   Författare :Tarek Dishisha; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER

   Sammanfattning : AbstractTransition from fossil- to bio-based economy is a critical step towards reduction of greenhouse gas emissions and climate change, and hence for achievement of sustainable communities and environment. In order to be fossil-free, the chemical and material industry is in need of carbon-neutral building blocks from renewable resources for the diverse array of products that are currently produced from olefins and aromatics.

4. 3. Towards sustainable plastics : Microbial production of aromatic and aliphatic building blocks from biobased feedstock and plastic hydrolysate

   Författare :Oliver Englund Örn; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell factories; Biobased plastics; Protocatechuic acid; Adipic acid; 4-Hydroxybyratate; 1; 4-Butanediol; PBAT; Enzymatic recycling; Synthetic promoter library;

   Sammanfattning : The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material.
