Pinctada margaritifera box from Viminacium [PDF]

open access: yesStarinar, 2017
A Pinctada margaritifera box was unearthed at Viminacium in 1985, at the site of Pe}ine, in a grave containing cremated remains. It was made from the shell of a pearl oyster (Pinctada margaritifera), an exotic clam whose habitat is tropical seas:

Assessment of an alternative Pinctada margaritifera spat collector in French Polynesia [PDF]

open access: yesAquaculture Reports, 2021
Plastic waste in the oceans is a growing concern due to its size diversity, its ubiquitous nature and its impact on both marine organisms and ecosystems. While threatened by this marine plastic litter, the aquaculture industries also represent one of its

Anisotropy of Mechanical Properties of Pinctada margaritifera Mollusk Shell [PDF]

open access: yesNanomaterials, 2020
The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. The compressive strength was evaluated through a uniaxial static compression test performed along the load directions ...

Transcriptome and proteome analysis of Pinctada margaritifera calcifying mantle and shell: focus on biomineralization [PDF]

open access: yesBMC Genomics, 2010
Background The shell of the pearl-producing bivalve Pinctada margaritifera is composed of an organic cell-free matrix that plays a key role in the dynamic process of biologically-controlled biomineralization.

HISTOLOGI JARINGAN MANTEL TIRAM (SAIBO) PADA BEBERAPA JENIS BIVALVIA SEBAGAI ALTERNATIF IMPLANTASI MUTIARA

open access: yesJurnal Pendidikan Matematika dan IPA, 2019
All types of bivalves have the potential to produce pearls. Pearls can be produced naturally and cultivated. In cultured pearls, pearl sac are obtained from saibo (slices of another bivalve mantle) that which come from pallial zone. This study wants know

Shell colors and microstructures of four pearl oyster species in the South China Sea

open access: yesAquaculture Reports, 2022
Wild marine pearl oyster shells have rich colors, and the color and gloss of pearls cultivated by pearl oysters are closely related to the pearl layer color of the mantle.

Phenome of pearl quality traits in the mollusc transplant model Pinctada margaritifera [PDF]

open access: yesScientific Reports, 2018
AbstractThe bivalve Pinctada margaritifera exhibits three main transplant phenotypes derived from the donor (from which a mantle graft tissue, the saibo, is excised), the recipient (into which the saibo is implanted with a nucleus, leading to the formation of a pearl sac “chimera”) and the cultured pearls themselves.
