The aim of the work presented in this thesis was to improve ethanol formation from xylose in recombinant Saccharomyces cerevisiae strains. This was achieved by decreasing the xylitol by-product formation. Gre3p is the major xylose-reducing enzyme in S. cerevisiae. Ypr1p, Gcy1p and the protein encoded by YJR096w also have the ability to reduce xylose in cell extracts. Furthermore, Gre3p, Ypr1p, Gc

Results of molecular phylogenetic analysis after nuclear (18S LSU, ITS1/ITS2), mitochondrial (12S and 23S SSU) and chloroplast DNA of lichen-forming fungi, symbiotic and terrestrial algae as well as microscopic filamentous fungi obtained for the first time in Ukraine are compared with recent data on morphology, anatomy and biochemical characters. Taxonomical treatment of several groups of lichen-f

This dissertation examines the influence of lexical-semantic representations, conceptual similarity, and contextual fit on the processing of coordinated verb phrases. The study integrates information gleaned from current linguistic theory with current psycholinguistic approaches to examining the processing of coordinated verb phrases. It has been claimed that in coordinated phrases, one conjunct m

The purpose of this volume is to show how different national contexts affected the proliferation of anti-Catholic messages over the course of four centuries of European history, from 1600 to 2000. Factors such as the legal status of various faiths and their opportunities for proselytising, the relation between state and church, transnational cultural relations, and the development of different med

One of the most common Neolithic tool types in Scandinavia which is available to us for study today is the axe. Judging by the thousands of such axes found in museum collections, this tool was an important part of Neolithic man's toolkit. While most of the axes which are considered primarily work axes (as opposed to the more ceremonial so-called battle axes) are made of flint, other, non-flint mat

The adsorption at solid/liquid interfaces of b-lactoglobulin (b-lg) A and B have been studied by in situ ellipsometry and related to the properties of these proteins in solution. At low temperatures (4-25°C) the adsorption of the b-lgs was found to be highly related to their self-association behaviour in solution. The adsorption isotherms at 25°C, both on methylated and hydrophilic silica, showed

A sustainable development of the built environment asks for changes in urban residents’ mobility patterns. The extensive use of the car contributes to sedentary lifestyle and negative environmental impact in many respects. Children living in urban areas are faced with limits of their independent use of the environment both in terms of travel and outdoor play. Many parents hold favourable attitudes
