Expression and regulation of the arsenic resistance operon of Acidiphilium multivorum AIU 301 plasmid pKW301 in Escherichia coli.
The arsenic resistance (ars) operon from plasmid pKW301 of Acidiphilium multivorum AIU 301 was cloned and sequenced. This DNA sequence contains five genes in the following order: arsR, arsD, arsA, arsB, arsC. The predicted amino acid sequences of all of the gene products are homologous to the amino acid sequences of the ars gene products of Escherichia coli plasmid R773 and IncN plasmid R46. Th...
متن کاملTransformation of Escherichia coli with a large plasmid of Acidiphilium multivorum AIU 301 encoding arsenic resistance.
Acidiphilium multivorum AIU 301 isolated from acid mineral water had strong arsenic resistance. This bacterium harbored a number of plasmids with different molecular sizes. A plasmid of 56 kbp, named pKW301, was isolated from A. multivorum AIU 301. When pKW301 was transferred into Escherichia coli JM109 by electroporation, an E. coli transformant carrying pKW301 exhibited resistance to sodium a...
متن کاملMetal resistance in Acidocella strains and plasmid-mediated transfer of this characteristic to Acidiphilium multivorum and Escherichia coli.
Acidophilic heterotrophic strain GS19h of the genus Acidocella exhibited extremely high resistance to CdSO4 and ZnSO4, with a MIC of 1 M for each. The respective MICs for an Acidocella aminolytica strain were 400 and 600 mM. The MICs of NiSO4 for the above strains were 200 and 175 mM, respectively. These strains were also resistant to CuSO4, the MICs being 20 and 40 mM, respectively. An Acidoce...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Today, efforts go towards the replacement of chemical surfactants by natural biological biosurfactants (biosurfactant), as these materials are not carcinogenic and highly compatibile with the environment. One of the main classes of biosurfactants is rhamnose containing glycolipid biosurfactant (rhamnolipids). This type of biosurfactants can be applied in many industries such as oil industry, ph...
