16. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia
Sammanfattning : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. LÄS MER
17. Snow and ice studies in Antarctica
Sammanfattning : .... LÄS MER
18. Protein Engineering of Candida antarctica Lipase A : Enhancing Enzyme Properties by Evolutionary and Semi-Rational Methods
Sammanfattning : Enzymes are gaining increasing importance as catalysts for selective transformations in organic synthetic chemistry. The engineering and design of enzymes is a developing, growing research field that is employed in biocatalysis. LÄS MER
19. Engineering Candida antarctica Lipase A for Enantioselective Transformations in Organic Synthesis : Design, Immobilization and Organic Solvent Screening of Smart Enzyme Libraries
Sammanfattning : The use of enzymes as catalysts in organic synthesis constitutes an attractive alternative to conventional chemical catalysis. Enzymes are non-toxic and biodegradable and they can operate under mild reaction conditions. LÄS MER
20. Exploring Conjugate Addition Activity in Pseudozyma antarctica Lipase B
Sammanfattning : Multifunctional enzymes have alternative functions or activities, known as “moonlighting” or “promiscuous”, which are often hidden behind a native enzyme activity and therefore only visible under special environmental conditions. In this thesis, the active-site of Pseudozyma (formerly Candida) antarctica lipase B was explored for a promiscuous conjugate addition activity. LÄS MER
