Characterization of Microbial Diversity in Decayed Wood from a Spanish Forest: An Environmental Source of Industrially Relevant Microorganisms
Velasco-Rodríguez, Óscar; Fil, Mariana; Heggeset, Tonje Marita Bjerkan; Degnes, Kristin Fløgstad; Becerro-Recio, David; Kolsaková, Katarina; Haugen, Tone; Jønsson, Malene; Toral-Martínez, Macarena; García-Estrada, Carlos; Sola-Landa, Alberto; Josefsen, Kjell Domaas; Sletta, Håvard; Barreiro, Carlos (Peer reviewed; Journal article, 2022)Rotting wood is inhabited by a large diversity of bacteria, fungi, and insects with complex environmental relationships. The aim of this work was to study the composition of the microbiota (bacteria and fungi) in decaying ... -
Continuous fermentation and kinetic experiments for the Conversion of crude glycerol derived from second-generation biodiesel into 1,3 propanediol and butyric acid
Varrone, Cristiano; Floriotis, Georgis; Heggeset, Tonje Marita Bjerkan; Le, Simone Balzer; Markussen, Sidsel; Skiadas, Ioannis; Gavala, Hariklia N. (Journal article; Peer reviewed, 2017)This study investigated the performance of different mixed microbial cultures (MMC) able to ferment crude glycerol generated from animal fat-based biodiesel to produce 1,3 propanediol (1,3 PDO) and butyric acid, under ... -
Corrigendum: Genome-Based Genetic Tool Development for Bacillus methanolicus: Theta- and Rolling Circle-Replicating Plasmids for Inducible Gene Expression and Application to Methanol-Based Cadaverine Production
Irla, Marta Katarzyna; Heggeset, Tonje Marita Bjerkan; Nærdal, Ingemar; Paul, Lidia; Haugen, Tone; Le, Simone Balzer; Brautaset, Trygve; Wendisch, Volker F. (Journal article; Peer reviewed, 2019)Bacillus methanolicus is a thermophilic methylotroph able to overproduce amino acids from methanol, a substrate not used for human or animal nutrition. Based on our previous RNA-seq analysis a mannitol inducible promoter ... -
Draft genome sequence of the docosahexaenoic acid producing thraustochytrid Aurantiochytrium sp. T66
Liu, Bin; Ertesvåg, Helga; Aasen, Inga Marie; Vadstein, Olav; Brautaset, Trygve; Heggeset, Tonje Marita Bjerkan (Peer reviewed; Journal article, 2016)Thraustochytrids are unicellular, marine protists, and there is a growing industrial interest in these organisms, particularly because some species, including strains belonging to the genus Aurantiochytrium, accumulate ... -
Flow-based method for biofilm microbiota enrichment and exploration of metagenomes
Hageskal, Gunhild; Heggeset, Tonje Marita Bjerkan; Nguyen, Giang-Son; Haugen, Tone; Jønsson, Malene; Egas, Conceição; Hidalgo, Aurelio; Wentzel, Alexander; Lewin, Anna (Peer reviewed; Journal article, 2022)Most bacteria live in bioflms in their natural habitat rather than the planktonic cell stage that dominates during traditional laboratory cultivation and enrichment schemes. The present study describes the establishment ... -
Lipid and DHA-production in Aurantiochytrium sp. – Responses to nitrogen starvation and oxygen limitation revealed by analyses of production kinetics and global transcriptomes
Heggeset, Tonje Marita Bjerkan; Ertesvåg, Helga; Liu, Bin; Ellingsen, Trond Erling; Vadstein, Olav; Aasen, Inga Marie (Journal article; Peer reviewed, 2019)Thraustochytrids of the genera Schizochytrium and Aurantiochytrium accumulate oils rich in the essential, marine n3 fatty acid docosahexaenoic acid (DHA). DHA production in Aurantiochytrium sp T66 was studied with the aim ... -
Methylotrophic Bacillus methanolicus encodes two chromosomal and one plasmid born NAD+ dependent methanol dehydrogenase paralogs with different catalytic and biochemical properties
Krog, Anne; Heggeset, Tonje Marita Bjerkan; Müller, Jonas E.N.; Kupper, Christiane E.; Schneider, Olha; Vorholt, Julia A.; Ellingsen, Trond Erling; Brautaset, Trygve (Journal article, 2013)Bacillus methanolicus can utilize methanol as the sole carbon source for growth and it encodes an NAD+-dependent methanol dehydrogenase (Mdh), catalyzing the oxidation of methanol to formaldehyde. Recently, the genomes of ... -
Production of Value-Added Chemicals by Bacillus methanolicus Strains Cultivated on Mannitol and Extracts of Seaweed Saccharina latissima at 50C
Hakvåg, Sigrid; Nærdal, Ingemar; Heggeset, Tonje Marita Bjerkan; Kristiansen, Kåre Andre; Aasen, Inga Marie; Brautaset, Trygve (Peer reviewed; Journal article, 2020)The facultative methylotroph Bacillus methanolicus MGA3 has previously been genetically engineered to overproduce the amino acids L-lysine and L-glutamate and their derivatives cadaverine and γ-aminobutyric acid (GABA) ... -
A unified and simple medium for growing model methanogens
Ngoumelah, Daniel Dzofou; Harnisch, Falk; Sulheim, Snorre; Heggeset, Tonje Marita Bjerkan; Aune, Ingvild Haugnes; Wentzel, Alexander; Kretzschmar, Jörg (Peer reviewed; Journal article, 2023)Apart from their archetypic use in anaerobic digestion (AD) methanogenic archaea are targeted for a wide range of applications. Using different methanogenic archaea for one specific application requires the optimization ...
