Iron Biomineralization in the PoriferanIrcinia Oros

Journal of the Marine Biological Association of the United Kingdom, 1995
Iron-containing precipitates, present within the organic matrix of the poriferanIrcinia oroswere identified as crystalline lepidocrocite (γ-FeOOH) by electron diffraction and57Fe Mössbauer spectroscopy. The crystals were located specifically within the spongin filaments, suggesting that the binding and subsequent accumulation of iron by macromolecules ...

Chemical constituents of the marine sponge, Ircinia sp.

The brine shrimp lethality assay-directed fractionation of the dichloromethane extract from a marinc sponge Ircinia sp. led to the isolation of 3 linear furanoterpenes including, anhydrofurospongin-1, furodendin, and furospongolide, together with one methyl scalarane, 22-acetoxyl-16beta-hydroxy-24-methyl-24-oxoscalaran-25, 12beta-olactone.
