Microbial Composition and Variability of Natural Marine Planktonic and Biofouling Communities From the Bay of Bengal.

摘要: The Bay of Bengal (BoB) is the largest bay in world and presents a unique marine environment that subjected to severe weather, distinct hydrographic regime large anthropogenic footprint. Despite these features BoB's overall economic significance, this ecosystem its microbiome remain among most underexplored world. In study, amplicon-based microbial profiling was used assess bacterial, archaeal, micro-eukaryotic content unperturbed planktonic biofilm/biofouling communities within BoB. Planktonic were collected during Southwest monsoon season from surface (2 m), subsurface (75 deep-sea (1000 m) waters six south-central BoB locations compared concomitant mature biofouling photic-zone moorings (∼75 m). results demonstrated vertical stratification all with geographic variations disappearing environment. diversity found be driven by different members community, dominant phylotypes driving photic zone rarer species playing more influential role deep-sea. Geographic variability not observed co-located microbiomes, but community composition depth presence macro-fouling photosynthetic organisms. Overall, provide much needed baselines for longitudinal assessments can monitor health evolution dynamic critically important
