The present study investigated the performance of a self-made nanofiltration (NF) membrane for the removal of antibiotics from wastewater under changing operating conditions such as pH, initial feed concentration, operating pressure, and temperature. Amoxicillin (AMX) was used as one of the commonly prescribed antibiotics. A self-made NF membrane containing Polyethersulfone (PES), and Polyvinyl...

A sensitive ELISA was developed for the detection of amoxicillin (AMX) in serum, urine, and milk. The ELISA used an indirect competitive method produced by coating the plate with ovalbumin conjugated with AMX hapten. Antibodies against AMX-BSA were detected by a goat-antirabbit antibody conjugated with peroxidase. Calibration standard curves ranged from 1.28 ng/mL to 20 microg/mL [IC(50) (inhib...

This model-based study investigated the mechanisms and operational window for efficient repression of nitrite oxidizing bacteria (NOB) in an autotrophic nitrogen removal process. The operation of a continuous single-stage granular sludge process was simulated for nitrogen removal from pretreated sewage at 10 °C. The effects of the residual ammonium concentration were explicitly analyzed with th...

A spectrophotometric method using flow injection analysis (FIA) is described for the determination of amoxicillin (AMX). Its detection limit, linearity and reproducibility were examined.The automated method is based on a coupling reaction between AMX and diazotized paranitroaniline (DPNA) in alkaline medium to form an intense reddishorange, water-soluble dye that is stable and has a maximum abs...

The effects of co-amoxiclav (AMC) and amoxicillin (AMX) therapy on the nasopharyngeal flora of children with acute otitis media (AOM) were compared. Nasopharyngeal culture for aerobic and anaerobic bacteria were obtained before therapy and 2-4 days after completion of antimicrobial therapy in 25 patients treated with either antibiotic. After therapy, 16 (64%) of the 25 patients treated with AMX...

A strictly aerobic, mesophilic bacterium, strain AMX 51(T), was isolated from anaerobic digester sludge. Cells were Gram-negative, motile, non-sporulating, straight to curved rods with one polar flagellum. The isolate had phenotypic traits of the genus Bosea, including cellular fatty acid and substrate utilization profiles. Physiological characteristics and antibiotic susceptibility were determ...
