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

http://www.sintef.no/en/publications/publication/?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

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...

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

http://www.sintef.no/en/publications/publication/?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...

High production of recombinant Norwegian salmonid alphavirus E1 and E2 proteins in Escherichia coli by fusion to secretion signal sequences and removal of hydrophobic domains

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1059366

The Norwegian salmonid alphavirus (NSAV) infects farmed Atlantic salmon and rainbow trout, causes pancreas disease and leads to economic losses and fish health issues for the aquaculture. Vaccines are available, but recurring infection outbreaks at Norwegian fish farms have led to endeavours in find...

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

http://www.sintef.no/en/publications/publication/?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...

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

http://www.sintef.no/en/publications/publication/?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...

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

http://www.sintef.no/en/publications/publication/?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...
