    Exocellular Cyclic Dipeptides from a Ruegeria Strain Associated with Cell Cultures of Suberites domuncula (2004)
    Springer
    In:  Marine Biotechnology, 6 (1). pp. 95-103.
    Details
    Publication Date: 2015-08-26
    Description: From cell cultures of Suberites domuncula was isolated a bacterial strain, SDC-1, which was identified by 16S ribosomal RNA sequence analysis as an α-Proteobacterium of the genus Ruegeria. The occurrence of the strain in sponge cell culture could be explained by its resistance to the antibiotics used in the isolation of sponge cell cultures or by the preservation of SDC-1 by host sponge cells. The fatty acid composition of SDC-1 is characterized by branched C-12 methyl fatty acids. Two new and 8 known cyclic dipeptides were isolated and characterized from the fermentation broth of SDC-1. Cyclodipeptides are one of the families of cell-cell signaling compounds and may have some role to play in sponge-bacteria interactions.

    Cadmium, zinc and copper accumulation in the squid Illex argentinus from the Southwest Atlantic Ocean (2000)
    Springer
    In:  Marine Biology, 136 (6). pp. 1039-1044.
    Details
    Publication Date: 2021-06-28
    Description: The levels and burdens of Cd, Zn, Cu and Hg were measured in the dorsal mantle, digestive gland and gonads of the squid Illex argentinus, from the Southwest Atlantic Ocean. Mature and immature individuals of both sexes were analysed. Correlations of heavy metal concentrations and burdens with sex and food habits were studied. The highest metal levels were found, particularly for Cd, in the digestive gland, which attained a concentration of up to 270 μg g−1 (wet weight). Dorsal mantle and gonads exhibited the same order of metal enrichment: Zn〉Cu〉Cd. Zinc and Cu levels were higher in ovaries than in testes and varied with the stage of maturation. The dorsal mantle exhibited the lowest heavy metal concentrations. Mercury levels were below the detection limit of the method in all the tissues analysed.
