Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. 3 ultrafiltration-membranes, RC70PP, GR70PP and ETNA10PP from Alfa Laval Corporate AB, were evaluated at varying cross-flow
Voting cohesion in the European Parliament is a thoroughly studied field, however a deep dive into the kingmaker of coalition building, the liberal party group, has yet to be done.

Varg har naturligt förekommit i hela landet genom historien men arten försvann nästan helt ur den svenska faunan under 1900-talet. Nu har vargen återigen etablerat sig i Sverige. Förutsättningarna för att förvalta varg genom jakt, så kallad licensjakt, är strikt begränsat. De bestämmelser som reglerar möjligheten till licensjakt på varg grundar sig på EU:s art- och habitatdirektiv, AHD. Dessa haWolves have occurred naturally across the country throughout history but disappeared almost completely from the Swedish fauna during the 20th century. Now the wolf has again established itself in Sweden. The prerequisites for managing wolves through hunting, known as licensed hunting, are strictly restricted. The provisions regulating the possibility to licensed hunting of wolves are based on the
There has been much debate about the Japanese management system and its changes as well as continuity. There is a consensus that the Japanese human resource management rests on three core pillars which are lifetime employment, seniority based salaries/promotions and unions. The purpose of this study was to investigate if these three core pillars have transformed after the 1990's when the eco
The Arctic tundra has been considered as one of the most sensitive areas to global climate change. One impact of global warming is that permafrost thawing could result in more waterlogged and anaerobic conditions, and consequently an increasing release of methane (CH4) to the atmosphere. These potential CH4 emissions can further amplify global warming. Therefore, it is important to assess the quan
Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF

The human gut contains a vast number of bacteria. These bacteria allow us to digest the complex glycans that are part of our diet but we ourselves cannot digest. Among these bacteria one of the genera that is a major constituent is Bacteroidetes. One of the distinguishing features of this genus is its polysaccharide utilizing loci (PULs), clusters of genes for degradation of specific glycans and e
