Embodiment Construction

[0042] In pearl culture, the production of pearls results from the deposition of nacre on the nuclei of inserted recipient oysters during the transplantation step. The procedure of transplanting nuclei often has a high failure rate due to poor healing or bacterial contamination of the incisions made by recipient oysters during transplantation. Consequently, the nuclei used in pearl culture are increasingly covered with a coating that reduces the failure rate of the implantation procedure.

[0043] Accordingly, the present invention relates to a nucleus covered or enveloped by a membrane comprising one or more exopolysaccharides (EPS).

[0044] The EPS membrane will have healing properties, enabling accelerated wound healing induced by the transplantation procedure, thus resulting in reduced mortality of recipient oysters leading to failure of the transplantation.

[0045]It has been demonstrated that some bacteria possess the ability to synthesize extracellular polymers, incl...

Abstract

The invention relates to a nucleus coated with a film comprising one or more exopolysaccharides (EPS) and optionally one or more bioactive molecules such as bactericidal or bacteriostatic agents, cicatrizing agents and / or anti-inflammatory agents, as well as to a method for obtaining said nucleus, in order to inhibit graft rejection in pearl oysters.

Description

technical field [0001] The present invention relates to the field of nuclei coating in pearl culture (Pearl oyster production of pearls). Therefore, the present invention relates to nuclei coated with a membrane having healing and antibacterial properties and capable of reducing the death and nuclei rejection phenomena caused by the insertion of said nuclei into recipient pinnacles. Background technique [0002] Pearl farming is a human activity consisting of the cultivation of mother-of-pearl oysters (Pinctada sp) in their natural environment to produce cultured pearls. The first step involves collecting and cultivating the pearl oysters, which will be used as donor oysters or recipient oysters. Transplantation consists of a surgical procedure in which the graft (part of the epithelium of the donor oyster mantle) (approximately 4mm 2 ) in combination with a nacre bead (nucleus) inserted into the pearl pouch of the recipient oyster. Once inserted into the recipient oyster...
