1. Lignin-carbohydrate complexes: Model compounds synthesis
Sammanfattning : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.

2. Fundamental Aspects of Lignin Carbohydrate Complexes (LCC) : Mechanisms, Recalcitrance and Material concepts
Sammanfattning : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. LÄS MER
3. Enzyme assays for lignin–carbohydrate bond hydrolysis
Sammanfattning : To identify, produce, and use enzymes, analytical methods known as enzyme assays are employed. Enzyme assays are based on analysing the changes brought about on a substrate by an enzyme under defined conditions. Assays are often based on simplified reactions acting as substitutes for the reaction of interest. LÄS MER
4. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential
Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER
5. A biomimicking approach for hemicellulose processing
Sammanfattning : Lignocellulose can become the best opportunity for the society to reduce its dependency on the harmful petroleum based products as well as to produce clean energy. In each part of the production cycle, biomass based products have a better environmental profiles than their petroleum based counterparts. LÄS MER
