5. 3. Production of L-arginine by Escherichia coli : Impact of genetic modifications, carbon and nitrogen sources

   Author : Mireille Ginesy; Ulrika Rova; Michael Sauer; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : In the recent years, the demand for environmental friendly produced L-arginine has risen with the increasing number of applications for this amino acid in pharmaceuticals, nutraceuticals, cosmetics, animal feed and fertilizers.Microbial production of L-arginine usually relies on Corynebacterium glutam-icum and Corynebacterium crenatum strains.

6. 4. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry

   Author : Katerina Hruzova; Ulrika Rova; Saija Luukkanen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organosolv lignin particles; Nanoparticles; Flotation reagent; Copper recovery; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. READ MORE

7. 5. Improved detection and performance of surface expression from the AIDA-I autotransporter

   Author : Johan Jarmander; Gen Larsson; Ulrika Rova; Ines Ezcurra; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface expression; autotransport; AIDA-I; Escherichia coli; proteolysis; detection tag;

   Abstract : Surface expression of recombinant proteins has attracted a lot of attention due to its potential in applications such as enzyme production, vaccine delivery and bioremediation. Autotransporters have been used for surface expression of a variety of proteins, but the expression systems reported in literature have typically been inflexible and incapable of detecting proteolysis, thereby limiting surface expression yield.
