Bacterial carbon processing by generalist species in the coastal ocean
TLDR
The authors' direct measure of niche breadth for bacterial functional assemblages indicates that, in accordance with ecological theory, heterogeneity in the composition and supply of organic carbon to coastal oceans may favour generalist bacteria.

Transporter genes expressed by coastal bacterioplankton in response to dissolved organic carbon
TLDR
A highly resolved view of the potential for carbon flux into heterotrophic bacterioplankton cells identifies possible bioreactive components of the coastal DOC pool and highlights differing ecological roles in carbon turnover for the resident bacterial taxa.

Metagenomic Identification of Bacterioplankton Taxa and Pathways Involved in Microcystin Degradation in Lake Erie
TLDR
Genes for xenobiotic metabolism were overrepresented in microcystin-amended microcosms, suggesting they are important in bacterial degradation of microcyStin, a phenomenon that has been identified previously only in eukaryotic systems.

Microbial Community Response to Seawater Amendment in Low-Salinity Tidal Sediments
TLDR
Molecular approaches were used to evaluate the response of the prokaryotic community to controlled changes in porewater salinity levels in freshwater sediments from the Altamaha River, Georgia, USA, and found no significant differences were found between microbial community composition of control vs. seawater-amended treatments for either Bacterial or Archaeal members.

Bacterioplankton assemblages transforming dissolved organic compounds in coastal seawater.
TLDR
High-resolution clone libraries showed that the presence of members of OM60/241, OM185, SAR11, SAR86 and SAR116 in the HI populations indicated that members of these groups can assimilate the model DOC compounds, providing some of the first glimpses into heterotrophy byMembers of these poorly understood environmental clusters.

Algicidal Activity of Streptomyces eurocidicus JXJ-0089 Metabolites and Their Effects on Microcystis Physiology
TLDR
Tryptamine and tryptoline could potentially serve as more efficient and environmentally friendly alternative algicides than CuSO4 in controlling harmful cyanobacterial blooms.

Metatranscriptomic signature of exogenous polyamine utilization by coastal bacterioplankton.
TLDR
Taxonomic affiliation of significantly enriched diagnostic genes in the PUT and SPD libraries pointed to roseobacter- and SAR11-affiliated bacteria as the predominant taxa driving transformation in this coastal ocean, although other diverse marine bacterioplankton groups also contributed to polyamine-related gene transcription.

Flow-Cytometric Cell Sorting and Subsequent Molecular Analyses for Culture-Independent Identification of Bacterioplankton Involved in Dimethylsulfoniopropionate Transformations
TLDR
It is suggested that diverse bacterioplankton participate in the metabolism of DMSP in coastal marine systems and that their relative importance varies temporally.

Concentrations, turnover rates and fluxes of polyamines in coastal waters of the South Atlantic Bight
TLDR
Turnover rates and fluxes of polyamines decreased from near-shore waters to the shelf-break, following the pattern of chlorophyll a concentration, while fluxes into bacterioplankton were much lower than amino acid fluxes as a result of low ambient concentrations.
