Antimicrobial secondary metabolites from marine gastropod egg capsules and egg masses.
Marine organisms have attracted special attention in the last three decades for their ability to produce interesting pharmacological active compounds. Even though all marine organisms have the potential to produce antimicrobial secondary metabolites, the gastropod has the vital sources of secondary metabolites particularly their egg capsule which has the promising antimicrobial secondary metabo...
متن کاملPhotosynthesis drives oxygen levels in macrophyte-associated gastropod egg masses.
Many aquatic animals deposit fertilized eggs in adherent clutches or gelatinous masses. Egg aggregation carries certain risks, including the potential for inadequate oxygen supply to embryos. Physical and biological conditions alter such risks. We examined the effects of light levels and associated photosynthetic organisms on the distribution of oxygen inside gelatinous egg masses of four tempe...
متن کاملAbility of Some Gastropod Egg Capsules to Protect against Low-salinity Stress
The ability of the egg capsules of three intertidal gastropod species to protect embryos against low-salinity stress was examined. Encapsulated embryos of Ilyanassa obsoleta (Say), Nucella lamellosa (Gmelin), and N. lima (Gmelin) were far more tolerant of transfer to water of reduced salinity than were embryos which had been prematurely removed from egg capsules and transferred to low-salinity ...
متن کاملSecondary metabolites from marine microorganisms.
After 40 years of intensive research, chemistry of marine natural products has become a mature field. Since 1995, there are signals of decreased interest in the search of new metabolites from traditional sources such as macroalgae and octocorals, and the number of annual reports on marine sponges stabilized. On the contrary, metabolites from microorganisms is a rapidly growing field, due, at le...
متن کاملShields against ultraviolet radiation: an additional protective role for the egg capsules of benthic marine gastropods
While structurally complex benthic egg capsules can lower the vulnerability of gastropod embryos to a variety of environmental risks, including predation, desiccation, osmotic shock, and bacterial attack, little is known about their ability to shield embryos from ultraviolet radiation (UV) I examined the exposure of benthic egg capsules of the marine intertidal gastropod Nucella emarginata to s...
