11. Heterobasidion - conifer pathosystem : heterologous array analysis and transcriptional shift from saprotrophic to necrotrophic growth
Sammanfattning : In this thesis the Heterobasidion – conifer pathosystem is discussed in a symbiosis context. Heterobasidion annosum (Fr.)Bref. s. LÄS MER
12. X-ray structure and function studies of key enzymes for biomass conversion: GH6 cellobiohydrolases and GH61 lytic polysaccharide monooxygenases (LPMO)
Sammanfattning : The need for large enzyme quantities due to the difficult hydrolysis of recalcitrant polysaccharides is still a major barrier to economical biomass conversion for biofuel production. To discover or develop new efficient wood degrading enzymes and add into enzyme cocktails are essential for optimizing enzymatic conversion of biomass. LÄS MER
13. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase
Sammanfattning : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

14. Chiral recognition on cellulases : The active sites of the enzymes are involved
Sammanfattning : Two cellobiohydrolases (CBH I and CBH II) and endoglucanase I (EG I) fromTrichoderma reesei, and CBH 58 from Phanerochaete chrysosporium were immobilized onsilica as chiral stationary phases (CSPs) in HPLC for enantioseparation of a group ofpharmaceutical compounds. CBH I and CBH 58 wore excellent chiral selectors for β-adrenergic blocking agents, whereas CBH II displayed good enantioselectivity for someother compounds The CBHs share the common feature that their active sites are located intunnels.

15. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose
Sammanfattning : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. LÄS MER
