Allantoin catabolism influences the production of antibiotics in Streptomyces coelicolor [PDF]

, 2014
Purines are a primary source of carbon and nitrogen in soil; however, their metabolism is poorly understood in Streptomyces. Using a combination of proteomics, metabolomics, and metabolic engineering, we characterized the allantoin pathway in ...

Host Cell Protein Challenges in Antibody Processing: Insights Into Persistence and Mitigation Strategies

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

Copaiba oleoresin as a substitute for sodium lasalocid in high‐concentrate diets for lambs: growth performance, ingestive behavior, and metabolic and ruminal parameters

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The indiscriminate and excessive use of ionophore additives has been associated with the emergence of multi‐resistant pathogenic strains and the global spread of antibiotic resistance, raising serious public health concerns. Thus, plant biocompounds have been the focus of several studies aiming to replace ionophore additives in ...
