  2. 1. Biotransformations of Turpentine Constituents : Oxygenation and Esterification

    Author : Marica Lindmark-Henriksson; KTH; []
    Keywords : Picea abies; Pinaceae; Essential oils composition; Terpene alcohol; Hemiacetal; Hemiacetal ester; TMP-turpentine; Monoterpene; alpha-pinene; beta-pinene; Limonene; Verbenol; Pinocarveol; Borneol; Myrtenol; Suspension cell culture; Biotransformation; ;

    Abstract : This thesis describes methods to obtain value–addedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. READ MORE

  4. 2. Heterogeneously Catalyzed Valorization of Monoterpenes to High Value-Added Chemicals

    Author : Mikhail Golets; Jyri-Pekka Mikkola; Evgenii Rebrov; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalysis; terpenes; alpha-pinene;

    Abstract : A potential industrial process is profitable only if it is successfully implemented by the continuously developing chemical industry. Throughout last decades heterogeneous catalysis has opened doors to the creation of various know-how products which previously were considered unfeasible. READ MORE

  5. 3. Biochemical Interactions of Some Saproxylic Fungi

    Author : Joel Ljunggren; Bengt Gunnar Jonsson; Erik Hedenström; Dan Bylund; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biologically active compounds; bioactive; fungi-fungi interaction; fungi co-culture; extracellular amino acids.;

    Abstract : Interactions are all around us, and as humans we may use words and gestures to communicate our intentions. At the micro level of fungi, communications are replaced by chemical signals and structure. READ MORE

  6. 4. Some Approaches to Eco-Friendly Products from Natural Matrices

    Author : Joel Ljunggren; Erik Hedenström; Olav Martin Kvalheim; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Since the onset of the industrial and chemical revolution, humans have caused immense damages to the surrounding flora and fauna. Effective methods for wood protection measures proved to be toxic; fossil fuels contribute to global warming and pesticides can be detected in the air, water, and soil. READ MORE

  7. 5. Terpenes Emitted to Air from Forestry and the Forest Industry

    Author : Ann-Margret Hvitt Strömvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; thermal desorption; anthropogenic terpene emissions; softwood; hydrocarbon emission; environment; phytotoxic photooxidants; adsorption sampling;

    Abstract : A major environmental concern with respect to hydrocarbon emissions is the formation of phytotoxic photooxidants. The work reported in this thesis focusses on the poorly studied anthropogenic terpene emissions from the industrial use of softwood. READ MORE
