Gene expression of M. acetivorans producing ANME-1 Mcr during growth on methane vs. growth on methanol

Project description:Our goal is to convert methane efficiently into liquid fuels that may be more readily transported. Since aerobic oxidation of methane is less efficient, we focused on anaerobic processes to capture methane, which are accomplished by anaerobic methanotrophic archaea (ANME) in consortia. However, no pure culture capable of oxidizing and growing on methane anaerobically has been isolated. In this study, Methanosarcina acetivorans, an archaeal methanogen, was metabolically engineered to take up methane, rather than to generate it. To capture methane, we cloned the DNA coding for the enzyme methyl-coenzyme M reductase (Mcr) from an unculturable archaeal organism from a Black Sea mat into M. acetivorans to effectively run methanogenesis in reverse. The engineered strain produces primarily acetate, and our results demonstrate that pure cultures can grow anaerobically on methane.

Electron acceptor-dependent identification of key anaerobic toluene degraders at a tar-oil contaminated aquifer by Pyro-SIP

Project description:Bioavailability of electron acceptors is probably the most limiting factor in the restoration of anoxic, contaminated environments. The oxidation of contaminants such as aromatic hydrocarbons, particularly in aquifers, often depends on the reduction of ferric iron or sulphate. We have previously detected a highly active fringe zone beneath a toluene plume at a tar-oil contaminated aquifer in Germany, where a specialized community of contaminant degraders co-dominated by Desulfobulbaceae and Geobacteraceae had established. Although on-site geochemistry links degradation to sulphidogenic processes, dominating catabolic (benzylsuccinate synthase alpha-subunit, bssA) genes detected in situ appeared more related to those of Geobacter spp. Therefore, a stable isotope probing (SIP) incubation of sediment samples with 13C7-toluene and comparative electron acceptor amendment was performed. We introduce pyrosequencing of templates from SIP microcosms as a powerful new strategy in SIP gradient interpretation (Pyro-SIP). Our results reveal the central role of Desulfobulbaceae for sulphidogenic toluene degradation in situ, and affiliate the detected bssA genes to this lineage. This, and the absence of 13C-labelled DNA of Geobacter spp. in SIP gradients preclude their relevance as toluene degraders in situ. In contrast, Betaproteobacteria related to Georgfuchsia spp. became labelled under iron-reducing conditions. Furthermore, secondary toluene degraders belonging to the Peptococcaceae detected in both treatments suggest the possibility of functional redundancy amongst anaerobic toluene degraders on site. 2 samples examined from the different electron-acceptors (sulphate or ferric iron) incubates at the time point of maximal toluene degradation.

Transcriptional analysis of respiratory pathways in the hyperthermophilic crenarchaeon Pyrobaculum aerophilum

Project description:We compared global transcriptional patterns in Pyrobaculum aerophilum cultures with oxygen, nitrate, arsenate and ferric iron as respiratory electron acceptors to identify genes and regulatory patterns that differentiate these pathways. Keywords: Time course study with different respiratory electron acceptors To focus the microarrays on genes that are specifically affected by changes in terminal electron acceptors we analyzed gene expression in time courses with cultures shifted from aerobic growth to either NO3-, As(V), Fe(III)-citrate, or additional O2. Gene expression and substrate usage were measured at three time points (2.5, 4.5, and 7.5 hours), allowing sufficient time for changes in gene expression, while restricting cultures to a maximum of one or two cell divisions.
