  • boosting the adoption and the reliability of renewable energy sources mitigating the large scale wind power intermittency through vehicle to grid technology
    Energy, 2017
    Co-Authors: Yang Lu-zhao, Mehdi Noori, Omer Tatari
    Abstract:

    The integration of wind energy in the electricity sector and the adoption of electric vehicles in the transportation sector both have the potential to significantly reduce greenhouse gas emissions individually as well as in tandem with Vehicle-to-Grid technology. This study aims to evaluate the greenhouse gas emission savings of mitigating intermittency resulting from the introduction of wind power through Vehicle-to-Grid technologies, as well as the extent to which the marginal electricity consumption from charging an electric vehicle fleet may weaken this overall environmental benefit. To this end, the comparisons are conducted in seven independent system Operator Regions. The results indicate that, in most cases, the emission savings of a combination of wind power and Vehicle-to-Grid technology outweighs the additional emissions from marginal electricity generation for electric vehicles. In addition, the fluctuations in newly-integrated wind power could be balanced in the future using EVs and V2G technology, provided that a moderate portion of EV owners is willing to provide V2G services. On the other hand, such a combination is not favorable if the Vehicle-to-Grid service participation rate is less than 5% of all electric vehicle owners within a particular region.

  • cloning sequence and footprint analysis of two promoter Operators from corynebacterium diphtheriae that are regulated by the diphtheria toxin repressor dtxr and iron
    Journal of Bacteriology, 1994
    Co-Authors: Michael P Schmitt, Randall K Holmes
    Abstract:

    DtxR is an iron-dependent sequence-specific DNA-binding protein that binds to the tox Operator, an inverted-repeat nucleotide sequence located upstream from the diphtheria toxin gene. In this study, two additional iron-regulated promoter/Operator sequences (IRP1 and IRP2) that are controlled by DtxR were cloned from the chromosome of Corynebacterium diphtheriae and characterized. Operon fusions to lacZ were used to analyze expression from IRP1 and IRP2 in Escherichia coli. Transcription from both promoters was strongly repressed in high-iron medium in the presence of the cloned dtxR gene; however, transcription in the absence of dtxR was 50- to 100-fold greater, regardless of the iron concentration. Purified DtxR altered the electrophoretic mobility of DNA fragments carrying IRP1 or IRP2, and the nucleotide sequences of the two promoter/Operator Regions indicated that they are both homologous with the tox Operator. DtxR protected an approximately 30-bp region on both IRP1 and IRP2 from DNase I digestion. A 19-bp consensus DtxR-binding site was derived from a comparison of the various DtxR-regulated Operator/promoter sequences. Footprinting experiments using hydroxyl radicals and dimethyl sulfate demonstrated that DtxR interacted with these Operators in a symmetrical manner, probably as a dimer or multimer. The deduced amino acid sequence of an open reading frame (ORF1) located downstream from IRP1 was homologous with a family of periplasmic proteins involved in iron transport in gram-negative bacteria and with the ferrichrome receptor, FhuD, from Bacillus subtilis. These findings suggest that ORF1 encodes a membrane-associated lipoprotein that may serve as the receptor for a ferric-siderophore complex in C. diphtheriae.

  • the Operator early promoter Regions of shiga toxin bearing phage h 19b
    Molecular Microbiology, 2001
    Co-Authors: Ting Shi, David I Friedman
    Abstract:

    Summary Genes (stx ) encoding Shiga toxins (Stx), major virulence factors in some pathogenic strains of Escherichia coli (STEC), are located in prophages of the l family. Agents that induce prophages lead to high levels of Stx, suggesting a role for the prophage in stx expression. Activation of the phage regulatory cascade has been shown to contribute to Stx production and release. Therefore, repressor‐Operator interactions that maintain prophage repression appear important in regulating expression of a major bacterial virulence factor. To determine if the Operators of an stx-bearing phage have distinctive features, we characterized the Operator Regions of H-19B, a lambdoid phage carrying stx1 genes. H-19B mutants that grow in the presence of repressor (classically called virulent mutants) were selected and the mutations definitively identified the Operators. The H-19B Operators, as those in other lambdoid phages, comprise variations of an inverted repeat. Four repeats were identified in OR rather than the three found in each of the Operators of other lambdoid phages. Primer extensions identified the transcription start sites of PR and PRM, the two promoters in OR regulated by repressor.
