Exploring the Composition and Functions of Plastic Microbiome Using Whole-Genome Sequencing.

摘要: Besides the ecotoxicological consequences of microplastics and associated chemicals, association microbes on plastics has greater environmental implications as may select for unique microbiome participating in environmentally significant functions. Despite this, functional potential with different types is understudied. Here, we investigate interaction between plastic marine biofilm-forming microorganisms through a whole-genome sequencing approach four incubated environment. Taxonomic analysis suggested that microplastic surfaces exhibit microbial profiles niche partitioning among substrates. In particular, abundance Vibrio alginolyticus campbellii pollution pose risk to food chain negatively impact aquaculture industries. Microbial genera involved xenobiotic compound degradation, carbon cycling, genes type IV secretion system, conjugal transfer protein TraG, plant-pathogen interaction, CusA/CzcA family heavy metal efflux proteins, TolC proteins were significantly enriched all substrates, indicating variety processes operated by plastic-microbiome. The present study gives detailed characterization rapidly altering composition gene pools adds new knowledge surrounding ramifications pollution.
