A digestate was used from a biogas plant producing biogas from various organic materials such as animal skins, waste edible oils, animal by-products, and expired foodstuffs. The study took place for 14 days under laboratory conditions. The results showed that the digestate used had low amounts of nutrients and was therefore less suitable for algae growth. The green microalgae C. vulgaris has proved to be significantly more effective in the removal of nutrients from digestate than an algal mixture. In C. vulgaris samples 94% reduction in phosphates and 23% reduction in nitrates was achieved, while in the algal mixture the content of phosphates decreased only by 14%, with an increase in nitrates. The reason could be the poor condition of the mixed algal culture and inappropriate selection of algae species</dc:description><dc:description xml:lang="sl">V prispevku smo raziskovali učinkovitost čiščenja digestata s pomočjo zelene mikroalge Chlorella vulgaris in mešanice treh vrst zelenih mikroalg. Za raziskavo smo uporabili digestat iz bioplinarne, ki za proizvodnjo bioplina uporablja različne organske materiale, kot so živalske kože, odpadna jedilna olja, živalski stranski proizvodi in živila s pretečenim rokom uporabe. Raziskava je potekala 14 dni v laboratorijskih pogojih. Rezultati so pokazali, da je bila vsebnost hranil v uporabljenem digestatu majhna, zato je bil ta manj primeren za uspevanje alg. Zelena mikroalga C. vulgaris se je izkazala za znatno bolj učinkovito za odstranjevanje hranil iz digestata kot mešana kultura alg. V vzorcih s C. vulgaris smo dosegli 94 % zmanjšanje fosfatov in 23 % zmanjšanje nitratov, medtem ko se je v vzorcih mešane kulture alg vsebnost fosfatov zmanjšala le za 14 %, vsebnost nitratov pa se je celo povečala. Razlog je lahko bil slabo stanje mešane kulture alg in neustrezna izbira vrst alg</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-HCFJXAHB"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-HCFJXAHB" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-HCFJXAHB/ee9cf3e5-870e-4fc0-8c4b-7b2257f5652b/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc-sa/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-HCFJXAHB/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-HCFJXAHB" /></ore:Aggregation></rdf:RDF>
