Transcription profiling of Geobacter sulfurreducens grown in batch culture with either ferric citrate or graphite anodes as the electron acceptor

Project description:G. sulfurreducens (ATCC #51573) was obtained from the laboratory culture collection of Dr. Derek Lovley. Cells were grown under strict anaerobic conditions at 23 °C in batch culture. Both control and experimental populations were grown with 10mM acetate as the electron donor while Fe(III) as 55 mM ferric citrate served as the electron acceptor for the control populations and graphite anodes as the electron acceptor for the experimental populations. Controls populations were harvested at a concentration of 30 mM Fe(II). Fuel cell power output was monitored by measuring the voltage across a known resistance in the fuel cell and experimental populations were harvested when current production reached a steady state of 0.6 milliamperes. Cells were harvested at log phase by centrifugation at 4 °C and the cell pellet was flash-frozen in liquid nitrogen and then stored at -80 °C prior to RNA extraction. Three cultures of control and experimental populations were collected. Each culture vessel was harvested and extracted for total RNA separately to produce three biological replicates for this experiment. Additional information regarding the fuel cell experimental set up and culture conditions for this experiment can be found in both the current reference and the following reference: Bond DR and Lovley DR. Electricity production by Geobacter sulfurreducens attached to electrodes. 2003. Applied and Environmental Microbiology 69: 1548-1555.

Geobacter sulfurreducens biofilm iTRAQ analysis

Project description:Geobacter sulfurreducens is a dissimilatory metal-reducing bacterium capable of forming thick electron-conducting biofilms on solid electrodes in the absence of alternative electron acceptors. The remarkable ability of such biofilms to transfer electrons, liberated from soluble organic electron donors, over long distances has attracted scientific interest as to the mechanism for this process, and technological interest for application to microbial fuel and electrolysis cells and sensors. Here, we employ comparative proteomics to identify key metabolic pathways involved in G. sulfurreducens respiration by planktonic cells versus electron-conducting biofilms, in an effort to elucidate long-range electron transfer mechanisms.

Transcription profiling of wild type G. sulfurreducens DL1 strain and mutant DLCN16 (delta-rpoS::Km) using ferric citrate as an electron acceptor

Project description:Wild type G. sulfurreducens DL1 strain (see Caccavo, F., Jr., D. J. Lonergan, D. R. Lovley, M. Davis, J. F. Stolz, and M. J. McInerney. 1994. Geobacter sulfurreducens sp. nov., a hydrogen- and acetate-oxidizing dissimilatory metal-reducing microorganism. Appl Environ Microbiol 60:3752-9. see also Coppi, M. V., C. Leang, S. J. Sandler, and D. R. Lovley. 2001. Development of a genetic system for Geobacter sulfurreducens. Appl Environ Microbiol 67:3180-7.) and DLCN16 mutant (.rpoS::Km) (see Nuñez, C., L. Adams, S. Childers, and D. R. Lovley. 2004. The RpoS sigma factor in the dissimilatory Fe(III)-reducing bacterium Geobacter sulfurreducens. J Bacteriol 186:5543-6.) were grown under anaerobic conditions at 30 °C in continuous culture with a 200 ml working volume as previously described (see Esteve-Nunez, A., M. Rothermich, M. Sharma, and D. Lovley. 2005. Growth of Geobacter sulfurreducens under nutrient-limiting conditions in continuous culture. Environ Microbiol 7:641-8.). Cells were cultured at a growth rate of 0.05 h-1, steady-state cell growth was obtained after 5 volume refills and was confirmed by a constant cell density and concentrations of Fe(II). Acetate (5.5 mM) was the electron donor and the limiting substrate. The electron acceptor was Fe(III)-citrate (60mM). Two biological replicates of control and treatment cells were obtained to produce hybridizations for this experiment.
