MALDI Yaklaşımı ile Bakteriyel Proteomik Profilleme Kullanılarak Süt Ürünlerinin Mikrobiyal Güvenliğinin Değerlendirilmesi

Overview

This study presents a protocol for rapid evaluation of microbial composition in dairy products, utilizing a combination of culturomics and MALDI-TOF MS for identification. The method achieves comparable taxonomy results to 16S rRNA sequencing but offers a faster turnaround time than traditional culture techniques.
