Continuous fermentation and kinetic experiments for the Conversion of crude glycerol derived from second-generation biodiesel into 1,3 propanediol and butyric acid

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1504371

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 non-sterile conditions. Eight different continuous flow stirred-tank reactors (CST...

L-lysine production by Bacillus methanolicus: Genome-based mutational analysis and L-lysine secretion engineering

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1458766

Bacillus methanolicus is a methylotrophic bacterium with an increasing interest in academic research and for biotechnological applications. This bacterium was previously applied for methanol-based production of l-glutamate, l-lysine and the five-carbon diamine cadaverine by wild type, classical muta...

6-Phosphofructokinase and ribulose-5-phosphate 3-epimerase in methylotrophic Bacillus methanolicus ribulose monophosphate cycle

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1458765

...d-Ribulose-5-phosphate-3-epimerase (RPE) and 6-phosphofructokinase (PFK) catalyse two reactions in the ribulose monophosphate (RuMP) cycle in Bacillus methanolicus. The B. methanolicus wild-type strain MGA3 possesses two putative rpe and pfk genes encoded on plasmid pBM19 (rpe1-MGA3 and pfk1-MGA3) a...

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

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1415217

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 and a putative mannitol activator gene mtlR were identified. The mannitol induc...

Draft genome sequence of the docosahexaenoic acid producing thraustochytrid Aurantiochytrium sp. T66

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1355038

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 high levels of docosahexaenoic acid (DHA). Here, we report the draft genome seque...

Thraustochytrids as production organisms for docosahexaenoic acid (DHA), squalene, and carotenoids

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1354976

Thraustochytrids have been applied for industrial production of the omega-3 fatty acid docosahexaenoic (DHA) since the 1990s. During more than 20 years of research on this group of marine, heterotrophic microorganisms, considerable increases in DHA productivities have been obtained by process and me...
