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.

I St.meld. nr. 39 "Klimautfordringene - landbruket en del av Løsningen" heter det at det er et realistisk mål å redusere utslippene av klimagasser i Norge innen 2020 med 15 - 17 millioner tonn C02-ekvivalenter. Herav skal tiltak knyttet til behandling av husdyrgjødsel og matavfall i biogassanlegg alene stå for 0,5 millioner tonn. Rapporten omhandler klimagevinst og kostnader ved anaerob behandling av husdyrgjødsel eventuelt i kombinasjon med våtorganisk avfall frem mot 2020 og 2030. Det fremgår at enkelte av grunnlagsdataene som er benyttet foreløpig er heftet med stor grad av usikkerhet og at også forhold knyttet til teknologi og økonomi forventes å endre seg i tiltaksperioden.

The fruit quality of European blueberry (EB) is mainly determined by taste compounds (sugars, acids, flavour) and health-beneficial structures generally denoted as antioxidants (vitamin C, phenolic acids, flavonols, anthocyanins, proanthocyanidins). Content and compound composition is strongly affected by the growth environment regarding light, temperature, water and edaphic factors. In order to assess genotypic relationships (northern and southern clones of EB) and environmental impact (temperature, day length) on berry quality parameters, a high-throughput system for blueberry metabolite profiling of nutritional compounds was established based on gas chromatography coupled with mass spectrometry (GC/MS). Dried methanol/H2O extracts from fresh-frozen berry tissue were derivatized, and subjected to GC/MS in order to detect polar compounds such as organic acids from Krebs-cycle, amino acids, sugars, polyols, and partly secondary metabolites (phenols, flavonoids). In addition, general quality parameters such as total phenols, total anthocyanins and antioxidant capacity (FRAP) were measured. Fructose (5 g), glucose (5 g), and sucrose (0.5 g/ 100 g f.w. at average) were the most abundant carbohydrates, together with high levels of organic acids such as citric acid (1.3 g), quinic acid (1.6 g), and malic acid (0.3 g/ 100 g f.w. at average). More than 50 metabolites per sample (identified compounds and not-annotated mass spectral tags) could be detected, and established the basis for multivariate statistics using principal component analysis, hierarchical clustering, and metabolite network analysis. Genotypic differences, modulation of metabolite pools and biosynthetic relationships are being discussed in-depth.

The halogens, most importantly fluorine, chlorine, bromine, and iodine, occur in nature as ions and compounds, including organic compounds. Halogenated organic substances (haloorganics) were long considered purely anthropogenic products; however, they are in addition a commonly occurring and important part of natural ecosystems. Natural haloorganics are produced largely by living organisms, although abiotic production occurs as well. A survey is given of processes of formation, transport, and degradation of haloorganics in temperate and boreal forests, predominantly in Europe. More work is necessary in order to understand the environmental impact of haloorganics in temperate and boreal forest soils. This includes both further research, especially to understand the key processes of formation and degradation of halogenated compounds, and monitoring of the substances in question in forest ecosystems. It is also important to understand the effect of various forest management techniques on haloorganics, as management can be used to produce desired effects.
