Sammanfattning : With a metal removal process based on precipitation aimed atthe purification of pulping effluent as a starting point, theinfluence of carboxylic acids on calcium carbonateprecipitation has been studied. The chosen carboxylic acids canact as more or less strong complexing agents for aqueouscalcium, just as many compounds found in pulping liquors. LÄS MER
Sammanfattning : Bacillus subtilis can grow on glycerol or glycerol-3-phosphate (G3P) as the sole carbon and energy source. The glpD gene encodes G3P dehydrogenase which is required for the catabolism of glycerol and G3P. LÄS MER
Sammanfattning : The main objective of this work was to investigate the ring-opening polymerizations of cyclic esters by enzyme catalysis and cationic activated monomer polymerization in the search for new polymer materials and fiber-based composites. Candida antarcica lipase B was used for end-functionalization of poly(ε-caprolactone) and in the copolymerization of D,L-lactide and ε-caprolactone. LÄS MER
Sammanfattning : Release factor 1 (RF1) is a ribosome-binding protein required for termination of translation in Escherichia coli. To study the effect of slow termination on protein synthesis, two isolated suppressors to a temperature sensitive (Ts) mutant allele of RF1 were studied. LÄS MER
Sammanfattning : In bacteria, tRNA molecules are produced as precursors with additional nucleotides both upstream and downstream of the tRNA coding sequence. To generate a mature tRNA, the endoribonuclease RNase P removes the upstream sequence, while a number of enzymes can remove the downstream sequence. LÄS MER
