Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Demonstration of nanofiltration‐based virus safety for AAV manufacturing using model viruses

Biotechnology Progress, EarlyView.
Abstract Virus safety for biopharmaceutical products has been a well‐established concern for several decades. While various virus reduction steps have been identified and implemented for traditional plasma‐derived and monoclonal antibody products, there are various challenges to achieving the same virus safety in emerging gene therapy products.
