Abstract (sommario):

ABSTRACTDirect interspecies electron transfer (DIET) is potentially an effective form of syntrophy in methanogenic communities, but little is known about the diversity of methanogens capable of DIET. The ability ofMethanosarcina barkerito participate in DIET was evaluated in coculture withGeobacter metallireducens. Cocultures formed aggregates that shared electrons via DIET during the stoichiometric conversion of ethanol to methane. Cocultures could not be initiated with a pilin-deficientG. metallireducensstrain, suggesting that long-range electron transfer along pili was important for DIET. Amendments of granular activated carbon permitted the pilin-deficientG. metallireducensisolates to share electrons withM. barkeri, demonstrating that this conductive material could substitute for pili in promoting DIET. WhenM. barkeriwas grown in coculture with the H2-producingPelobacter carbinolicus, incapable of DIET,M. barkeriutilized H2as an electron donor but metabolized little of the acetate thatP. carbinolicusproduced. This suggested that H2, but not electrons derived from DIET, inhibited acetate metabolism.P. carbinolicus-M. barkericocultures did not aggregate, demonstrating that, unlike DIET, close physical contact was not necessary for interspecies H2transfer.M. barkeriis the second methanogen found to accept electrons via DIET and the first methanogen known to be capable of using either H2or electrons derived from DIET for CO2reduction. Furthermore,M. barkeriis genetically tractable, making it a model organism for elucidating mechanisms by which methanogens make biological electrical connections with other cells.

Abstract (sommario):

ABSTRACTThe possibility that metatranscriptomic analysis could distinguish between direct interspecies electron transfer (DIET) and H2interspecies transfer (HIT) in anaerobic communities was investigated by comparing gene transcript abundance in cocultures in whichGeobacter sulfurreducenswas the electron-accepting partner for eitherGeobacter metallireducens, which performs DIET, orPelobacter carbinolicus, which relies on HIT. Transcript abundance forG. sulfurreducensuptake hydrogenase genes was 7-fold lower in cocultures withG. metallireducensthan in cocultures withP. carbinolicus, consistent with DIET and HIT, respectively, in the two cocultures. Transcript abundance for the pilus-associated cytochrome OmcS, which is essential for DIET but not for HIT, was 240-fold higher in the cocultures withG. metallireducensthan in cocultures withP. carbinolicus. The pilin genepilAwas moderately expressed despite a mutation that might be expected to represspilAexpression. Lower transcript abundance forG. sulfurreducensgenes associated with acetate metabolism in the cocultures withP. carbinolicuswas consistent with the repression of these genes by H2during HIT. Genes for the biogenesis of pili and flagella and severalc-type cytochrome genes were among the most highly expressed inG. metallireducens. Mutant strains that lacked the ability to produce pili, flagella, or the outer surfacec-type cytochrome encoded by Gmet_2896 were not able to form cocultures withG. sulfurreducens. These results demonstrate that there are unique gene expression patterns that distinguish DIET from HIT and suggest that metatranscriptomics may be a promising route to investigate interspecies electron transfer pathways in more-complex environments.

Abstract (sommario):

ABSTRACTDirect interspecies electron transfer (DIET) is an alternative to interspecies H2/formate transfer as a mechanism for microbial species to cooperatively exchange electrons during syntrophic metabolism. To understand what specific properties contribute to DIET, studies were conducted withPelobacter carbinolicus, a close relative ofGeobacter metallireducens, which is capable of DIET.P. carbinolicusgrew in coculture withGeobacter sulfurreducenswith ethanol as the electron donor and fumarate as the electron acceptor, conditions under whichG. sulfurreducensformed direct electrical connections withG. metallireducens. In contrast to the cell aggregation associated with DIET,P. carbinolicusandG. sulfurreducensdid not aggregate. Attempts to initiate cocultures with a genetically modified strain ofG. sulfurreducensincapable of both H2and formate utilization were unsuccessful, whereas cocultures readily grew with mutant strains capable of formate but not H2uptake or vice versa. The hydrogenase mutant ofG. sulfurreducenscompensated, in cocultures, with significantly increased formate dehydrogenase gene expression. In contrast, the transcript abundance of a hydrogenase gene was comparable in cocultures with that for the formate dehydrogenase mutant ofG. sulfurreducensor the wild type, suggesting that H2was the primary electron carrier in the wild-type cocultures. Cocultures were also initiated with strains ofG. sulfurreducensthat could not produce pili or OmcS, two essential components for DIET. The finding thatP. carbinolicusexchanged electrons withG. sulfurreducensvia interspecies transfer of H2/formate rather than DIET demonstrates that not all microorganisms that can grow syntrophically are capable of DIET and that closely related microorganisms may use significantly different strategies for interspecies electron exchange.

