Abstract Microbial phototrophs, key primary producers on Earth, use H 2 O, , S and other reduced inorganic compounds as electron donors. Here we describe a form of metabolism linking anoxygenic photosynthesis to anaerobic respiration that call ‘syntrophic photosynthesis’. We show photoautotrophy in the green sulfur bacterium Prosthecochloris aestaurii can be driven by either electrons from solid electrode or acetate oxidation via direct interspecies transfer heterotrophic partner bacterium,...
Simultaneous electricity generation and distillery wastewater (DWW) treatment were accomplished using a thermophilic microbial fuel cell (MFC). The results suggest that MFCs, which require less energy for cooling the DWW, can achieve high efficiency also reduce sulfate along with oxidizing complex organic substrates. generated current density (2.3 A/m(2)) power (up to 1.0 W/m(2)) higher than previous wastewater-treating MFCs. significance of Coulombic (CE; up 89%) indicated electrical was...
Microbial fuel cells (MFCs) have been used to enrich microbes oxidizing formate with concomitant electricity generation. Medium containing was fed continuously MFCs. MFCs showed approximately 1 mA of current after 4 months operation. Over 90% supplied removed in MFCs, while Coulombic efficiency only 5.3% indicating substantial electron and energy losses rather than Denaturing gradient gel electrophoresis (DGGE) that a formate-utilizing acetogenic bacterium (Acetobacterium sp.), an...
Inability to culture the phloem-restricted alpha-proteobacterium "Candidatus Liberibacter asiaticus" ("Ca. L. asiaticus") or closely related species ("Candidatus americanus" and africanus") that are associated with Huanglongbing (HLB) hampers development of effective long-term control strategies for this devastating disease. Here we report successful establishment maintenance host-free "Ca. cultures, bacterium growing within cultured biofilms derived from infected citrus tissue. The were...
Phototrophic microbial mats frequently exhibit sharp, light-dependent redox gradients that regulate respiration on specific electron acceptors as a function of depth. In this work, benthic phototrophic mat from Hot Lake, hypersaline, epsomitic lake located near Oroville in north-central Washington, was used to develop microscale electrochemical method study local transfer processes within the mat. To characterize physicochemical variables influencing transfer, we initially quantified...
Abstract. Nitrous acid (HONO) is an important atmospheric gas given its contribution to the cycles of NOx and HOx, but role in global photochemistry not fully understood. This study implemented three pathways HONO formation chemistry–climate model CHASER (MIROC-ESM) explore physical phenomena: gas-phase kinetic reactions (GRs), direct emission (EM), heterogeneous on cloud aerosol particles (HRs). We evaluated simulations by aircraft-based measurements from EMeRGe-Asia-2018 (Effect Megacities...
Sediment microbial fuel cells (SMFCs) are being developed as potential energy sources where remote sensing and monitoring would be useful. Several harvesting techniques for SMFCs have emerged, but effects of these different strategies on startup, performance, community not well understood. We investigated by comparing a continuous (CEH) strategy with an intermittent (IEH) strategy. During IEH systems immediately produced higher power were cathode limited. CEH exhibited gradual increase...
Abstract. This study uses a chemistry–climate model CHASER (MIROC) to explore the roles of heterogeneous reactions (HRs) in global tropospheric chemistry. Three distinct HRs N2O5, HO2, and RO2 are considered for surfaces aerosols cloud particles. The simulation is verified with EANET EMEP stationary observations; R/V Mirai ship-based data; ATom1 aircraft measurements; satellite observations by OMI, ISCCP, CALIPSO-GOCCP; reanalysis data JRA55. chemistry facilitates improvement performance...
Plant pathogenic bacteria interact with their insect host(s)/vector(s) at the cellular and molecular levels. This interaction may alter physiology of vector, which also promote growth transmission bacterium. Here we studied effect "Candidatus Liberibacter asiaticus" ("Ca. L. asiaticus") on physiochemical conditions within its Asian citrus psyllid (ACP), whether these changes were beneficial for pathogen. The local microenvironments inside ACPs quantified using microelectrodes. average...
Phototrophic microbial mats are among the most diverse ecosystems in nature. These systems undergo daily cycles redox potential caused by variations light energy input and metabolic interactions species. In this work, solid electrodes with controlled potentials were placed under to study electron transfer processes between electrode mat. The phototrophic mat was harvested from Hot Lake, a hypersaline, epsomitic lake located near Oroville (Washington, USA). We operated two reactors: graphite...
Fumarate is one of the terminal electron acceptors which can be used by microorganisms growing as biofilms. Mass transport in biofilms dominated diffusion, creates a fumarate concentration gradient and could limiting factor for growth respiring on fumarate. Bulk solution measurements cannot to determine limitations fumarate-respiring Therefore, new approaches are needed measuring The goal this study was develop microbiosensor situ depth profiling working principle correlation between current...
