Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung Jan 2008

Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung

Kai F. Hung

Sulfate is a primary source of sulfur for most microbes and in some prokaryotes it is used an electron acceptor. The acidophile Ferroplasma acidarmanus (strain fer1) requires a minimum of 150 mM of a sulfate-containing salt for growth. Sulfate is assimilated by F. acidarmanus into proteins and reduced to form the volatile organic sulfur compounds methanethiol and dimethyldisulfide. In the absence of sulfate, cell death occurs by an unknown mechanism. In this study, cell viability and genomic DNA and ATP contents of F. acidarmanus were monitored in response to the absence of sulfate or the presence of sulfate and the …
