3. 2. Physiology of Caulobacter crescentus grown on different carbon sources

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Sara Lind Jónsdóttir Glaser; [2016]
   Nyckelord :aerobic cultivation; physical characterization; lignocellulosic biomass; xylose degradation; Weimberg; bioreactors; enzyme assays; chemical engineering; kemiteknik; Technology and Engineering;

   Sammanfattning : Freshwater, obligate aerobic, Gram-negative bacterium Caulobacter crescentus strain CB2 is able to metabolise various types of carbon sources. In this degree project, growth characterization of C.crescentus was made on different substrates including glucose, xylose, and mannose using shake-flask cultivations and bioreactor experiments.

4. 3. Combined production of bioethanol and biogas from wheat straw

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Victor Gustafson; [2015]
   Nyckelord :lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

   Sammanfattning : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. LÄS MER

5. 4. Enzymatisk nedbrytning av arabinoxylan och fytinsyra som metod för att öka utbytet och biotillgängligheten av näringsämnen i flytande havrebas

   Master-uppsats, Lunds universitet/Bioteknik

   Författare :Anna Aronsson; Sara Strandberg; [2013]
   Nyckelord :Phytic acid; Arabinoxylan; Phytate; Xylanase; Oat; Bioavailability; Technology and Engineering;

   Sammanfattning : This project (Enzymatic degradation of arabinoxylan and phytic acid as a method to increase yield and bioavailability of nutrients in liquid oat base) evaluates the degradation of phytic acid, of the insoluble fraction from Oatly’s existing production process, with the aim of increasing available nutrients such as minerals and proteins. Previous studies have shown that phytic acid from this fraction is hard to disassemble and one possible theory is that the phytic acid is tightly bound to the fibers and hence hard to access.
