21. 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
22. An Alkaline Active Endo-Xylanase from Bacillus halodurans S7:Molecular and Structural Aspects
Sammanfattning : A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. LÄS MER
23. Integration of filamentous fungi in ethanol dry-mill biorefinery
Sammanfattning : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. LÄS MER
24. Thermostable glycosidases and glycosynthases as biocatalysts in green chemistry applications
Sammanfattning : The constant need to develop environmental friendly processes using renewable raw materials and to reduce harmful waste production motivates the present investigation focusing on biocatalyst development for enzymatic synthesis, a biotechnological approach in the field of green chemistry. At first, structural functional experiments were made for a β-glucosidase from T. LÄS MER
