Abstract Ammonia-oxidizing Archaea (AOA) are ubiquitous throughout the oceanic water column; however, our knowledge on their physiological and ecological diversity in different regions is rather limited. Here, we report cultivation characterization of two novel Nitrosopumilus strains, originating from coastal surface waters Northern Adriatic Sea. The combined genomic information revealed that each strain exhibits metabolic functional traits, potentially reflecting contrasting life modes....
Significance Circumstantial evidence indicates that especially deep-ocean heterotrophic microbes rely on particulate organic matter sinking through the oceanic water column and being solubilized to dissolved (DOM) prior utilization rather than direct uptake of vast pool DOM in deep ocean. Comparative metaproteomics allowed us elucidate vertical distribution abundance microbially mediated transport processes thus solutes throughout column. Taken together, our data suggest that, while...
Abstract Alkaline phosphatase (APase) is one of the marine enzymes used by oceanic microbes to obtain inorganic phosphorus (Pi) from dissolved organic overcome P-limitation. Marine APase generally recognized perform P-monoesterase activity. Here we integrated a biochemical characterization specific enzyme, examination global ocean databases, and field measurements, study type relevance promiscuity. We performed an in silico mining phoA homologs, followed de novo synthesis heterologous...
Zooplankton and microbes play a key role in the ocean's biological cycles by releasing consuming copious amounts of particulate dissolved organic matter. Additionally, zooplankton provide complex microhabitat rich inorganic nutrients which bacteria thrive. In this study, we assessed phylogenetic composition metabolic potential microbial communities associated with crustacean species collected North Atlantic. Using Illumina sequencing 16S rRNA gene, found significant differences between those...
To decipher the influence of depth stratification and surface provincialism on dark ocean prokaryotic community composition, we sampled major deep-water masses in eastern North Atlantic covering three biogeographic provinces. Their diversity was evaluated using ordination canonical analysis 454 pyrotag sequences. Variance partitioning suggested that 16% variation bacterial composition based while 9% due to geographic location. General linear mixed effect models showed subsurface waters...
The aim of this study was to compare the composition two deep-sea viral communities obtained from Romanche Fracture Zone in Atlantic Ocean (collected at 5200 m depth) and southwest Mediterranean Sea (from 2400 using a pyro-sequencing approach. results are based on 18.7% 6.9% sequences Sea, respectively, with hits genomes non-redundant RefSeq database. identifiable richness relative abundance both viromes were dominated by archaeal bacterial viruses accounting for 92.3% 83.6% Sea. Despite...

Polynucleobacter asymbioticus strain QLW-P1DMWA-1T represents a group of highly successful heterotrophic ultramicrobacteria that is frequently very abundant (up to 70% total bacterioplankton) in freshwater habitats across all seven continents. This was originally isolated from shallow Alpine pond characterized by rapid changes water temperature and elevated UV radiation due its location at an altitude 1300 m. To elucidate the strain's adjustment fluctuating environmental conditions, we...
Heterotrophic microbes inhabiting the dark ocean largely depend on settling of organic matter from sunlit ocean. However, this sinking materials is insufficient to cover their demand for energy and alternative sources such as chemoautotrophy have been proposed. Reduced sulfur compounds, thiosulfate, are a potential source both auto- heterotrophic marine prokaryotes.Seawater samples were collected Labrador Sea Water (LSW, ~ 2000 m depth) in North Atlantic incubated at situ temperature...
