Uses of marine species of algae

Alge su široka skupina uglavnom vodenih fotosintetskih organizama koje s obzirom na dimenziju talusa postoje kao makroalge te planktonske mikroalge i široko su rasprostranjene u vodenim ekosustavima. Biomasa morskih vrsta algi predstavlja vrijednu sirovinu za cijelokupno čovječanstvo. Imaju veliku prehrambenu korist, tradicionalno se koriste kao hrana na Dalekom Istoku, a sve više i u drugim zemljama, gdje se većinom crvene (Rhodophyceae) i smeđe (Phaeophyceae) alge mogu naći u obliku ekstrakata (agara, alginata i karagenana) u gotovim proizvodima. Njihovo bogatstvo različitim organskim molekulama ima pogodan učinak na zdravlje i omogućuje da se koriste u obliku suplemenata, te alternativno za liječenje mnogih bolesti. Omekšavaju, umiriju kožu, a djeluju i antioksidativno stoga su dio mnogih kozmetičkih proizvoda za kožu i kosu. Sadrže za tlo i biljke važne elemente pa se od njihovih ekstrakata proizvodi i biognojivo, a algino brašno se koristi u prehrani stoke. Ovi organizmi imaju sve veći potencijal u proizvodnji biogoriva u nadi da će zamijeniti fosilna goriva, no to je još uvijek izazov budućnosti. Nadalje, njihova sposobnost akumuliranja toksičnih tvari i mogućnost upotrebe u pročišćavanju voda još uvijek je u fazi istraživanja.Algae are broad group of water based photosynthetic organisms which regard to dimension of thallus exist as macro algae and plankton micro algae which are broadly widespread in underwater ecosystem. Biomass underwater spieces of algae presents valuable raw material for whole humanity.It has huge nutritive value, traditionaly its used as food on the Far East and more and more in other countries where mostly red (Rhodophyceae) and brown (Phaeophyceae) algae can be found in form of extract (agar, alginate and carrageenan) in finished products.Being rich in content of various ogranic molecules that has beneficial effect on health and it issuitable to be used as suplements, also its good for alternative way of healing many diseases.They have softening and calming effect on skin, aslo having antioksidant properties makesthem part of many cosmetics products for skin and hair. Containing important elements for soil and plants makes good use from their extract to produce biofertilizer and algal flour which is used for feeding livestock.These organism have more and more potencial in production of biofuels in hope that they will replace fosil fuels but that is still just challange of future.Their ability for accumulating toxic substances and for filter water is still in phase of research
