Macromolecular acidic coating increases shelf life by inhibition of bacterial growth
(Journal article; Peer reviewed, 2018)The sensitivity of microorganisms to low pH can be utilized in food protection by preparing coatings based on macromolecular acids. Due to limited diffusivity of macromolecules low pH occurs primarily at the surface, while ... -
Major faecal microbiota shifts in composition and diversity with age in a geographically restricted cohort of mothers and their children
(Journal article; Peer reviewed, 2014)Despite the importance, the diversity of the human infant gut microbiota still remains poorly characterized at the regional scale. Here, we investigated the faecal microbiota diversity in a large 16S rRNA gene data set ... -
Management of biofloc concentrations as an ecological strategy for microbial control in intensive shrimp culture
(Peer reviewed; Journal article, 2021)This study investigated if the intensity of sedimentation through settling tanks modifies the bacterial community composition of biofloc systems and affects performance of shrimp. A 50-day trial, which was conducted with ... -
Managing the microbial community of marine fish larvae: a holistic perspective for larviculture
(Journal article; Peer reviewed, 2018)The availability of high-quality juveniles is a bottleneck in the farming of many marine fish species. Detrimental larvae-microbe interactions are a main reason for poor viability and quality in larval rearing. In this ... -
Manganese acquisition is facilitated by PilA in the cyanobacterium Synechocystis sp. PCC 6803
(Journal article; Peer reviewed, 2017)Manganese is an essential element required by cyanobacteria, as it is an essential part of the oxygen-evolving center of photosystem II. In the presence of atmospheric oxygen, manganese is present as manganese oxides, which ... -
Mannuronan C-5 Epimerases Suited for Tailoring of Specific Alginate Structures Obtained by High-Throughput Screening of an Epimerase Mutant Library
(Journal article; Peer reviewed, 2013)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 ... -
Mannuronate C-5 epimerases and their use in alginate modification
(Journal article; Peer reviewed, 2023)Alginate is a polysaccharide consisting of β-D-mannuronate (M) and α-L-guluronate (G) produced by brown algae and some bacterial species. Alginate has a wide range of industrial and pharmaceutical applications, owing mainly ... -
Mapping anaerobic sludge bed community adaptations to manure supernatant in biogas reactors
(Journal article; Peer reviewed, 2018)In upflow anaerobic sludge bed (UASB) reactors, biomass present as granules allows for long solids retention time. Here, granules from a process treating pulp and paper industrial wastewater were successfully applied as ... -
Mapping bacterial community structures in skin and gill mucus of Atlantic salmon (Salmo salar) smolt from four commercial RAS facilities
(Master thesis, 2021)Resirkulerende akvakultursystemer (RAS) har økt i popularitet for oppdrett av atlantisk laks (Salmo salar). I RAS blir fisken kontinuerlig utsatt for mikrober som lever i det resirkulerende vannet, der enkelte også har ... -
Mapping global effects of the anti-sigma factor MucA in Pseudomonas fluorescens SBW25 through genome-scale metabolic modeling
(Journal article; Peer reviewed, 2013)Background: 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 ... -
Marine biofouling - microbial adhesion to non-solid gel surfaces
(Dr. ingeniøravhandling, 0809-103X; 2001:114, Doctoral thesis, 2002)The scope for this work was to develop rapid assays for enumerating microorganisms on gels, and to test whether fouling of gel surfaces is principally different from that of solid substrata. For this purpose, a standard ... -
Marine Capture Fisheries from Western Indian Ocean: An Excellent Source of Proteins and Essential Amino Acids
(Peer reviewed; Journal article, 2023)The Republic of Seychelles is located in Western-Central Indian Ocean, and marine capture fisheries play a key role in the country’s economic and social life in terms of food security, employment, and cultural identity. ... -
Marine Cod (Gadus morhua) Head Hydrolysates - in vitro ACE inhibitory activity and investigation of structure-activity relationship
(Master thesis, 2018)Marine by-products contain valuable nutrients and there is an increasing interest in production of value-added products for human consumption. Cod (Gadus morhua) head hydrolysates produced by SINTEF Ocean in the pilot ... -
Marine Phospholipids: Methods to Measure Oxidation Status and Stability
(Master thesis, 2014)Marine phospholipids (MPL) have a higher content of the omega-3 fatty acids EPA and DHA than triacylglycerols from the same source. In addition they have been shown to have a better bioavailability, and a better resistance ... -
