Abstract Modern conical microbialites are similar to some ancient stromatolites, but growth, behavior and diversity of cyanobacteria in modern remain poorly characterized. Here, we analyze the cyanobacterial 16S r RNA gene sequences from 14 ponds fed by four thermal sources Y ellowstone N ational P ark compare activity tips cones surrounding topographic lows (mats), respectively, high‐resolution mapping labeled carbon. Cones adjacent mats contain genetically distinct clusters filamentous,...
Dissimilatory sulphate reduction (DSR) leads to an overprint of the oxygen isotope composition by water. This is assumed occur via cell-internally formed sulphuroxy intermediates in pathway. Unlike sulphate, can readily exchange isotopes with Subsequent exchange, these intermediates, e.g. sulphite, are re-oxidised reversible enzymatic reactions thereby incorporating used for re-oxidation sulphur intermediates. Consequently, rate and expression DSR-mediated between water depend not only on...
The use of nucleic acid detection for HIV type 1 (HIV-1) is strongly recommended in infants <18 months age, whom serology unreliable. This study evaluated the Cobas AmpliPrep/Cobas TaqMan HIV-1 Qualitative Test v2.0 (TaqMan Qual Test, v2.0), a dual-target total real-time PCR assay. limit (LOD) new test plasma and dried blood spots (DBS) was determined with 2nd International RNA WHO standard. specificity assay tested EDTA (n = 1,301) DBS from HIV-negative adults 1,000). sensitivity using...
