Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Rapporten presenterer estimater for framtidig tilgjengelig kvantum av GROT (greiner og topper) fra sluttavvirkning i Innlandet, basert på avvirkningsstatistikk fra Statistisk sentralbyrå og Landsskogtakseringens registreringer i fylket i perioden 2016-2020. Rapporten er utarbeidet på oppdrag fra Stasforvalteren i Innlandet.

The demand for meat products is rising globally. A potential substitute for meat is synthetic meat, meat produce d in the laboratory. Synthetic meat is not in the market yet due to high production costs and regulatory issues, but it will probably be available during the next decade. If cheap and popular it may crowd out the demand and production of farmed meat and herby affect farmers income. In this study we have used data from a choice experiment in Norway to construct price and income elasticities for synthetic meat with three different assumptions. The data shows that half of the population does not accept synthetic meat. They will not buy it whatever the price. The own-price elasticities were estimated to be in the interval [-0.47,-0.08] and the cross-price elasticities were in the interval [0.09,0.40]. The income elasticities were all close to 0. If these elasticities were valid in a situation in which synthetic meat is available on the market, we could infer that the market for synthetic meat is limited.

Fish waste (FW) contains large amounts of protein and is a challenging feedstock for biogas production due to possible H₂S and ammonia generation. Adding FeCl3 to an anaerobic digester can precipitate H₂S. Mackinawite and greigite are conductive and magnetic substances formed from H₂S precipitation. Direct interspecies electron transfer (DIET) can be stimulated by developing these conductive materials and by applying an external magnetic force. In this study, FW was digested in batch reactors and exposed to magnets magnetic fields from 3 to 115 mT. The results showed that the use of magnetic fields could increase the biomethane yield by up to 36 %. XRD analyses showed that mackinawite and greigite were accumulating in the solid phase in digesters added FeCl3. Genetic analysis of the microbial community suggested that applying a magnetic field not only increased the relative abundance of protein-hydrolyzing bacteria but also potentially improved methane production through DIET.
