Transcriptome sequencing of Paracoccus denitrificans ATCC19367 with florfenicol exporsure

We report the application of transcriptome sequencing technology in florfenicol interfering with denitrification by Paracoccus denitrificans. More than 30 billion bases of sequences were obtained by sequencing analysis. We found 433 differentially expressed genes, of which 292 genes were down-regulated and 141 genes were up-regulated, respectively. Importantly, most of the denitrification genes were suppressed, which further led to the enrichment of key metabolic pathways. The weakening of protein synthesis was consistent with the bacteriostatic mechanism of florfenicol. In particular, we found 42 putative differentially expressed sRNAs. After homologous alignment, target gene prediction and functional analysis, it was proved that the sRNAs differential expression profile is likely to be a key transcription factor affected by antibiotics in denitrification. This study provides new ideas for further control of environmental antibiotic pollution. Overall design: Transcriptome detection of Paracoccus denitrificans ATCC19367 with or without florfenicol exporsure.
