Microplastics have significant influence on both freshwater cyanobacteria and marine microalgae, especially under co-exposure with other pollutants such as heavy metals, antibiotics, pharmaceuticals. In the present study, combined effects of microplastics (polyethylene terephthalate (PET) or polybutylene (PBT)) tetracycline hydrochloride (TCH) microalgae Closterium sp. were studied to evaluate their acute toxicity, cell density, total chlorophyll concentration, photosynthetic activity, antioxidant system, subcellular structure different treatments used explain physiological stress mechanism effects. The results indicate that single inhibition growth efficiencies (in terms density) 5.0%, 9.2%, 66.7%, 55.1%, 59.8% for PET (100 mg L-1), PBT TCH (10 PET/TCH (PET 100 L-1 10 PBT/TCH (PBT respectively, relative electron-transport rates (rETRs) 7.3%, 12.7%, 66.8%, 54.0%, 59.9%, each treatment compared control 7th day. Moreover, positive in alleviating toxicity toward sp., at same time, malondialdehyde level (MDA), superoxide dismutase (SOD) catalase (CAT) activity induced by much higher than those from microplastic but lower after 7 days. It was demonstrated causes a more serious oxidative PBT/TCH, groups could be attributed adsorption PBT. This work improves understanding

Antibiotic contamination has become an increasingly important environmental problem as a potentially hazardous emergent and recalcitrant pollutant that poses threats to human health. In this study, manganese peroxidase displayed on the outer membrane of Escherichia coli whole-cell biocatalyst (E. MnP) was expected degrade antibiotics. The activity 13.88 ± 0.25 U/L. typical tetracycline antibiotic chlortetracycline used analyze degradation process. Chlortetracycline at 50 mg/L effectively transformed via within 18 h. After six repeated batch reactions, retained 87.2 % initial over 87.46 enzyme after storage 25°C for 40 days. could be removed from pharmaceutical livestock wastewater by biocatalyst. Thus, efficient biocatalysts are effective alternatives degrading antibiotics have potential applications in treating contamination.
