Netto utslipp av karbon til atmosfæren har økt siden starten på den industrielle revolusjon. Rundt halvparten av karbon som slippes ut blir tatt opp av havet fysisk via karbon fluks eller bundet opp i økosystemer i havet eller på land. Denne oppgaven tolker og diskuterer potensielle lokale virkninger av industriell CO2 utslipp ved å benytte fysiske og biologiske, oseanografi og CO2 data samlet ...

Fungi are among the most prolific producers of secondary metabolites, many of which have huge utility for society as various anti-infective and anticancer drugs. The genes encoding these secondary metabolites are arranged in continuous biosynthetic gene clusters (BGCs). Each fungus can have tens of different BGCs in its genome, possessing the ability to produce a multitude of secondary metabolites ...

Global trends show that interest in fish products and fish consumption are increasing, while marine fishery resources are decreasing. Fish processing industry produces a high amount of residual raw materials that have nutritious proteins and other valuable compounds. An optimization of residual raw materials’ utilization can help meet the growing demand for fish products and help reduce environmental ...

The fast growth of the aquaculture sector has led to an unsustainable harvest of wild fish species used in the production of aquaculture feed. Integrated Multi-trophic Aquaculture (IMTA) promises ecological and socio-economic advantages that include the provision of sustainable aquaculture feed. However, the promotion of IMTA requires that the stakeholders have sufficient quantitative information ...

Metabolic syndrome (MetS) is the medical term for a cluster of risk factors including obesity, high blood pressure, and high blood sugar, which increases the risk of developing stroke, heart disease, and type 2 diabetes. Marine raw materials have been described to exert various bioactive properties beneficial to human health, including anti-inflammatory, antioxidant, and antidiabetic abilities. In ...

Pollution of plastic in itself has become a growing focus in the last 15 years. In addition, the impact of plastic as a reservoir for pathogenic bacteria and transfer of antibiotic resistance genes has become a global concern, for individuals, organizations, policymakers and health organizations. It is important to document the relationship of microbiota associated to different types of plastic ...

Marine environments contain half of the global biodiversity and are a major source of bioactive compounds. Macroalgae are vital species in marine ecosystems and are known to produce several bioactive compounds and polysaccharides that possesses several bioactivities. These molecules are traditionally extracted using methods that heavily rely on hazardous solvents and heat, that more importantly ...

Microalgae are grown in different habitats and conditions, such as high salinity, extreme temperatures, and variable pH. Cold-adapted microalgae may have the capacity of generating high biomass production, which can potentially be produced under cold and light-limited conditions in the Arctic. Most microalgae are obligated photoautotrophs; however, few species have been found living in complete ...

Cold-adapted enzymes are of biotechnological value due to their high catalytic powers at low to moderate temperatures and their high thermolability at elevated temperatures. Marine fungi are an understudied group of organisms, which makes them interesting as enzyme producers because of their adaptions to marine habitats. In this thesis study, a bioprospecting pipeline was constructed, and different ...

Micro- and nanoplastic particles, produced from the breakdown of larger plastic debris, represent a whole new field of hazardous pollution with the potential to cause great damage on a range of marine species. This escalating concern of plastic pollution in marine environments and its consequential impacts on marine species, has emphasized the urgency for an in-depth understanding of the uptake and ...
