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.

«Bjørk i Norge» er sluttrapporten etter det treårige prosjekt «Flaskehalser og barrierer for økt bruk av bjørk» som er utført av en gruppe forskere ved NIBIO. Formålet med rapporten er å gi en oversikt over dagens bjørkeressurser, prognoser for volum og tilvekst samt dagens bruk av bjørk. Vi beskriver brukspotensiale, flaskehalser og barrierer for økt og kvalitetstilpasset bruk av bjørk og gjennomgår dagens kunnskap om foryngelse og skjøtsel av bjørk. I tillegg gir rapporten en oversikt over kvalitetsevalueringer av bjørk, samt en presentasjon av en studie om «forbedret kvalitetsevaluering av bjørkestokker». Vi påpeker fremtidige forskningsbehov og handlingsmuligheter for å få en bedre utnyttelse av avvirket virke, en mer kvalitetstilpasset bruk og en generell økt bruk av norsk bjørk.

Black soldier fly larvae (BSFL) Hermetia illucens is fastest growing and most promising insect species especially recommended to bring high-fat content as 5th generation bioenergy. The fat content can be fully optimized during the life-cycle of the BSFL through various organic dietary supplements and environmental conditions. Enriched fat can be obtained during the larval stages of the BSF. The presence of high saturated and unsaturated fatty acids in their body helps to produce 70 % of extractable oil which can be converted into biodiesel through transesterification. The first-generation biodiesel process mainly depends on catalytic transesterification, however, BSFL had 94 % of biodiesel production through non-catalytic transesterification. This increases the sustainability of producing biodiesel with less energy input in the process line. Other carbon emitting factors involved in the rearing of BSFL are less than the other biodiesel feedstocks including microalgae, cooking oil, and non-edible oil. Therefore, this review is focused on evaluating the optimum dietary source to produce fatty acid rich larvae and larval growth to accumulate C16–18 fatty acids in larger amounts from agro food waste. The process of optimization and biorefining of lipids using novel techniques have been discussed herein. The sustainability impact was evaluated from the cultivation to biodiesel conversion with greenhouse gas emissions scores in the entire life-cycle of process flow. The state-of-the-art in connecting circular bioeconomy loop in the search for bioenergy was meticulously covered.

Vaccinium berries include several economically important cultivated and wild species such as blueberries, cranberries, bilberries and lingonberries. These species are recognized for the various health beneficial properties, which are generally linked to the high yields and the complex profile of flavonoids in the berries, including anthocyanin, proanthocyanidin, and flavonol classes of flavonoids. Anthocyanins are one of the main pigments in plants contributing to the characteristic reddish to bluish colours in flowers and fruits. Most important anthocyanins are glucosides of six common aglycons: cyanidins, delphinidins, pelargonidins, petunidins, peonidins and malvidins. Of these, delphinidin branch anthocyanins, namely delphinidins, petunidins, and malvidins are responsible of bluish colours in blue Vaccinium berries. The biosynthesis of anthocyanins has been intensively studied, and the structural enzyme genes responsible of the specific steps of the pathway have been characterised also in diverse Vaccinium species. For the delphinidin branch, flavanone 3’5’ hydroxylase (F3’5’H) is the key enzyme for the branching point towards bluish anthocyanins. Our recent results both from controlled and field experiments have revealed new information on the key regulators controlling the different branches of the anthocyanin biosynthesis in blue-coloured berries. Transcriptome analyses combined with metabolite results have identified signaling routes leading to increase in delphinidin branch anthocyanins. Our results show that the anthocyanin composition in blue Vaccinium berries could be modified by specific environmental factors.
