Biogenic reefs formed by dense aggregations of the eastern oyster Crassostrea virginica are a dominant feature in most estuarine systems along the Atlantic and Gulf of Mexico. Oyster reefs are complex in their structural nature and have long been recognized for their potential habitat value. However, relatively few studies have characterized nekton abundance in this complex habitat type, and li...

Oyster extracts have been reported to have many bioactive peptides. But the function of oyster peptides produced by proteolysis is still unknown. In this study, the oligopeptide-enriched hydrolysates from oyster (Crassostrea gigas) were produced using the protease from Bacillus sp. SM98011 at laboratory level, and scaled up to pilot (100 L) and plant (1,000 L) levels with the same conditions. A...

Oysters (Crassostrea virginica) were a central component of the Chesapeake Bay ecosystem in 1607 when European settlers established Jamestown, VA, the first permanent English settlement in North America. These estuarine bivalves were an important food resource during the early years of the James Fort (Jamestown) settlement while the colonists were struggling to survive in the face of inadequate...

A compressive description of tropical milky white mushroom (Calocybe indica P&C var. APK2) is provided in this review. This mushroom variety was first identified in the eastern Indian state of West Bengal and can be cultivated on a wide variety of substrates, at a high temperature range (30~38℃). However, no commercial cultivation was made until 1998. Krishnamoorthy 1997 rediscovered the fungus...

This study was conducted to determine the presence of hepatitis A virus (HAV) in raw oysters (Crassostrea belcheri) using a virus concentration method and reverse transcription-nested polymerase chain reaction (RT-nested PCR). A total of 220 oyster samples were collected from oyster farms and local markets in Thailand. HAV was found in three oyster samples. Nested PCR products of HAV detected i...

Norwalk-like viruses (NLVs), or small round structured viruses, are known to cause acute gastroenteritis associated with eating contaminated shellfish. Between 1993 and 1996, three oyster-related gastroenteritis outbreaks attributed to NLV occurred in Louisiana. Intensive trace-back and environmental investigations revealed that the overboard disposal of sewage by oyster harvesters into oyster-...

Oyster (Crassostrea gigas) is one of the important aquatic resources for Japanese, and it has a long history as food. In terms of the quantity of production, Japan is the third, following China and Korea [1]. As the oyster meat contains a plenty of nutrient components, it has been utilized as the health food in addition to food. Peptides contained in oyster meat extract powder have been paid at...

The Eastern oyster, Crassostrea virginica, has historically supported a major fishery along the Atlantic and Gulf coasts of North America. Although commercial landings of oysters along the East Coast have been in significant decline for decades, oyster aquaculture has the potential to provide for a sustained commercial harvest as well as to generate a product that is superior to wild-caught oys...
