Strain-Dependent Responses of Listeria monocytogenes Biofilms to Combined Enzymatic and Bacteriocin Treatments

Listeria monocytogenes forms resilient biofilms that protect cells from sanitizers and environmental stress, allowing the pathogen to persist in food processing environments. This study evaluated the combined effects of an engineered carbohydrate-active enzyme (CAase) and two food-grade bacteriocins, nisin and thermoph...

A Bioengineered Glycosyl Hydrolase Effectively Disrupts Campylobacter jejuni Biofilms

Results indicate that CAase effectively disrupts multiple components of C. jejuni biofilm architecture despite lacking direct antimicrobial activity, suggesting potential utility in poultry-processing or surface-sanitation applications where targeted enzymatic disruption could enhance cleaning efficacy.
