Engineered cell elongation promotes extracellular electron transfer of Shewanella oneidensis

(Submitter supplied) To investigate how cell elongation impacts extracellular electron transfer (EET) of electroactive microorganisms (EAMs), the division of model EAM Shewanella oneidensis MR-1 was engineered by reducing the formation of cell divisome. Specially, by blocking the translation of division proteins via anti-sense RNAs or expressing division inhibitors, the cellular length and output power density were all increased. more...

Supplementation with amino acid sources facilitates fermentative growth of Shewanella oneidensis MR-1 in defined media

(Submitter supplied) Shewanella oneidensis MR-1 is a facultative anaerobe that grows by respiration using a variety of electron acceptors. This organism serves as a model to study how bacteria thrive in redox-stratified environments. A glucose-utilizing engineered derivative of MR-1 has been reported to be unable to grow in glucose minimal medium (GMM) in the absence of electron acceptors, despite this strain having a complete set of genes for reconstructing glucose to lactate fermentative pathways. more...

Molecular mechanism of zero valent iron-enhanced microbial azo reduction in Shewanella decolorationis S12

(Submitter supplied) Here, we established a successive Fe0-enhanced microbe system to remove azo dye (a typical organic pollutant) by Shewanella decolorationis S12 (S. decolorationis S12, an effective azo dye degradation bacterium) and examined the gene expression time course (10, 30, 60, and 120 min) in whole genome transcriptional level. Comparing with the treatment without ZVI, approximately 8% genes affiliated with 10 different gene expression profiles in S. more...

Reduction of alternative electron acceptors drives biofilm formation in Shewanella algae

(Submitter supplied) Shewanella spp. possess a broad respiratory versatility, which contributes to the occupation of hypoxic/anoxic environmental or host-associated niches. Here we observed a strain-specific induction of biofilm formation in response to supplementation with the anaerobic electron acceptors dimethyl sulfoxide (DMSO) and nitrate in a panel of Shewanella algae isolates. The respiration-driven biofilm response is not observed in DMSO and nitrate reductase deletion mutants of the type strain S. more...

Identification of an ECF sigma factor that facilitates electroactive biofilm formation by Shewanella oneidensis MR-1: Experiment 2

(Submitter supplied) Shewanella oneidensis MR-1 was grown on electrodes in electrochemical flow cells (EFC), and the transcriptome profiles of electrode-attached MR-1 cells were compared under electrolyte-flow and static (non-flow) conditions. The results revealed that the SO_3096 gene encoding a putative extracytoplasmic function (ECF) sigma factor, as well as genes related to cyclic-di-guanosine monophosphate and flagella synthesis (e.g., SO_3556 and flrC) and c-type cytochrome maturation (dsbD), was significantly up-regulated under the electrolyte-flow condition. more...

Changes in Shewanella baltica transcriptome upon cold stress

(Submitter supplied) In this work we analyzed changes in gene espression in Shewanella baltica upon cold stress. In order to imitate natural environment, we cultured bacteria in the Instant Ocean medium in a chemostat. Samples were collected after 90 and 180 minutes of cold stress and analyzed by RNA sequencing. The transcriptomic response could be characterized as global downregulation of gene expression (613 genes downregulated) and we found only 242 genes which were upregulated. more...

Overexpression of the adenylate cyclase gene cyaC facilitates current generation by Shewanella oneidensis in bioelectrochemical systems

(Submitter supplied) 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. more...

Adaptive Responses of Shewanella decolorationis to the Toxic Organic Extracellular Electron Acceptor in Anaerobic Respiration

(Submitter supplied) Bacterial anaerobic respiration using extracellular electron acceptor plays a predominant role in global biogeochemical cycles. However, the bacterial adaptive mechanisms to the toxic organic pollutant as the extracellular electron acceptor during anaerobic respiration is not clear, which limits us to optimize the strategies for the bioremediation of contaminated environment. Here, we report the physiological characteristics and the global gene expression of an ecologically successful bacterium Shewanella decolorationis S12 when using a typical toxic organic pollutant, amaranth, as the extracellular electron acceptor. more...

Differences in Shewanella algae C6G3 transcriptomes according to nature of electron acceptor (MnIV/NO3)

(Submitter supplied) Shewanella algae C6G3 can conduct dissimilative nitrate reduction into ammonium and MnIV reduction. This bacteria have the unusual ability to produce anaerobically nitrite from ammonium in the presence of MnIV. This property may explain NO2/3- accumulation observed in some anaerobic zones of marine sediments. To gain insight into their metabolic capabilities, global mRNA expression patterns were investigated by RNA-seq and qRT-PCR in cells growing with lactate and ammonium as carbon and nitrogen sources and with MnIV or nitrate as electron acceptors. more...

Electrochemically active bacteria sense electrode potentials for regulating catabolic pathways

(Submitter supplied) Electrochemically active bacteria (EAB) receive considerable attention for their utility in bioelectrochemical processes. Although electrode potentials are known to affect the metabolic activity of EAB, it is unclear whether EAB are able to sense and respond to electrode potentials. Here, we show that, in the presence of a high-potential electrode, a model EAB Shewanella oneidensis MR-1 can utilize NADH-dependent catabolic pathways and a background formate-dependent pathway to achieve high growth yield. more...

CpdA is involved in amino acid metabolism in Shewanella oneidensis MR-1

(Submitter supplied) Cyclic 3',5'-adenosine monophosphate (cAMP) phosphodiesterase (CPD) is an enzyme that catalyzes the hydrolysis of cAMP, a signaling molecule affecting diverse cellular and metabolic processes in bacteria. Some CPDs are also known to function in cAMP-independent manners, while their physiological roles remain largely unknown. Here, we investigated physiological roles of CPD in Shewanella oneidensis MR-1, a model environmental bacterium, and report that CPD is involved in amino-acid metabolism. more...
