Identification of genes affecting alginate biosynthesis in Pseudomonas fluorescens by screening a transposon insertion library

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1422769

BACKGROUND: Polysaccharides often are necessary components of bacterial biofilms and capsules. Production of these biopolymers constitutes a drain on key components in the central carbon metabolism, but so far little is known concerning if and how the cells divide their resources between cell growth...

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

https://www.sintef.no/publikasjoner/publikasjon/?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...

Anti-microbial and cytotoxic 1,6-dihydroxyphenazine-5,10-dioxide (iodinin) produced by Streptosporangium sp. DSM 45942 isolated from the fjord sediment

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1061610

Phenazine natural products/compounds possess a range of biological activities, including anti-microbial and cytotoxic, making them valuable starting materials for drug development in several therapeutic areas. These compounds are biosynthesized almost exclusively by eubacteria of both terrestrial an...

Combinatorial Mutagenesis and Selection of Improved Signal Sequences and Their Application for High-Level Production of Translocated Heterologous Proteins in Escherichia coli

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+961326

Continuous hydrogen production by sorption enhanced steam methane reforming (SE-SMR) has been studied using a circulating fluidized bed reactor with calcined natural dolomite as CO2 sorbent and Ni/NiAl2O4 as catalyst. A steam to methane ratio of 4 was used at 575 °C and ambient pressure. Two experim...

Investigating alginate production and carbon utilization in Pseudomonas fluorescens SBW25 using mass spectrometry-based metabolic profiling

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+965247

Metabolic profiling of Pseudomonas fluorescens SBW25 and various mutants derived thereof was performed to explore how the bacterium adapt to changes in carbon source and upon induction of alginate synthesis. The experiments were performed at steady-state conditions in nitrogen-limited chemostats usi...

Mapping global effects of the anti-sigma factor MucA in Pseudomonas fluorescens SBW25 through genome-scale metabolic modeling

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1027218

Alginate is an industrially important polysaccharide, currently produced commercially by harvesting of marine brown sea-weeds. The polymer is also synthesized as an exo-polysaccharide by bacteria belonging to the genera Pseudomonas and Azotobacter, and these organisms may represent an alternative al...

Functional Characterization of Key Enzymes involved in L-Glutamate Synthesis and Degradation in the Thermotolerant and Methylotrophic Bacterium Bacillus methanolicus

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1038717

Bacillus methanolicus wild-type strain MGA3 secretes 59 g/liter−1 of l-glutamate in fed-batch methanol cultivations at 50°C. We recently sequenced the MGA3 genome, and we here characterize key enzymes involved in l-glutamate synthesis and degradation. One glutamate dehydrogenase (GDH) that is encode...

Methylotrophic Bacillus methanolicus encodes two chromosomal and one plasmid born NAD+ dependent methanol dehydrogenase paralogs with different catalytic and biochemical properties

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1020618

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 the B. methanolicus strains MGA3 (ATCC53907) and PB1 (NCIMB13113) were sequenc...

Mannuronan C-5 Epimerases Suited for Tailoring of Specific Alginate Structures Obtained by High-Throughput Screening of an Epimerase Mutant Library

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1044305

The polysaccharide alginate is produced by brown algae and some bacteria and is composed of the two monomers, β-d-mannuronic acid (M) and α-l-guluronic acid (G). The distribution and composition of M/G are important for the chemical-physical properties of alginate and result from the activity of a f...
