Lipopolysaccharide Architecture Dictates Susceptibility to Predation by Bdellovibrio bacteriovorus.

Disruption of LPS core biosynthesis in Escherichia coli significantly delays predation by four Bdellovibrio strains, with shorter LPS structures conferring greater resistance.

• Why it matters: Understanding how prey surface structures influence predation is crucial for leveraging predatory bacteria in controlling Gram-negative pathogens and managing microbial communities.
• What they did: Researchers systematically examined E. coli mutants with specific LPS truncations using four Bdellovibrio strains, assessing predation efficiency and surface interactions.
• The result: Findings reveal that LPS architecture modulates predation rates and predator activity, suggesting prey surface modifications could influence microbial predator-prey dynamics and potential biocontrol strategies.
