| Outline of Final Research Achievements |
Formation of high- and low-quality pearls has been one of the critical issues in Akoya pearl farming for many years. In this study, to confirm a recent report that bacterial inflammatory reactions cause deformation and blemishing in pearls, we performed several experiments to clarify the relationship between pearl quality and microflora of the nacreous layer around the pearl nucleus. The results of clone library analysis suggest that the microflora of the nacreous layer is related to the farming lot, not pearl quality.
