Zusammenfassung:Bioactive peptides (BAPs) have been found to promote health through various mechanisms. Among them, antimicrobial peptides are gaining recognition as promising novel treatments. This study aims to generate BAPs from bovine colostrum whey using the proteolytic activity of Lactobacillus rhamnosus C25 and to evaluate their potential antibacterial efficacy, including their ability to synergistic efficacy against resistant bacteria. Bioactive peptides were successfully generated from lactobacillus culture proteases that were cultivated through batch fermentation. The resulting peptide fractions were then evaluated for their antibacterial efficacy against a selection of strains, including E. coli ATCC25922, S. aureus MTCC1144, Acinetobacter baumannii ATCC 17978, as well as clinically isolated resistant strains of E. coli (ESBL 1384), Acinetobacter 1379, and S. aureus (MRSA 1418). Notably, the peptide fractions with a molecular weight of
