For what purpose seaweed is used?

Question

I have seen it being used for making fruit jellies. I'd like to know its other uses.

What's sushi?

Answer 1

Dried and fresh seaweed can be used in foods such as sushi, or even eaten plain as snacks. Some cards are made with pressed dried deaweed.

Algin, derived from seaweed is used in many things, makeup, soap, fertilizers, store bought ice cream, toothpaste, shampoos

Agar, the clear coating similar to gelatin on the bottom of some petrie dishes (when put there by a teacher or researcher, of course!! ) is a nutrient rich food used to culture bacteria for experiments.

Seaweed is also found in five major types of mdedication those used to treat tuberculosis, arthritis, colds, influenza and worm infections.

Wow! Way more thinks that you thought, huh? :-)

Answer 2

Nonliving seaweed biomass can be used in the development of biosorbent materials to accumulate heavy metals. The biomass, in this case, must be selective, reusable and cheap, thus constituting an alternative technology for residual metal ions recovery. Non living biomass of seaweeds can be used for this purpose, being an efficient treatment for heavy metals contaminated effluents.

For the uptake of heavy metals two different reactor configurations can be used: continuous stirred tank reactor and fixed bed columns.

Even though the literature presents papers using bacteria (da Costa and Duta, 2001), algal cells (Schmitt et al. 2001), fungi (McAfee et al. 2001) and other biomaterials (Lister and Line, 2001; Schneider et al. 2001), little is known about the behavior of a continuous system, for this kind of treatment. The purpose of the present work was to investigate the behavior of continuous serial reactors for the uptake of zinc. As well, little is known about ion-exchange properties of the biomass. Most papers describe this process as a typical adsorption process, not investigating the possible involvement of ion-exchange reactions (Esposito et al. 2001; Hatzikioseyian et al. 2001).

The brown seaweed Sargassum sp. is mainly constituted by the polysaccharide alginate, usually calcium and sodium alginates, thus with a high potential for the accumulation of heavy metals, as compared to other algal genera (da Costa and de França, 1996). Those polysaccharides are produced due to the interaction between alginic acid and alkaline and alkaline-earth elements from seawater. Those elements constitute efficient ion-exchangers for heavy metals present in solution. On the other hand, calcium, when in solution, is usually present due to precipitation with calcium salts, performed during primary effluent treatment.

The objective of the present work was to evaluate zinc and calcium biosorption by Sargassum sp., and also to evaluate the release of light metals from the structure of the biomass, due to ion-exchange reactions, in a continuous laboratory system.

Answer 3

It's in a lot of medicines and also food. You can make toothpaste from seaweed too! There is so much more. I don't know them all, but I do know that seaweed is pretty awesome if you think about it.

Answer 4

good day Enki! :-) Ha! You did no longer state which form of cactus, so i'm assuming i ought to chosen? i could be a Christmas cactus (additionally prevalent as Orchid Cactus) that are shared by potential of many human beings on Christmas Eve! this could be lots diverse to my familiar lifestyles type, as Christmas Cactus is community to Brazil! i could quite decide to have the capacity to hold excitement to somewhat toddler's face or enliven somebodies abode. this could imply my plant lifestyles are accessible in purple, pink, orange, purple, cream, fuchsia and so on..i could in all probability chosen purple, as purple and white are the colors of Christmas! i could additionally be enjoyed and properly cared for. As for seaweed, i've got by no potential been added or added each and every physique seaweed as a Christmas present, nor have I seen it putting interior somebodies abode. thank you! :-)

Answer 5

Some good replies,
but you and everybody else missed the obvious original intended purpose.

Sea life (fishes, starfish, sea urchin, shell fish) eat seaweed, hide and live among it.

Laboratory:
Agar petri plate for growing bacteria, fungi/yeast and plant tissue culture
Agarose gel electrophoresis
A temporary sealant

Answer 6

Alganate is used to make ice cream. So that it slows melting by making it clump up.
Agar is also used to make the medium that supplies for microorganisms in petri dishes.
Those fruit jelliies you were talking of are used primarily in Hotess fruit pies and donut fillings.

Answer 7

Seaweed is used in food preparation, medical, cosmetics, fertilization, and many more.

Answer 8

Seaweeds are extensively used as food by coastal peoples, particularly in East Asia, e.g. Japan, China, Korea, Taiwan, and Vietnam, but also in Indonesia, Peru, the Canadian Maritimes, Scandinavia, Ireland, Wales, Philippines, and Scotland, among other places. For example, Porphyra is a red alga used in Wales to make laverbread. In Asia, nori is a food composed of sheets of dried Porphyra and is used in soups or to wrap sushi. Chondrus crispus (commonly known as Irish moss or carrageenan moss) is another red alga used in producing various food additives, along with Kappaphycus and various gigartinoid seaweeds. Laverbread made from oats and the seaweed laver is a popular dish in Wales.

Seaweeds are also harvested or cultivated for the extraction of alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Agar is used in foods such as confectionery, meats and poultry products, desserts and beverages and moulded foods. Carrageenan is used in preparation of salad dressings and sauces, dietetic foods, and as a preservative in meat and fish products, dairy items and baked goods. Alginates enjoy many of the same uses as carrageenan, but are also used in production of industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
