The aim of this project is to apply an innovative approach to the study of the antioxidant / antibacterial properties of plant extracts used in folk medicine using structure-based fractionation, characterization by multi-instrumental methods and evaluation of activity against Gram-negative bacteria (E. coli and B. burgdorferi).
Wood is the most abundant form of biomass used by industry and is the source of the three major biolpolymers in nature – cellulose, hemicellulose and lignin. While cellulose is responsible for about 40-50% of the dry weight of wood, lignin content varies from 10% to about 35% across species. For decades, lignin has been seen as a bothersome side-product that needs removal at all cost. However, in the last decade, due to its polyphenolic nature, lignin has emerged to the focus of attention as a renewable alternative to crude oil based chemistry. The project aims to develop technologies for the extaction and fractionation of lignin and cellulose derived from low valorization level bleached chemi-thermomechanical pulp or industrial wood-waste. The goal of the project is to develop practical and environmentally friendly functional materials (e.g. thermo isolators and surfactants). Also, the project will identify and characterize novel industrial enzymes from extreme thermophilic organisms.
