2. 1. A long journey from bioanode to biocathode

   Author : Soroush Saheb Alam; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocathode; Bioelectrochemical system; Storage; Starvation; Microbial electrolysis cell; Bioanode; Microbial fuel cell; Mixed microbial communities; Hydrogenotrophic microorganisms;

   Abstract : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. READ MORE

4. 2. Bioelectrochemical Applications of Reactions Catalyzed by Immobilized Enzymes

   Author : Xiao-Jing Tang; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acetate Kinase.; NAD NADH recycling; Enzyme Electrodes; Enzyme reactors; Enzyme Immobilization; Electrochemical detection; Flow Injection Analysis; Analytical chemistry; Analytisk kemi;

   Abstract : The sensitivity of biosensors can be increased substantially by incorporation in a substrate recycling scheme. Based on the amplification of NAD+/NADH by the recycling reaction catalyzed by glycerol dehydrogenase (GDH) and diaphorase, NAD+/NADH can be determined amperometrically with around 1000 times higher sensitivity than for the substrate sensing mode.

5. 3. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode

   Author : Kamrul Hasan; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological photovoltaics; electron transfer; electrode; Rhodobacter capslatus; thylakoid membranes; cyanobacteria; algae; photosynthesis; light; photocurrent; electrochemistry;

   Abstract : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. READ MORE

6. 4. Electrochemistry of Heme Containing Enzymes - Fundamentals and Applications

   Author : Annika Lindgren; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phenol monitoring; spectroelectrochemistry; self-assembled monolayer; gold electrode; graphite electrode; direct electron transfer; cellobiose dehydrogenase; biosensor; peroxidase; kinetics; Electrochemistry; Elektrokemi;

   Abstract : The thesis is a bioelectrochemical study of heme enzymes, mainly peroxidases and cellobiose dehydrogenases (CDH). It covers both fundamental and applied aspects, viz. studies of the direct electron transfer and kinetics of enzymes on electrodes, and the development of amperometric enzyme-based biosensors.
