Microbiological evaluation is one of the most important parameters for analyzing the viability of an oyster farming system, which addresses public health and ecological concerns. Here, the microbiological quality of the oyster Crassostrea rhizophorae cultivated in a monitored environment and from natural beds in Bahia, northeastern Brazil, was determined. Bacterial diversity in oysters was meas...

In addition to supporting a harvest, the eastern oyster (Crassostrea virginica) in Chesapeake Bay provides ecosystem services such as removing seston, enhancing water clarity and creating benthic habitat. Our objective was to create a flexible ecosystem-based decisionmaking tool to support oyster restoration and management. This Oyster Restoration Optimization model (ORO) incorporates predictio...

Oyster reefs and seagrass beds are being lost worldwide at alarming rates. These habitats provide many services to humankind and, thus,much effort has been dedicated to their restoration. Here, we examine the efficacy of created oyster reefs at enhancing seagrass beds through the amelioration of hydrographic conditions and water quality. We carried out a field experiment in the Northern Gulf of...

OmpU porins are increasingly recognized as key determinants of pathogenic host Vibrio interactions. Although mechanisms remain incompletely understood, various species, including the human pathogen Vibrio cholera, require OmpU for host colonization and virulence. We have shown previously that OmpU is essential for virulence in the oyster pathogen Vibrio splendidus LGP32. Here, we showed that V....

We conducted a preliminary investigation of wastewater treatment efficiency and economic cost of the oyster-shell-bedded constructed wetlands (CWs) compared to the conventional gravel-bedded CW based on field monitoring data of water quality and numerical modeling. Four study subsurface (SSF) CWs were built to receive wastewater from Taipei, Taiwan. Among these sites, two are vertical wetlands,...

Oysters are economically and ecologically important bivalves, with its calcareous shell and delicious meat. The shell composition is a blend of inorganic crystals and shell proteins that form an organic matrix which protects the soft inner tissue of the oyster. The objective of the study was to compare the composition of organic matrix proteins (OMP) of two phylogenetically related species: the...

Oysters are bivalve molluscs in the family Osteridae of the order Ostereoida and are found throughout the world. Quality of stored muscle of oyster, Crossostrea glomerata depends on the temperature and storage time. Investigation on factors responsible for spoilage of oyster meat in refrigerator (7±2°C); in term of biochemical indices, indicated that in 1-2 days the following changes will accur...

Draft genome sequences of oyster-associated Pseudomonas stutzeri strain MF28, P. alcaligenes strain OT69, P. aeruginosa strain WC55, Stenotrophomonas maltophilia strain MF89, and Microbacterium maritypicum strain MF109 are reported. Genome-wide surveys of these isolates suggest that the oyster microbiome, which remains largely understudied, has a strong potential to degrade crude oil.

This is the first study analyzing Pacific oyster microbiota in the Puget Sound estuarine system using a next-generation sequencing method. Taxonomic analysis indicated that Tenericutes, Chlamydiae, Proteobacteria, and Firmicutes were the most abundant phyla. Small numbers of operational taxonomic units (OTUs) belonging to the Vibrio genus were detected in all the oyster microbiome samples.
