Tissue-scale microbiota of the Mediterranean mussel (Mytilus galloprovincialis) and its relationship with the environment

摘要: In this study, we characterize the structural variation of microbiota Mytilus galloprovincialis at tissue scale, also exploring connection with microbial ecosystem surrounding water. Mussels were sampled within a farm located in North-Western Adriatic Sea and composition was analyzed gills, hemolymph, digestive glands, stomach foot by Next Generation Sequencing marker gene approach. showed distinctive structure, specific declinations level. Indeed, each is characterized distinct pattern dominant families, reflecting peculiar adaptation to respective niche. For instance, gland Ruminococcaceae Lachnospiraceae, being shaped ferment complex polysaccharides dietary origin into short-chain fatty acids, well matching general asset animal gut microbiota. Conversely, gill hemolymph ecosystems are dominated marine microorganisms aerobic oxidative metabolism, consistent role played these tissues as an interface external environment. Our findings highlight putative importance mussel for different aspects host physiology, ultimate repercussions on health productivity.
