Spatiotemporal dynamics of bacterial populations in the anoxic Cariaco Basin
Distributions of bacterial populations in the anoxic Cariaco Basin were studied over 2 yr (five cruises) at three stations using fluorescence in situ hybridization (FISH) and terminal restriction fragment length polymorphism (T-RFLP) of 16S ribosomal ribonucleic acid (rRNA) genes. FISH results demonstrate that the contribution of eproteobacterial abundances to total prokaryotic inventories was ...
متن کاملPrevalence of partnerships between bacteria and ciliates in oxygen-depleted marine water columns
Symbioses between Bacteria, Archaea, and Eukarya in deep-sea marine environments represent a means for eukaryotes to exploit otherwise inhospitable habitats. Such symbioses are abundant in many low-oxygen benthic marine environments, where the majority of microbial eukaryotes contain prokaryotic symbionts. Here, we present evidence suggesting that in certain oxygen-depleted marine water-column ...
متن کاملPhylogenetic diversity of bacterial and archaeal communities in the anoxic zone of the Cariaco Basin.
Microbial community samples were collected from the anoxic zone of the Cariaco Basin at depths of 320, 500, and 1,310 m on a November 1996 cruise and were used to construct 16S ribosomal DNA libraries. Of 60 nonchimeric sequences in the 320-m library, 56 belonged to the epsilon subdivision of the Proteobacteria (epsilon-Proteobacteria) and 53 were closely related to ectosymbionts of Rimicaris e...
متن کاملBiogenic nitrogen gas production at the oxic–anoxic interface in the Cariaco Basin, Venezuela
Excess nitrogen gas (Nxs 2 ) was measured in samples collected at six locations in the eastern and western sub-basins of the Cariaco Basin, Venezuela, in September 2008 (non-upwelling conditions) and March 2009 (upwelling conditions). During both sampling periods, Nxs 2 concentrations were below detection in surface waters, increasing to ∼ 22 μmol N kg−1 at the oxic–anoxic interface ([O2]<∼ 4 μ...
