DOI : 10.4194/1303-2712-v18_1_22 Viewed : 351 - Downloaded : 248 The diversity of microbial communities associated with oysters within a commercial mariculture system was examined using molecular analysis of 16S rRNA Illumina sequencing. The aim of the study is to identify microbial diversity using molecular-based techniques, and compare the results obtained using three sampling points. Results showed, the microbial diversity associated with farmed oysters was dominated by Vibrio spp., Photobacterium spp., and Pseudoalteromons spp., while Psychrilyobacter spp., Prolixibacter spp., Cytophaga spp., Planococcus spp., and Exiguobacterium spp. were minor in abundance. These findings provide valuable information on the microbial community, demonstrating the microbial diversity in oysters and its major abundant species.
