Kelp Origins and Classes.
Kelp refers to any of numerous large seaweeds found in colder seas and belonging to the order Laminariales (about 30 genera) of brown algae. The term applies also to the ash produced by the incineration of various seaweeds.
Until early in the 19th century this ash was an important source of potash (derived from the plant's stemlike stipe) and iodine (extracted from its leaflike blades). Giant kelp, of the genus Macrocystis, is rich in minerals and produces algin, a complex carbohydrate (polysaccharide) that is useful in various industrial processes, including tire manufacture. Algin is added to ice cream before freezing to prevent crystallization and is also used as a suspending and emulsifying agent.
Different kinds of kelp have been eaten for nutritional value for over a thousand years. The Chinese used kelp and other types of seaweed as medicine as far back as 3,000 B.C. The Greeks used kelp to feed their cattle around the first century B.C. Kelp has been a staple food of Icelanders for centuries, and ancient Hawaiian nobles grew gardens of edible seaweed. Kelp was also used in Europe and Great Britain as fertilizer to nourish soil and assist plant growth.
The largest consumer of kelp, however, has been China. The Chinese have incorporated kelp and seaweed into their diets for 1,500 years. During the seventh to ninth centuries, only the nobility consumed seaweed. In the seventeenth century, China began farming seaweed. The Asian cultures used kelp to treat uterine problems, genital tract disorders, and kidney, bladder, and prostate ailments.
Kelp is still an integral part of the diet. The Chinese include kelp in almost every meal, using it in salads or as a garnish, or cooking it in soups, sauces, and cakes. Noodles made from kelp are a staple of the diet. Until recently, kelp was eaten almost exclusively by the Chinese. Now the Western population is beginning to take note of this nutrient-rich seaweed. However, Fucus vesiculosus is not the kind of kelp that is eaten.
Eating dietary kelp may be responsible for the low rate of breast cancer among women, and also for the low rate of heart disease, respiratory disease, rheumatism, arthritis, high blood pressure, and gastrointestinal ailments. The occurrence of thyroid disease is also low.
Several genera of brown algae are known as kelp. Laminaria, a large brown seaweed (1 to 3 m long) abundant along the Pacific coasts and the British Isles, is a source of commercial iodine and produces acetic acid when allowed to ferment. It has a stipe that superficially resembles the stem of land plants and lives several years, but the blade dies each year. Growth occurs, as in all kelp, at the meristematic region between the stipe and the blade.
Macrocystis, the largest known kelp, up to 65 m long, is limited in distribution because it reproduces only at temperatures below 18~20 degree C. The complicated plant body, similar in appearance to that of higher plants, has a large rootlike holdfast for attachment to the ocean floor, a hollow stemlike stipe for the internal transport of organic material, and a long branching stalk with blades that stay afloat by means of hollow gas bladders.
Nereocystis, or sea otter's cabbage, an annual kelp that grows primarily in deep waters and rapid tideways, can attain lengths up to 40 m. Internally the plant structure is similar to Macrocystis. Externally the stalk is tough and whiplike, terminating in a large bladder. The long leafy outgrowths from the stalk carry out photosynthesis and reproduction.
Characteristics: The brown colour of these algae results from the dominance of the xanthophyll pigment fucoxanthin; this masks the other pigments, Chlorophyll a and c (no Chlorophyll b), beta-carotene and other xanthophylls. Food reserves are typically complex polysaccharides, sugars and higher alcohols; the principal carbohydrate reserve is laminaran. and true starch is absent (compare with the green algae) The walls are made of cellulose and alginic acid, a long-chained heteropolysaccharide. There are no known unicellular or colonial representatives of this group; the simplest form of plant is a branched, filamentous thallus. The kelps are the largest (up to 70 m long) and the most complex brown algae and they are the only algae known to have internal tissue differentiation into conducting tissue; there is, however, no true xylem tissue as found in the 'higher' plants. The vast majority of the Phaeophyta are marine in distribution.
Life history: Most brown algae have an alternation of haploid and diploid generations. The haploid thalli form isogamous, anisogamous or oogamous gametes and the diploid thalli form zoospores by meiosis. The haploid (gametangial) and diploid (sporangial) thalli may be similar (isomorphic) or different (heteromorphic) in appearance, or the gametangial generation may be extremely reduced (Fucales).
Utilization:
About 26,000 tonnes of the brown kelp Macrocystis pyrifera are harvested each year off the coasts of California, Mexico and Chile for extraction of alginic acid. This is used commercially for toothpastes, soaps, ice cream, tinned meats, fabric printing, and a host of other applications. It forms a stable viscous gel in water, and its primary function in the above applications is as a binder, stabilizer, emulsifier, or moulding agent. About 16,000 tonnes of Ascophyllum nodosum (Feamainn bhui in Irish, referring to the yellow colour in summer) is harvested each year in Ireland, dried and milled in factories at Kilkerrin, Co. Galway; and about 3,000 t of the resulting seaweed meal is exported and processed in Scotland for the production of alginic acid.
Laminaria hyperborea stipes (sea rods) are also harvested in Norway and used to be collected in drift in Scotland and Ireland. The rods are used for the manufacture of high-grade alginates. Other brown algae are used for the extraction of agricultural sprays ('liquid seaweed extracts'). These extracts are used at low concentrations on crops and their hormone-like activities are thought to be due to betaines, cytokinenins, etc.
There are about 1800 species of brown algae, and most are marine. In general, brown algae are larger and more species are found in colder waters and virtually all the biomass worldwide comes from a relatively small number of species in the orders Laminariales and Fucales.
