ABSTRACT The use of microalgal starch has been studied in biorefinery frameworks to produce bioethanol or bioplastics, however, these products are currently not economically viable. Using starch−rich biomass as an ingredient in food applications is a novel way to create more value while expanding the product portfolio of the microalgal industry. Optimization of starch production in the food−approved species Chlorella vulgaris was the main objective of this study. High−throughput screening of biomass composition in response to multiple stressors was performed with FTIR spectroscopy and nitrogen starvation was identified as an important factor for starch accumulation. Further studies were subsequently performed to assess the role of light distribution, investigating photon supply rates in flat panel photobioreactors. Biomass specific photon supply rate proved to have a strong effect on the accumulation of storage compounds and starch−rich biomass with up to 30% starch was achieved in cultures with low inoculation density (0.1 g L−1) and high irradiation (1800 μmol m−2 s−1). A final large scale experiment was performed in 25 L tubular reactors, achieving a maximum of 44% starch in the biomass after 12 hours in nitrogen starved conditions. Keywords: Chlorella vulgaris, starch, FTIR, photon supply rate, microalgae

The knowledge- and technology platform developed within the ALGAE TO FUTURE project aims to lay a foundation for an industrial microalgae production in Norway. In the project ALGAE TO FUTURE, funded by the Norwegian Research Council 2017-2021, with a consortium of 20 national and international research and industry partners, research and product development of microalgae biomass have been approached from multiple angles merging multiple research fields. The focus of the research has been bioprocess developments linked to lipids, carbohydrates and proteins, where species selection and cultivation conditions are used to obtain microalgae biomass with specific nutrient composition targeting specific products. We have chosen to target the development of three example products, namely 1) bread using algae biomass with high protein content, 2) beer using algae biomass with high content of starch and starch-degrading enzymes, and 3) fish feed using algae biomass with high PUFA content. These case studies have been chosen in order to demonstrate the use of algal biomass from various algae species with highly different nutrient composition suitable for different products. We have in this project studied the whole process line from small scale microalgae cultivation technology, upscaling cultivation, processing of algae biomass, shelf life, food/ feed product development, food safety and consumers attitudes. Some highlights from the four-year project period will be presented. Results from these activities may contribute towards the use of microalgae as part of the future Norwegian bioeconomy.

Mattilsynet har i samarbeid med NIBIO undersøkt nivåene av visse naturlige giftstoffer (plantetoksiner) for å få mer data og kunnskap om nivåene i utvalgte matvarer. Dette gjelder plantetoksinene tropane alkaloider i kornbasert mat og urtete, og pyrrolizidin alkaloider i te og urtete. I 2019 fant vi tropane alkaloider i form av atropin i 2 av 10 frokostblandinger og atropin og skopolamin i 1 av 5 urtete. Funnet var over den foreslåtte grenseverdien for tropane alkaloider i urtete. Det ble påvist pyrrolizidin alkaloider i 9 av 15 prøver av te og urtete. En av urteteene (merket ammete) hadde nivåer over den grenseverdien som nylig ble fastsatt for pyrrolizidin alkaloider i urtete i 2021. I 2020 ble det påvist tropane alkaloider i form av skopolamin i 2 av 5 prøver maismel, og pyrrolizidin alkaloider ble påvist i 18 av 25 prøver av urtete. Ingen av prøvene hadde nivåer over den foreslåtte grenseverdien for tropane alkaloider i maismel eller over grenseverdien som nylig ble fastsatt for pyrrolizidin alkaloider i urtete i 2021. Der det er gitt grenseverdier for disse giftstoffene i mat vil resultatene bli fulgt opp overfor selger av produktene og inngå i den offentlige kontrollen av reguleringen på matområdet. Der det ikke er gitt grenseverdier, vil resultatene bidra inn i kunnskapsgrunnlaget for vurdering av ny regulering av disse giftstoffene i mat.

In March 2021, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by four families (Aliusviridae, Crepuscuviridae, Myriaviridae, and Natareviridae), three subfamilies (Alpharhabdovirinae, Betarhabdovirinae, and Gammarhabdovirinae), 42 genera, and 200 species. Thirty-nine species were renamed and/or moved and seven species were abolished. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.