A growing body of evidence demonstrates that methanogenesis and Fe(III) reduction can occur simultaneously. However, environmental controls on interactions between each are poorly understood. In this study we considered pH as a control on interactions between Fe(III) reduction and methanogenesis in anoxic sediment bioreactors. The reactors consisted of 100mL of synthetic aqueous media, and 1 g of marsh sediment amended with goethite (1mmol). One set of reactors received acidic media (pH 6), and the other alkaline media (pH 7.5). Each set received media containing acetate (0.25 mM) to serve as an electron donor. Control reactors, deficient in acetate, were also included. We maintained a fluid residence time of 35 days by sampling and feeding the reactors every seven days. For pH 6.0 and pH 7.5 reactors, the measured pH of effluent samples averaged 6.33 and 7.37, respectively. The extent of Fe(III) reduction and methanogenesis varied considerably between each set of reactors. More Fe(III) was reduced in the pH 6 reactors (646.39 μmoles on avg.) than the pH 7.5 reactors (31.32 μmoles on avg.). Conversely, more methane formed in pH 7.5 reactors (127.5 μmoles on avg.) than the pH 6 reactors (78.9 μmoles on avg.). Alkalinity concentrations during the middle and end of the experiment averaged 9.6 meq/L and 5.2 meq/L in pH 6 and pH7.5 reactors, respectively Although much less Fe(III) reduction occurred in pH 7.5 reactors, the relative abundance of Fe(III) reducers in them decreased little from levels observed in the pH 6 reactors. Sequences classified within Geobacter, a genus of bacteria known primarily as dissimilatory metal reducers, accounted for 22% and 13.45% of the sequences in the pH 6 and pH 7.5 reactors and only 0.8% of the sequences in the marsh sediment inoculum. In contrast, sequences classified within orders of methanogens were low in abundance, making up only 0.47% and 1.04% of the sequences in the pH 6 and pH 7.5 reactors, respectively. Mass balance calculations demonstrate that the amount of electron donor consumed by each group varied considerably between the sets of reactors. Expressed as a quantity of acetate, the reactions consumed about 160μM of electron donor each in pH 6 reactors. In contrast, methanogenesis consumed over 30 times more electron donor than Fe(III) reduction in the pH 7.5 reactors. Thus, the results of our experiment indicate that the decrease in electron donor consumption by Fe(III) reduction at basic pH was nearly matched by the increase in electron donor consumption by methanogens. Results of geochemical modeling calculations indicate that more energy was available for Fe(III) reduction in the pH 6.0 reactors than the pH 7.5 reactors, matching variation in Fe(III) reduction rates, and that the density of sorbed ferrous iron was higher in pH 6 reactors than pH 7.5 reactors. Thus, the calculation results are consistent with bioenergetics, but not variation in ferrous iron sorption, as a potential mechanism driving variation in the balance between each reaction with pH.

Abstract (sommario):

Thermionic emission in vacuum could be a highly efficient cooler or power generator if the work function, the minimum work for electrons to go into vacuum, is around 0.3–0.4 eV for heat source at a temperature below 500C [Mahan, 1994]. Unfortunately, the work function of existing materials is currently above 1 eV. Theoretical and experimental studies have shown that the work function can be reduced to 0.3–0.4 eV if the distance between the two electrodes (cathode and anode) of the thermionic emission cooler/power generator is below 10 nm [Hishinuma, et al, 2001, 2003]. At this nanometer scale, electron transport between the two electrodes takes two paths: electron tunneling and thermionic emission. The combined physical processes result in a desired work function. However, maintaining a nanometer gap for two parallel plates within an area larger than 1 cm2 is a daunting task, if not impossible, especially if the power generator is mounted on a moving or vibrating device. Even a slight vibration or thermal expansion of the two plates (electrodes) could cause direct contact between the two plates (electrodes), and thus shorten the circuits. Thus vacuum thermionic power generator based on difficult to make and to operate [Tavkhelidze, et al., 2002]. In this study, we propose to use a solid insulating spacer for preventing the shortening and for feasibility of manufacturing. The spacer is less than 5nm, and electron transport as thermionic emission and tunneling concurrently. In this study, we first investigate electron and phonon transport in single-layer (spacer) double heterostructures by including the tunneling effects. It is found that single-layer generator can have a high efficiency, but small power intensity due to the small temperature difference between the two electrodes. We then investigate the efficiency of multilayer-layer power generator. Calculations show that the solid power generator operating at a temperature below 500°C, can have an efficiency of larger than 40% of the Carnot efficiency.
