1. 21. Determination of protolytes by flow procedures : applications to liquors from the hydrometallurgical nickel industry

   Författare :Isel Gertrudis Cortés Nodarse; KTH; []
   Nyckelord :;

   Sammanfattning : The general intention of this work is to contribute inreplacing complicated and time consuming titration methods foracid/base determination in cases where a rapid answer is morevaluable than a very high accuracy. The versatility of FlowInjection Analysis (FIA) is utilised for the determination ofprotolyte compounds, considering their role in our daily lifeas well as in science and technology. LÄS MER

3. 22. Sensor Systems for Bioprocess Monitoring

   Författare :Helena Lidén; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER

4. 23. Development of a Process for Reducing the Content of b-N-Oxalyl a,b-Diamino Propionic Acid (b-ODAP) in Grass Pea (Lathyrus sativus) Seeds: Nutritional Consequences and Technological Aspects

   Författare :Girma Akalu; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; process optimization; functional properties; biological value; net protein utilization; starch digestibility; protein digestibility; Grass pea Lathyrus sativus ; b-ODAP; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : Grass pea (Lathyrus sativus) is a leguminous food crop, grown mainly in the tropical and subtropical regions. It has valuable nutrients, however consumption of the seeds is reported to cause lathyrism, due to the presence of a non-protein amino acid (?-ODAP). LÄS MER

5. 24. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

   Författare :Ratana Lawung; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. LÄS MER

7. 25. New Bioanalytical Approaches, Magneto Immunoassays and SIRE Technology Based Biosensors

   Författare :Kirstin Kriz; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; antigens; superparamagnetic nanoparticles; magnetic inductance transducer; competitive magneto immunoassay; enzymes; metabolites; differential measurements; SIRE; biosensor;

   Sammanfattning : This thesis presents two new technologies, SIRE technology based biosensors and magneto immunoassays, which can be used for bioanalytical applications. One of the main problems associated with biosensor technology is the instability of the recognition element since it is of biological origin and thus, has a limited lifetime. LÄS MER
