Phylogenetic Diversity of Bacteria Associated with the Marine Sponge Rhopaloeides odorabile
Determining the phylogenetic affiliation of sponge-associated microorganisms by 16S rRNA analysis facilitated the rational selection of culture media and isolation conditions to target specific groups of well-represented bacteria for laboratory culture. Expand
Population Dynamics of Chesapeake Bay Virioplankton: Total-Community Analysis by Pulsed-Field Gel Electrophoresis
It is concluded that, based on the dynamic nature of the Chesapeake Bay virioplankton community structure, the clonal diversity of bacterio- and phytoplankon host communities is an important component of the virus community. Expand
The culturable microbial community of the Great Barrier Reef sponge Rhopaloeides odorabile is dominated by an α-Proteobacterium
The location of strain NW001 within the sponge mesohyl was visualized by in situ hybridization, using fluorescently labeled probes based on the 16S rRNA gene sequence of this strain, suggesting that these bacteria may play a role in nutrient uptake by the sponge. Expand
Distribution of Vibrio vulnificus in the Chesapeake Bay.
The data demonstrate that V. vulnificus is a widespread and important component of the bacterial population of the Chesapeake Bay, with counts that are comparable to those reported from the Gulf of Mexico. Expand
Metamorphosis of broadcast spawning corals in response to bacteria isolated from crustose algae
Strain A3, a species of Pseudoalteromonas isolated from the CCA Hydrolithon onkodes (Heydrich), was able to induce significant levels of metamorphosis of Acropora willisae Veron & Wallace, 1984 and A. millepora larvae in laboratory assays, providing evidence for a widening range of morphogenic sources and demonstrates the role that micro- organisms may play in fine-scale coral recruitment.

Characterization of a Culturable Alphaproteobacterial Symbiont Common to Many Marine Sponges and Evidence for Vertical Transmission via Sponge Larvae
This is the first report of the successful culture of a bacterial symbiont of a sponge that is transferred through the gametes and densely associated with the larvae rather than being evenly distributed throughout the mesohyl. Expand
Diversity of aerobic and anaerobic ammonia-oxidizing bacteria in marine sponges
This work further supports the potential of sponge-associated microorganisms for nitrification and sheds light on anammox as a new aspect of the nitrogen cycle in marine sponges. Expand
Diversity and expression of nitrogen fixation genes in bacterial symbionts of marine sponges.
It is suggested that provision of fixed nitrogen is a means whereby symbionts benefit sponges in nutrient-limited reef environments that heretofore has been neglected and warrants further investigation. Expand
Distribution of viruses in the Chesapeake Bay.
The high virus counts obtained in this study suggest that viruses may be an important factor affecting bacterial populations in the Chesapeake Bay, with implications for gene transfer in natural aquatic bacterial populations and release of genetically engineered microorganisms to estuarine and coastal environments. Expand
Novel actinobacteria from marine sponges
Actinobacteria exclusively within the sub-class Acidimicrobidae were shown by 16S rDNA community analysis to be major components of the bacterial community associated with two sponge species in theExpand
