1. Wild plants can improve their rhizosphere chemistry in acid soils
Sammanfattning : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. LÄS MER
2. Malic acid production by Aspergillus oryzae
Sammanfattning : Malic acid is a C4 dicarboxylic acid which is used as an acidulant in food and beverages. It isalso considered as a bio-building block to replace petrochemically derived compounds in thepost oil era. This organic acid can be biotechnologically derived from fermentation usingrenewable feedstocks as carbon source. LÄS MER
3. Atmospheric Change and Potato. The Impact of tropospheric ozone and elevated carbon dioxide on tuber yield and quality
Sammanfattning : .... LÄS MER
4. Synthesis and characterization of dendritic macromolecules based on 2,2-bis(hydroxymethyl)propionic acid
Sammanfattning : Dendrimers are a relatively new type of macromolecules characterized by a well-defined, highly branthed, layered structure with a multitude of chain ends, adopting a globular shape at higher molar masses. Dendrimers are usually constructed from ABx type of monomers in either one of the two step-wise approaches known as thedivergentor theconvergent growth approach. LÄS MER
5. Low Molecular Weight Organic Acids and Their Aluminium Complexes in Forest Soils
Sammanfattning : The significance of low molecular weight (LMW) organic acids and their aluminium (Al) complexes in soil solutions of podzolized soils was examined. Methods for the analysis of these compounds and complexes were developed, and the impact of these substances on the weathering and podzolization processes was studied. LÄS MER
