  1. 1. Microbial production of chemical building blocks from lignin

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Kevin Bertilsson; [2024]
    Keywords : Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

    Abstract : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. READ MORE

  2. 2. Accelerating Techniques for Whisky Maturation : Effect of heat, iron and light on the maturation process

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Cihao Chen; [2022]
    Keywords : Food technology; whisky; oak; phenolic compounds; HPLC-DAD; Technology and Engineering;

    Abstract : The maturation of whisky is a long and complex process, the extremely long waiting time causes a large cost for new whisky distilleries, and without sufficient funding, it is hard to start a whisky business. To produce satisfying whisky products within the short term, accelerating the reaction during aging provides a promising approach. READ MORE

  3. 3. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE

  4. 4. Development and Validation of an Analytical Method for Phenolic Acid Extraction from Cereals and Quantification using HPLC-UV

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Laura Amann; [2018]
    Keywords : Phenolic acids; cereals; extraction; HPLC-UV analysis;

    Abstract : Cereals are rich in phenolic acids, a group of secondary plant metabolites that are associated with reduced risk of chronic diseases. The objective was to develop and internally validate a method for extraction and quantification of phenolic acids in cereals using HPLC-UV and to apply this method for quantification of the content of phenolic acids in several species of Swedish cereals.
