Dual bioaugmentation with Desulfitobacterium hafniense Y51 and redox-trained fermenting communities for decontamination of PCE polluted river sediment: a microcosm study

ABSTRACT: The physiology of D. hafniense strain Y51 under close to natural conditions were examined: D. hafniense Y51 was subjected to a variety of limiting conditions (carbon or electron acceptor) or ammonium deprivation, in chemostat. Its physiology was assessed by transcriptomic and proteomic analyses and compared to that in batch culture. Electron donor/acceptor-limited growth conditions cause a switch to alternative metabolic pathways allowing the organism with a capacity to survive in polluted environments and with a readiness to use alternative electron acceptors such as PCE; (ii) nitrogen limitation induces nitrogen fixation implying a robustness vis-a-vis ammonia shortage; (iii) limiting conditions trigger a general stress response that should enable the organism to cope with even more environmental constraints.

Transcription profiling of G sulfurreducens GGS Fe(III) vs fumarate

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 30 °C in chemostats, (see Esteve-Núñez, A., M. M. Rothermich, M. Sharma, and D. R. Lovley. 2004. Growth of Geobacter sulfurreducens under nutrient-limiting conditions in continuous culture. Environ. Microbiol.:in press. for more information), with acetate (5 mM) as the electron donor and Fe(III) citrate (55 mM) or fumarate (27.5 mM) as the electron acceptor. Under these conditions acetate is the substrate limiting growth. Cultures were maintained at a dilution rate of 0.05 h-1 for 5 culture vessel volumes to ensure that cells were at steady-state prior to harvesting. Cells were harvested 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 acetate limited growth with fumarate as the electron acceptor and three cultures of acetate limited growth with Fe(III) as the electron acceptor were grown. Each culture vessel was harvested and extracted for total RNA separately to produce three biological replicates for this experiment.

Transcription profiling of G sulfurreducens GGS nitrogen fixation

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 30 °C in chemostats, as previously described (for more information see Esteve-Núñez, A., M. M. Rothermich, M. Sharma, and D. R. Lovley. 2004. Growth of Geobacter sulfurreducens under nutrient-limiting conditions in continuous culture. Environ. Microbiol.:in press.), with acetate (5 mM) as the electron donor and fumarate (27.5 mM) as the electron acceptor. For growth in the absence of fixed nitrogen, the ammonium chloride (4.7 mM) was omitted from the medium and fumarate served as the electron acceptor. Therefore, cultures with ammonium chloride were limited by acetate while cultures without ammonium chloride were limited by nitrogen. Cultures were maintained at a dilution rate of 0.05 h-1 for 5 culture vessel volumes to ensure that cells were at steady-state prior to harvesting. Cells were harvested 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. Cells grown in the absence of ammonium had acetylene reduction rates of 0.012 nmol/hr compared to 0.003 nmol/hr in ammonium-grown cells, providing evidence that these cells were fixing nitrogen.. The steady-state concentration of cells in the nitrogen-fixing chemostats (0.178 mg/mL + 0.011; mean + standard deviation, n=3) was significantly lower than chemostats provided with ammonium (0.45 mg/mL + 0.007). Three cultures of acetate limited growth with fumarate as the electron acceptor and three cultures of nitrogen limited growth with fumarate as the electron acceptor were grown. Each culture vessel was harvested and extracted for total RNA separately to produce three biological replicates for this experiment.

Expression data from Saccharomyces cerevisiae

Project description:In this study we focus on two Saccharomyces cerevisiae strains with varying production of heterologous α-amylase and we compare the metabolic fluxes and transcriptional regulation at aerobic and anaerobic conditions, in particular with the objective to identify the final electron acceptor for protein folding. We found that anaerobic conditions showed high amount of amylase productions when comparing to aerobic conditions and the genome-scale transcriptional analysis suggested that genes related to the endoplasmic reticulum (ER), lipid synthesis and stress responses were generally up-regulated at anaerobic conditions. Moreover, we proposed a model for the electron transfer from ER to the final electron acceptor, fumarate under anaerobic conditions.

Transcriptome analysis of Paracoccus denitrificans following exposure to hexavalent chromium under aerobic and anoxic conditions

Project description:Suspended cell studies were performed to document whole-genome transcriptional profiles as a function of Cr(VI) reduction under different electron accepting conditions. Cell suspension studies were performed in 250 mL serum bottles for two conditions: 1) under anoxic condition with lactate as carbon source and nitrate as electron acceptor, and 2) under aerobic condition with lactate as carbon source and oxygen as electron acceptor. The initial Cr(VI) and nitrate concentrations were 1000 μg/L and 40 mg N/L, respectively. Samples from both the conditions were collected after 5 hours and the cell pellet was saved at -80°C.

FCV-CNRS Aerobic-Anaerobic A. ferrooxidans

Project description:Transcriptomic study of A. ferrooxidans was explored either during aerobic growth with sulfur as an electron source and oxygen as final electron acceptor or in anaerobic conditions with ferric iron as the final electron receptor. Differential RNA levels were related to changes in cellular functions that were used to develop a preliminary model for A. ferrooxidans electron transport during dissimilatory ferric iron reduction.
