Antimicrobial peptide antibiotics inhibit aerobic denitrification via affecting electron transportation and remolding carbon metabolism

Na Wang et al.

Summary: This study investigated the impact of polymyxin B (PMB) on aerobic denitrification performance. The results showed that PMB decreased nitrate removal efficiency and drove denitrifiers to transform more nitrate to biomass instead of producing gas-N. PMB also damaged bacterial membrane and suppressed key enzymes participating in denitrification and aerobic respiratory chains. In addition, denitrifiers exhibited different preferences for carbon sources in the presence of PMB.

Yu Zhang et al.

Summary: Research showed that biochar has a direct impact on cellular-level denitrification metabolism, with particularly strong stimulative effects seen in corn straw biochar produced at 500 degrees Celsius. This stimulating effect is mainly attributed to the bulk particles of corn straw biochar directly regulating carbon metabolism, promoting the use of produced reducing power for nitrogen reduction and subsequently reducing the accumulation of N2O.

Ionic copper strengthens the toxicity of tetrabromobisphenol A (TBBPA) to denitrification by decreasing substrate transport and electron transfer

Rui Wan et al.

Summary: This study investigated the combined effect of TBBPA and Cu on model denitrifying bacteria, finding that Cu intensified the toxicity of TBBPA to denitrification by stimulating EPS secretion, blocking glucose transport, suppressing key enzyme activity, and down-regulating gene expression related to electron transport. These effects led to decreased bacterial growth, insufficient electron donor, and lower electron transport activity, causing a synergistic toxic effect of TBBPA and Cu on denitrification. Overall, this study provides new insights into the combined impact of BFRs and HMs on microorganisms.
