1. 16. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy

   Författare :Ronny Purwadi; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMF; serial bioreactor; immobilization; overliming; furfural; ethanol; continuous cultivation; S. cerevisiae; flocculating yeast; continuous detoxification; dilute-acid hydrolyzate;

   Sammanfattning : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. LÄS MER

3. 17. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

   Författare :Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

   Sammanfattning : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. LÄS MER

4. 18. Methane and Volatile Fatty Acids Production from Toxic Substrate

   Författare :- Lukitawesa; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

   Sammanfattning : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. LÄS MER

5. 19. Interaction Analysis in Multivariable Control Systems : Applications to Bioreactors for Nitrogen Removal

   Författare :Björn Halvarsson; Bengt Carlsson; Elling Jacobsen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; biological nitrogen removal; bioreactor models; control structure design; cost-efficient operation; decentralized control; interaction measures; minimum variance control; multivariable control; wastewater treatment; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Many control systems of practical importance are multivariable. In such systems, each manipulated variable (input signal) may affect several controlled variables (output signals) causing interaction between the input/output loops. LÄS MER

7. 20. Fermentative hydrogen and methane productions using membrane bioreactors

   Författare :Julius Akinbomi; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

   Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.
