Thaj Av Inhibitib nyhuv ntawm Sulphadimidine ntawm cov pab pawg microbial
Inhibition ntawm microbial kev ua ub ua no
Sulfamethoxine ncaj qha rau cov kab mob DNArs, RNA, thiab protein synthesis los ntawm kev thaiv cov neeg cov metabolism hauv cov metabolism hauv txoj kev. Kev tshawb fawb tau pom tias hauv Anaerobic ammonia oxidation systems, qhov denitricalfulation efficiency ntawm cov particle me me sludge (<0.5 mm) significantly decreases, and its nitrate reductase and nitrite reductase activities decrease, leading to a decrease in ammonia nitrogen removal rate. This inhibitory effect is directly related to microbial metabolic activity. Small particle sludge has high mass transfer efficiency and fast proliferation rate, but low microbial diversity makes it more susceptible to sulphadimidine stress.
Oxidative kev ntxhov siab thiab kev puas tsuaj ntawm tes
Sulfamethoxazine induces oxidative stress response in microorganisms, upregulating the expression of glutathione peroxidase genes (gpx), superoxide dismutase genes (SOD1/SOD2), and catalase genes (katE/katG). In the activated sludge system, exposure to sulphadimidine leads to an increase in the secretion of extracellular polymeric substances (EPS) by microorganisms, with a significant increase in protein and polysaccharide content, forming a protective barrier to reduce drug toxicity. However, high concentrations of sulphadimidine (>50 mg / l) tuaj yeem ua kev puas tsuaj ntawm tes membrane kev ntseeg siab, ua rau muaj kev xau ntawm cov tshuaj entracellular thiab tuag tes tuag.
