Natural Assemblages of Marine Proteobacteria and Members of the Cytophaga-Flavobacter Cluster Consuming Low- and High-Molecular-Weight Dissolved Organic Matter
ABSTRACT We used a method that combines microautoradiography with hybridization of fluorescent rRNA-targeted oligonucleotide probes to whole cells (MICRO-FISH) to test the hypothesis that theExpand
Contribution of major bacterial groups to bacterial biomass production (thymidine and leucine incorporation) in the Delaware estuary
Assimilation of 3HH-thymidine and 3HH-leucine was examined at the single-cell level using a combination of microautoradiography and fluorescent in situ hybridization (Micro-FISH) to determine theExpand
Contribution of SAR11 Bacteria to Dissolved Dimethylsulfoniopropionate and Amino Acid Uptake in the North Atlantic Ocean
ABSTRACT SAR11 bacteria are abundant in marine environments, often accounting for 35% of total prokaryotes in the surface ocean, but little is known about their involvement in marine biogeochemicalExpand
Wide-spread occurrence and clonal variation in viruses which cause lysis of a cosmopolitan, eukaryotic marine phytoplankter Micromonas pusilla
Seven clonal isolates of viruses which cause lysis of the eukaryotic, naked, photosynthetic flagellate Micrornonas pusilla (Prasinophyceae) were isolated from the coastal waters of New York, Texas,Expand
The GAAS Metagenomic Tool and Its Estimations of Viral and Microbial Average Genome Size in Four Major Biomes
We present Genome relative Abundance and Average Size (GAAS), a complete software package that provides improved estimates of community composition and average genome length for metagenomes in both textual and graphical formats. Expand
The structure of bacterial communities in the western Arctic Ocean as revealed by pyrosequencing of 16S rRNA genes.
Bacterial communities in the surface layer of the oceans consist of a few abundant phylotypes and many rare ones, most with unknown ecological functions and unclear roles in biogeochemical processes.Expand
Standing stocks, production, and respiration of phytoplankton and heterotrophic bacteria in the western Arctic Ocean
Abstract Standing stocks and production rates for phytoplankton and heterotrophic bacteria were examined during four expeditions in the western Arctic Ocean (Chukchi Sea and Canada Basin) in theExpand
Biogeography of major bacterial groups in the Delaware Estuary
We used fluorescence in situ hybridization to examine the spatial and temporal variation in the abundance of major bacterial groups in the Delaware Estuary. The abundance of alpha- andExpand
Aerobic Anoxygenic Phototrophic Bacteria in the Mid-Atlantic Bight and the North Pacific Gyre
ABSTRACT The abundance of aerobic anoxygenic phototrophic (AAP) bacteria, cyanobacteria, and heterotrophs was examined in the Mid-Atlantic Bight and the central North Pacific Gyre using infraredExpand
Infection of phytoplankton by viruses and reduction of primary productivity
NATURAL marine waters contain roughly 106 to 109 virus particles per ml, yet their role in aquatic ecosystems and the organisms that they infect remain largely unknown. Electron microscopy has beenExpand
