Bacillus cereus-derived α-amylase disrupts biofilm formation and quorum sensing in multidrug-resistant Klebsiella pneumoniae

B. cereus-derived α-amylase exhibited potent anti-biofilm, antibacterial, and quorum-quenching activities against K. pneumoniae clinical isolates. These findings highlight its potential as a novel therapeutic agent for managing biofilm-associated infections, either alone or as an adjunct to conventional treatments.
