Unveiling the cycle of dimethylsulfoniopropionate in the North Pacific Subtropical Gyre
A longstanding scientific enigma exists in oligotrophic subtropical waters: it appears that bacterial respiration contributes up to 90% of total community respiration even though the contribution of bacterial biomass to total biomass is much less. It has been suggested that experimental artifacts including pre-incubation filtration procedures, applied in order to separate bacteria from the rest...
متن کاملMicrobial community structure and function on sinking particles in the North Pacific Subtropical Gyre
Sinking particles mediate the transport of carbon and energy to the deep-sea, yet the specific microbes associated with sedimenting particles in the ocean's interior remain largely uncharacterized. In this study, we used particle interceptor traps (PITs) to assess the nature of particle-associated microbial communities collected at a variety of depths in the North Pacific Subtropical Gyre. Comp...
متن کاملEffect of visible light on dimethylsulfoniopropionate assimilation and conversion to dimethylsulfide in the North Pacific Subtropical Gyre
The aim of the present study was to assess the effect of photosynthetically active radiation (PAR, 400 to 700 nm) on the utilization of dissolved dimethylsulfoniopropionate (DMSPd) by microbial communities in the oligotrophic North Pacific Subtropical Gyre, using 35S-labeled substrate. Rates of DMSPd-sulfur (DMSPd-S) assimilation into macromolecules of microorganisms in surface mixed layer seaw...
متن کاملMicrobiome of Trichodesmium Colonies from the North Pacific Subtropical Gyre
Filamentous diazotrophic Cyanobacteria of the genus Trichodesmium, often found in colonial form, provide an important source of new nitrogen to tropical and subtropical marine ecosystems. Colonies are composed of several clades of Trichodesmium in association with a diverse community of bacterial and eukaryotic epibionts. We used high-throughput 16S rRNA and nifH gene sequencing, carbon (C) and...
