Significance of the presence of antibiotics on the microbial consortium in wastewater – The case of nitrofurantoin and furazolidone

• Nitrofurantoin and furazolidone had no adverse effect on the microbial consortium. The consortium behaviour degradation of antibiotics differed between drugs. NFT reduced organic carbon consumption increased EPS VOC production. FZD decomposition exceed 60% with a small reduction assimilation. was better represented by logistic mathematical model. Antibiotics in wastewater leads to migration pollutants disrupts natural processes mineralization matter. In order understand mechanism this, research undertaken influence nitrofurantoin (NFT) (FZD), microorganisms present model bioreactor. Our study confirmed biodegradation consortium, efficiency within 10 days 65% for FZD, but only 20% NFT. kinetic proved that presence analysed microbes, differ significantly reducing increasing production extracellular biopolymeric volatile compounds, assimilation other sources less extent, at expense cellular focus this antibiotic.
