Flower Garden Banks National Marine Sanctuary: Antimicrobial Properties of Bacteria Associated with the Boulder Star Coral, Montastrea faveolata

Overview Corals have been shown to harbor unique microbial communities associated with their surface mucopolysaccharide layer, which is hypothesized to play an important role in defense against invading pathogens (Ritchie and Smith, 2004). In this study, bacterial associates of Montastraea faveolata surface mucus were compared between the healthy, disease-free reefs of the Flower Garden Banks N...

Aspartic proteinases in the digestive tract of marine decapod crustaceans.

Decapod crustaceans synthesize highly active proteolytic enzymes in the midgut gland and release at least a part of them into the stomach where they facilitate the first step in peptide hydrolysis. The most common proteinases in the gastric fluid characterized so far are serine proteinases, that is, trypsin and chymotrypsin. These enzymes show highest activities at neutral or slightly alkaline ...

Patterns of Water and Solute Regulation in the Muscle Fibres of Osmo- Conforming Marine Decapod Crustaceans

1. The patterns of myoplasmic water and solute regulation were examined in several species of marine decapod crustaceans acclimated to various salinities. Three osmoconformers (Callianassa cahformemsis, Cancer antennarius, Emerita analoga) and one weak osmoregulator {Pachygrapsus crassipes) were studied. 2. Although haemolymph water and solute activities varied with adaptational salinity in the...
