Research Abstract

In order to access the role of prokaryotes on organic matter fluxes, this study examined prokaryotic biomass, community composition, and its response to environmental changes (e.g., anthropogenic antibiotics contamination) in coastal marine environments. Results of this study showed that prokaryotes contribute a substantial portion of organic matter fluxes. In addition, the result showed that prokaryotic biomass, growth rate and community composition are drastically changed under environmental changes due to the anthropogenic antibiotics contamination
