Abstract
Biogas is a product produced by anaerobic digestion, where different microorganisms break down organic matter through different metabolic pathways. Biogas has a large potential source of energy, and biogas production technology is favorable due to environmental protection and reduction of greenhouse gases. In the Republic of Croatia, there is only one factory that grows Chlorella (PHYOX D.O.O.). With a high dry matter content, Chlorella is a potentially good source of substrate for biogas production. Bovine slurry as a control substrate has a low concentration of dry matter, i.e. 3.02% dry matter. The average dry matter of Chlorella is 94.22%. The proportion of volatile and organic matter is within high limits, which is important for biogas production. In all groups, the dynamics of production was monitored over a period of 21 days. The control group produced an average value of 3666.67 ml of biogas. The control group was surpassed by the experimental groups where the average value ranges from 5160 to 7600 ml of biogas. The highest production of methane per gram of dry organic matter (mlCH 4 /gOT) in the amount of 1000 ml was achieved by the experimental group of cattle manure with 10g of dry algae.
Abstract (croatian)
Bioplin je proizvod proizveden anaerobnom digestijom, gdje različiti mikroorganizmi razgrađuju organsku tvar različitim metaboličkim putovima. Bioplin ima veliki potencijalni ka izvor energije, a tehnologija proizvodnje bioplina je povoljna zbog zaštite okoliša i smanjenja stakleničkih plinova. U Republici Hrvatskoj postoji samo jedna tvornica koja se bavi uzgojem klorele (PHYOX D.O.O.). S visokim sadržajem suhe tvari Chlorella je potencijalno dobar izvor supstrata za proizvodnju bioplina. Goveđa gnojnica kao kontrolni supstrat ima nisku koncentraciju suhe tvari, tj. 3,02% suhe tvari. Prosječna suha tvar Chlorella je 94,22%. Udio hlapljivih i organskih tvari je u visokim granicama, što je važno za proizvodnju bioplina. U svim skupinama praćena je dinamika proizvodnje u razdoblju od 21 dan. Kontrolna skupina proizvela je prosječnu vrijednost od 3666,67 ml bioplina. Kontrolnu skupinu nadmašile su eksperimentalne skupine gdje se prosječna vrijednost kreće od 5160 do 7600 ml bioplina. Najveću produkciju metana po gramu suhe organske tvari (mlCH 4 /gOT) u količini od 1000 ml postigla je pokusna skupina goveđeg gnoja s 10 g suhe alge.
