   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; Microbial fuel cell; Raman microscopy; BES; Geobacter sulfurreducens; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Since the 1900’s it has been known that microorganisms are capable of generating electrical power through extracellular electron transfer by converting the energy found organic compounds (Potter, 1911). Microbial fuel cells (MFCs) has garnered more attention recently, and have shown promise in several applications, including wastewater treatment (Yakar et al. LÄS MER

3. 22. Sound, Light and Electricity : as applications and analysis techniques to study metabolic effect and biofilm characterization of Geobacter sulfurreducens

   Författare :Adolf Krige; Paul Christakopoulos; Ulrika Rova; Ashley Franks; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; Microbial fuel cell; Raman microscopy; BES; Geobacter sulfurreducens; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : ElectricityBio-electrochemical systems such as microbial fuel cells (MFCs) and microbial electrolysis cells have shown promise in wastewater treatment, bioremediation, desalination, carbon sequestration and as an alternative, renewable energy source. MFCs produces electricity via anaerobic oxidation of substrates with the subsequent extracellular electron transfer to an electrode. LÄS MER

4. 23. Theoretical Studies of Cytochrome P450

   Författare :Patrik Rydberg; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; Proteins; enzymology; Proteiner; enzymologi; Theoretical chemistry; transition-state force field; peroxidase; theoretical chemistry; molecular dynamics; density functional theory; cytochrome P450; porphyrin; haem; heme; kvantkemi; Teoretisk kemi;

   Sammanfattning : The cytochromes P450 are a large enzyme family that is found in all living organisms and takes part in both endogenous and exogenous metabolism. They are primarily mono-oxygenases and perform a wide range of reactions. LÄS MER

5. 24. Heme A synthase from Bacillus subtilis and Aeropyrum pernix

   Författare :Anna Lewin; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heme A synthesis; heme A; heme A synthase; CtaA; cCtaA; cytochrome a; Aeropyrum pernix; Bacillus subtilis;

   Sammanfattning : Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. LÄS MER

7. 25. The Physiological Cost of Antibiotic Resistance

   Författare :Mirjana Macvanin; Diarmaid Hughes; Stanley Maloy; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; fusidic acid; fitness cost; protein synthesis; EF-G; ppGpp; RpoS; oxidative stress; heme; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

   Sammanfattning : Becoming antibiotic resistant is often associated with fitness costs for the resistant bacteria. This is seen as a loss of competitiveness against the antibiotic-sensitive wild-type in an antibiotic-free environment. LÄS MER
