Effects of substratum type on bacterial community structure in biofilms in relation to settlement of plantigrades of the mussel Mytilus coruscus

摘要: Abstract In this study, Illumina MiSeq sequencing was used to characterize the bacterial communities in biofilms that formed on different substratum types including glass, steel, acrylic and hydrophobic glass. The link between community structure plantigrade settlement of mussel Mytilus coruscus explored. preference plantigrades for non-biofilmed substrata also examined. High-throughput revealed varied substrata. overwhelming majority sequences (>80% all sequences) belonged only three phyla: Proteobacteria, Bacteroidetes Firmicutes. phylum Proteobacteria dominating group biofilm samples. Cluster analysis based Bray–Curtis distances showed glass samples differed from those other densities developed were higher than present results percentage steel variation might lead differences activity. There no selective choice plantigrades. Thus, type affected cell bacteria biofilms, which differentially attractive M. coruscus.
