  2. 6. Xylan degradation by the thermophilic bacterium Rhodothermus marinus. Characterization and function of a thermostable xylanase

    Author : Eva Nordberg Karlsson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fed-batch cultivation; kraft pulp; bleaching; glycosyl hydrolase family 10; recombinant xylanase; polysaccharide binding domain; Biotechnology; Bioteknik;

    Abstract : A gene encoding a multidomain xylanase from the thermophilic bacterium Rhodothermus marinus has been cloned, sequenced and produced in Escherichia coli . The gene product was found to be a 109 kDa protein consisting of five domains. READ MORE

  4. 7. Heterologous expression, characterization and applications of carbohydrate active enzymes and binding modules

    Author : Åsa Kallas; Tuula T. Teeri; Edward A. Bayer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Populus; xyloglucan endotransglycosylase; carbohydrate binding modules; endo- 1; 4 -b-xylanase; Escherichia coli; Pichia pastoris; N-glycosylation; fiber analysis; Bioengineering; Bioteknik; Wood fibre and forest products; Träfiber- och virkeslära;

    Abstract : Wood and wood products are of great economical and environmental importance, both in Sweden and globally. Biotechnology can be used both for achieving raw material of improved quality and for industrial processes such as biobleaching. READ MORE

  5. 8. Prebiotic Oligosaccharides from Xylan: Heat Pretreatment, Xylanase Hydrolysis, Utilization by Potential Probiotics and Evaluation in a Mouse Study

    Author : Peter Falck; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; arabinoxylan; xylooligosaccharides; arabinoxylooligosaccharides; Bifidobacterium; Lactobacillus;

    Abstract : Modulation of the gut microbiota with prebiotic oligosaccharides from partially hydrolyzed xylans can be part of the solution for reducing the occurrence of many health problems such as diabetes, cardiovascular disease and cancer. Prebiotics are carbohydrates that selectively stimulate health beneficial bacteria in the colon, restoring homeostasis to the gut environment. READ MORE

  6. 9. Bioprocess Monitoring and Control in Pseudomonas cepacia and recombinant Escherichia coli cultivations

    Author : Anita Tocaj; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein L; expanded bed; flow-injection analysis; recombinant protein production; acetic acid; on-line measurements; Pseudomonas cepacia; recombinant Escherichia coli; Fed-batch cultivations; control strategies; xylanase deletion derivatives from Rhodothermus marinus; Biotechnology; Bioteknik;

    Abstract : The control of cultivation conditions and its influence on growth and production have been investigated. The use of fed-batch processes have been demonstrated for several cultivation systems and so has the use of different control signals in these systems. READ MORE

  7. 10. Bench-Scale Production of Heterologous Proteins from Extremophiles- Escherichia coli and Pichia pastoris based expression systems

    Author : Santosh Ramchuran; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glycoside hydrolase; Heterologous protein; High cell density cultivation Expression systems; Bioteknik; Biotechnology; Fed-batch;

    Abstract : Over the past few years considerable research attention has been assigned to extremophiles as sources of extremozymes due to their applicability in industrial processes, and the development of eco-friendly technologies. The establishment of efficient production strategies for heterologous proteins is an empirical process requiring broad background knowledge on available expression systems together with their major advantages and shortcomings.
