  1. 1. 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.

    Abstract : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). READ MORE

  3. 3. Characterization of microbial growth in lignin-based residues and biodegradation of vanillin: : Optimizing factors for maximizing the extraction of a biodegradation compound of vanillin and investigating the potential for lipid accumulation.

    University essay from Högskolan i Gävle/Miljöteknik

    Author : Oscar Rosales; [2017]
    Keywords : Yeast; vanillin biodegradation; vanillyl alcohol; lignin-based substrates; microbial lipid accumulation; Thin-layer chromatography;

    Abstract : Vanillin (4-hydroxy-3methoxybenzaldehyde) is one of the most employed aromatic and flavoring additives in food and cosmetic industry. The industrial interest in vanillin could also apply to its biodegradation products. READ MORE

  4. 4. Growth and biodegradation by Sporidiobolales yeasts in vanillin-supplemented medium

    University essay from Högskolan i Gävle/Avdelningen för arbets- och folkhälsovetenskap

    Author : Natalia González Gaarslev; [2017]
    Keywords : Sporobolomyces; Vanillin; Internal Transcribed Spacer ITS ; Thin layer chromatography TLC ; Neubauer’s chamber; Sporobolomyces; Vainillina; Espaciador Transcribible Interno ETI ; Cromatografia en capa fina CCF ; Cámara de Neubauer;

    Abstract : Studies of biodegradation in lignins by basidiomycetes yeasts show the conversion of lignin in various degradation products among which vanillin, a valuable substance, suggested to be a strong inhibitor of both fermentation and growth of yeasts, stands. Sporidiobolales yeasts used in these experiments were aimed to be identified by their highly conserved ITS region as well as studied in vanillinsupplemented medium through, vanillin-supplemented plates, TLC and Neubauer’s chamber to find out which, among the several isolates tested, were the most resistant ones, understand how they take up vanillin and how their growth is affected by the presence of the phenolic compound.

  5. 5. Methane Oxidation in three Swedish Forest Soils

    University essay from SLU/Dept. of Soil and Environment

    Author : Kwesi Idun Osam; [2012]
    Keywords : methane; oxidation; forest; soils; methanotrophs; multi-carbon compounds; consumption;

    Abstract : Aerated soils are the largest sinks of atmospheric methane on the Earth’s surface. Methane removal from the atmosphere is performed through oxidation by microorganisms (methaneoxidising bacteria) in the soil. READ MORE
