1. 36. Short-term adaptation of S. cerevisiae to lignocellulosic inhibitors: Underlying metabolic and physiological changes

   Författare :Marlous van Dijk; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic inhibitor tolerance; second generation bioethanol; short-term adaptation; differential gene expression; industrial yeast strains;

   Sammanfattning : The limited tolerance of Saccharomyces cerevisiae (budding yeast) to inhibitors present in lignocellulosic hydrolysates is a major challenge in second-generation bioethanol production. Short-term adaptation of the yeast to lignocellulosic hydrolysates during cell propagation has been shown to improve its tolerance, and thus its performance in lignocellulose fermentation. LÄS MER

3. 37. Metabolic Engineering of Recombinant Protein Production by Saccharomyces cerevisiae

   Författare :Zihe Liu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recombinant protein production; genome sequencing; DNA microarray; insulin precursor; growth rate; UV mutation; yeast; anaerobic electron acceptor; secretory pathway; unfolded protein response; metabolic engineering; systems biology; α-amylase;

   Sammanfattning : The yeast Saccharomyces cerevisiae is a widely used cell factory for the production of fuels, chemicals, and it also provides a platform for the production of many heterologous proteins of medical or industrial interest. In this thesis, random and rational approaches, such as vector design, host engineering, fermentation analysis, UV Mutation, coupled with high-throughput systems biology techniques (including whole genomic sequencing, microarray analysis and flux analysis) and integrated analysis (Reporter feature technique), were employed to engineer cellular properties more effectively and purposefully to construct cell factories for protein production.

4. 38. Development of biocatalytic processes for selective antioxidant production

   Författare :Io Antonopoulou; Paul Christakopoulos; Ulrika Rova; Evangelos Topakas; Anne S. Meyer; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and sugar residues in plant cell walls.

5. 39. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

   Författare :Simon Bengtsson; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

   Sammanfattning : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. LÄS MER

7. 40. Industrial work groups : the impact of job design, leader support and group processes on initiative and self-organization

   Författare :Agneta Brav; Annika Lantz; Kerstin Isaksson; Bo Ekehammar; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industrial work groups; job design; support from leader; group processes; potency; group initiative; self-organizational activities; Psychology; Psykologi; Psychology; Psykologi;

   Sammanfattning : From an organizational perspective the issue of which organizational solutions will benefit productivity, efficiency and the innovation process is central. Work groups can be an effective means. LÄS MER
