Scallop shells as biosorbents for water remediation from heavy metals: Contributions and mechanism of shell components in the adsorption of cadmium from aqueous matrix

Heliyon, Journal Year: 2024, Volume and Issue: 10(7), P. e29296 - e29296

Published: April 1, 2024

To ascertain their potential for heavy metal pollution remedy, we studied the adsorption mechanism of cadmium onto scallop shells and interactions between shell matrix. Intact were used to investigate uptake diffusion contaminant carbonatic layers, as well evaluate distribution major trace elements in LA-ICPMS measurements demonstrate that Cd is adsorbed on a very thin layer inner outer surfaces shell. Structural thermal analyses showed presence 9 wt.-% CdCO

Identification of Shell Colour Pigments in Marine Snails Clanculus pharaonius and C. margaritarius (Trochoidea; Gastropoda)

PLoS ONE, Journal Year: 2016, Volume and Issue: 11(7), P. e0156664 - e0156664

Colour and pattern are key traits with important roles in camouflage, warning attraction. Ideally, order to begin understand the evolution ecology of colour nature, it is identify and, where possible, fully characterise pigments using biochemical methods. The phylum Mollusca includes some most beautiful exemplars biological pigmentation, vivid colours sea shells particularly prized by collectors scientists alike. Biochemical studies molluscan shell were fairly common last century, but few these have been confirmed modern methods very characterised. Here, we use chemical multi-modal spectroscopic techniques two porphyrin eumelanin marine snails Clanculus pharaonius C margaritarius. same porphyrins also identified coloured foot tissue both species. We high performance liquid chromatography (HPLC) show definitively that uroporphyrin I III. Evidence from confocal microscopy analyses shows distribution corresponds striking pink-red C. shells, as well dots lines on early whorls margaritarius yellow-brown later whorls. Additional HPLC results suggest likely responsible for black spots. refer differently trochopuniceus (pink-red) trochoxouthos (yellow-brown) distinguish between them. Trochopuniceus not found a third species superfamily, Calliostoma zizyphinum, despite its superficially similar colouration, suggesting this has different pigments. These findings implications study molluscs specifically, other taxa more generally, since homology visible cannot be assumed without identification

Abstract Very little is known about the evolution of molluskan shell pigments, although Mollusca a highly diverse, species rich, and ecologically important group animals comprised many brightly colored taxa. The marine snail genus Clanculus was chosen as an exceptional model for studying color, first, because in margaritarius pharaonius both foot share similar colors patterns; second, recent studies have identified trochopuniceus (pink‐red), trochoxouthos (yellow‐brown), uroporphyrin I III , tissue these species. These unusual characteristics provide rare opportunity to identify genes involved color production because, same pigments occur tissue, color‐related may be simultaneously expressed mantle (which produces shell) tissue. In this study, transcriptomes two along with third species, Calliostoma zizyphinum were sequenced associated synthesis porphyrins. selected negative control not found As expected, necessary all three but gene expression levels consistent uroporphyrins only . results are relevant understanding pigmentation also other pigmentation, including (mainly marine) mollusks soft tissues shells, annelid platyhelminth worms, some bird feathers.
