precedence for this. The black and Creole population of the Caribbean island of Curacao suffers from an exceedingly high rate of esophageal cancer which appears to be related to the daily intake of a tea prepared from the leaves of a... 

By inserting hydrophobic antiobesity compounds into the liposomal bilayers, marine phospholipids would boost the effect of the inserted hydrophobic antiobesity compounds. When marine phospholipids are served as liposomal drinks, they would be more effective than adding into solid foods or feeds. These facts were borne out by Okada et al. (2011). They carried out the following experiment. Brown seaweed (Undaria pinnatifida) lipid containing fucoxanthin (UL) encapsulated into scallop midgut gland phospholipids (PL) liposomes were prepared to see the promotional effect of marine phospholipid liposome on antiobesity. Animal model used in their study was 3-week-old male diabetic-obese... 

Agarose, a product extracted from seaweed, is a linear polymer of galac-topyranose derivatives. Gels are prepared by dissolving agarose in warm elec-... 

Iodine Iodine is a volatile purple-black solid with a beautiful metallic sheen. As the least reactive halogen, iodine is safe to handle and is widely used as a skin disinfectant. It was first prepared in 1811 from seaweed ash, but commercially useful deposits of the iodine-containing minerals lautarite (CaIC>3) and dietzeite [7 Ca( 103)2 8 CaCr04] were subsequently found in Chile. Iodine is used in the preparation of numerous organic compounds, including dyes and pharmaceutical agents, but there is no one single use of major importance. 

Barry and Dillon184 prepared a polysaccharide from the red seaweed Rhodymenia palmata by extracting the plant with dilute hydrochloric acid and precipitating the product with alcohol. This substance gave...
