Abstract Background Bioaugmentation has the potential to enhance ability of ecological technology treat sulfonamide-containing wastewater, but low viability exogenous degraders limits their practical application. Understanding mechanism is important and optimize performance bioaugmentation, which requires a multifaceted analysis microbial communities. Here, DNA-stable isotope probing (DNA-SIP) metagenomic were conducted decipher bioaugmentation mechanisms in stabilization pond sediment microcosms inoculated with sulfamethoxazole (SMX)-degrading bacteria ( Pseudomonas sp. M2 or Paenarthrobacter R1). Results The both strains R1, especially strain significantly improved biodegradation rate SMX, its capacity was sustainable within certain cycle (subjected three repeated SMX additions). removal strategy using degrading also abated accumulation transmission risk antibiotic resistance genes (ARGs). Strain inoculation lowered bacterial diversity altered community, while R1 had slight effect on community closely associated indigenous microorganisms. identified as primary SMX-assimilating systems based DNA-SIP analysis. Combining genomic information pure culture evidence, enhanced by directly participating degradation, did it degradation stimulating SMX-degrading activity microorganisms ) community. Conclusions Our findings demonstrate that feasible for clean-up terms efficiency ARG transmission, well impact advantage highlighted.

Strain-level diversity in sulfonamide biodegradation: adaptation of Paenarthrobacter to sulfonamides

The ISME Journal, Год журнала: 2024, Номер 18(1)

Опубликована: Янв. 1, 2024

The widespread occurrence of sulfonamides raises significant concerns about the evolution and spread antibiotic resistance genes. Biodegradation represents not only a mechanism but also clean-up strategy. Meanwhile, dynamic diverse environments could influence cellular function individual sulfonamide-degrading strains. Here, we present Paenarthrobacter from different origins that demonstrated growth patterns abilities. Generally, degradation performance was largely associated with number sadA gene copies relied on its genotype. Based survey sad genes in public database, an independent mobilization transposon-borne between chromosome plasmid observed. Insertions multiple greatly enhance performance. Moreover, cluster transposable element showed phylogenetic conservation currently, being identified two genera (Micrococcaceae) Microbacterium (Microbacteriaceae). exhibited high capacity for genome editing to adapt specific environmental niche, opening up new opportunities bioremediation applications.
