Project description:. In this study we show successful use of SWATH-MS for quantitative proteomic analysis of a microbial electrochemically active biofilm. Shewanella oneidensis MR-1 was grown on carbon cloth electrodes under continuous anodic electrochemical polarizations in a bioelectrochemical system. Using lactate as the electron donor, anodes serving as terminal microbial electron acceptors were operated at three different electrode potentials (+0.71V, +0.21V & -0.19V vs. SHE) and the development of catalytic activity was monitored by measuring the current traces over time. Once maximum current was reached (usually within 21-29 hours) the electrochemical systems were shut off and biofilm proteins were extracted from the electrodes for proteomic assessment.

Project description:The increased urban pressures are often associated with specialization of microbial communities. Microbial communities being a critical player in the geochemical processes, makes it important to identify key environmental parameters that influence the community structure and its function.In this proect we study the influence of land use type and environmental parameters on the structure and function of microbial communities. The present study was conducted in an urban catchment, where the metal and pollutants levels are under allowable limits. The overall goal of this study is to understand the role of engineered physicochemical environment on the structure and function of microbial communities in urban storm-water canals.

Project description:Four stable and robust TCE-dechlorinating microbial communities were enriched from TCE-contaminated groundwater under four different conditions exploring two parameters, high and low methanogenic activity (Meth and NoMeth), with and without vitamin B12 supplement (MethB12 and NoMethB12, Meth and NoMeth, respectively). Identical amounts of lactate (2.7 mmol) and TCE (20 μl) were supplied as electron donor and electron acceptor. All four cultures were capable of reductively dechlorinating TCE to VC and ethene. Genomic DNA of the four enrichments was applied on a quad-Dhc-genome microarray in order to characterize the gene content of Dehalococcoides species present in the four enrichments

Project description:Desulfovibrio vulgaris Hildenoborough was incubated in an H-type electrochemical reactor for 7 days on an indium-tin doped oxide electrode poised at −0.2 V (versus standard hydrogen electrode), which served as the sole electron donor. As a negative open circuit (without electrode) control, cells were incubated in a glass vial in the absence of an electrode. Total RNA was extracted from cells after incubation, and RNA fragments were purified and transcribed into cDNA. cDNA was sequenced by NovaSeq 6000 System.

Project description:Electrochemically active bacteria (EAB) are capable of electrochemical interactions with electrodes via extracellular electron transfer (EET) pathways and serve as essential components in bioelectrochemical systems. Previous studies have suggested that EAB, such as Shewanella oneidensis MR-1, use cyclic AMP (cAMP) receptor proteins for coordinately regulating the expression of catabolic and EET-related genes, allowing us to hypothesize that the intracellular cAMP concentration is an important factor determining electrochemical activities of EAB. The present study constructed an MR-1 mutant, cyaC-OE that overexpressed cyaC, a gene encoding a membrane-bound class III adenylate cyclase, and examined its electrochemical and transcriptomic characteristics. We show that intracellular cAMP concentration in cyaC-OE is more than double that in wild-type MR-1, and cya-OE generates approximately two-fold higher current in BES than the wild type. In addition, the expression of genes involved in EET and anaerobic carbon catabolism is up-regulated in cya-OE as compared to that in the wild type. These results suggest that enhancement of the intracellular cAMP level is a promising approach for constructing an EAB with high catabolic and electrochemical activities.
