Cascade Responses of Microbial Communities To Alcohols and Organic Acids in a Marine Microcosm Experiment.

ABSTRACT: Alcohols and organic acids are major energy-rich components of sewage, and marine environments are significant recipients of these pollutants. However, their effects on marine microbial communities remain poorly understood. Recent theoretical models suggest that high energy inputs can disrupt microbial networks that have evolved under energy-limited conditions. The aim of our study was to determine the community-level effects of two alcohols (ethanol and methanol) and two organic acids (acetate and succinate) using a marine microcosm time-series experiment. We tested three sediment types: one impacted by sewage, one by aquaculture, and one unimpacted. The tested concentrations were 0.05% and 0.5%. At 0.5%, we identified 469 sequence variants (determined from 16 S rRNA gene sequencing) with
