Résumé:

This study presents the development of a sophisticated liquid chromatography-mass spectrometry approach leveraging hydrophilic interaction chromatography (HILIC) for the quantification of kanamycin and spectinomycin in fermentation media. The method was validated per International Council for Harmonisation guidelines, demonstrating robust linearity, precision, and accuracy. To mitigate pronounced matrix effects common to complex fermentation matrices, sample preparation was thoroughly optimized with solid-phase extraction employing MCX sorbent, thereby enhancing recovery rates and minimizing analytical interference. The validated protocol demonstrated high correlation coefficients (R > 0.998), underscoring its robustness and reliability for the accurate quantification of antibiotics in challenging bioprocess environments, providing a valuable analytical tool for bioreactor system monitoring.

Résumé:

We evaluated a method to localize disulfide bonds in bovine pancreatic ribonuclease (RNase) by applying low pH trypsin protein digestion with a bottom-up LC-ESI-QTOF-MS approach. The goal was to minimize disulfide bond scrambling during sample preparation. By using N-ethylmaleimide (NEM) for alkylation of free cysteines, we achieved 92% sequence coverage and successfully identified the native disulfide bonds between specific cysteine residues. However, scrambled disulfide bonds were also observed. Our results indicate that while this low pH digestion method helps preserve native disulfide bonds, further refinement is needed to fully prevent disulfide bond rearrangement during sample preparation.
