Biohydrogen production from microalgae

Zbog ograničenih zaliha i doprinosa akumulaciji ugljikovog dioksida u okolišu kontinuirana upotreba fosilnih goriva smatra se neodrživom. Za ekonomsku i ekološku održivost ljudskoj vrsti je potrebno obnovljivo gorivo. Mikroalge predstavljaju vrijednu sirovinu za proizvodnju prehrambenih, farmaceutskih i kozmetičkih proizvoda (vitamina, antioksidansa, bjelančevina, masnih kiselina, pigmenata, imuno stimulansa i lijekova) te proizvodnju biogoriva. Učinkovita proizvodnja biovodika iz mikroalgi povezana je s odabirom vrste, odgovarajuće hranjive podloge, uvjeta i postupaka vođenja bioprocesa u bioreaktorskim sustavima, metodama izdvajanja vodika i počišćivanja biomase, odnosno lipida iz biomase mikroalgi. U radu je opisana proizvodnja biovodika iz mikroalgi i njihova praktična primjena.Continued use of fossil fuels has been recognized as unsustainable because of exhausting stocks and their contribution to the accumulation of carbon dioxide in the environment. For economic and environmental sustainability human race needs a renewable, CO2 neutral transportation fuel. Microalgal biomass represents valuable raw material for food, pharmaceuticals, and the cosmetic industry (vitamins, antioxidants, proteins, fatty acids, pigments, immunostimulants, and pharmaceuticals) as well as for biofuels production. The efficient production of biohydrogen from microalgae biomass is associated with a selection of microalgae, an appropriate culture medium, conditions, and procedures of keeping the bioprocess bioreactor systems, biomass and lipids separation and purification methods. This thesis comprehends biohydrogen production and practical application of microalgal biomass
