Metagenomic analysis on resistance genes in water and microplastics from a mariculture system

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1,   Pages 4-4 doi: 10.1007/s11783-021-1438-y

Abstract:

Microplastics existing widely in different matrices have been regarded as a reservoir for emerging contaminants. Mariculture systems have been observed to host microplastics and antibiotic resistance genes (ARGs). However, more information on proliferation of ARGs and metal resistance genes (MRGs) in mariculture system at the presence of microplastics is needed.
