Predatory bacteria as potential biofilm control and eradication agents in the food industry
Biofilms are a major concern within the food industry since they have the potential to reduce productivity in situ (within the field), impact food stability and storage, and cause downstream food poisoning. Wi...

Compounds affecting predation by and viability of predatory bacteria
Bdellovibrio-and-like organisms (BALOs) are a small group of bacteria that actively predate on other Gram-negative bacterial species. Although viewed mostly in a positive light, such as their potential use as liv...

Open AccessCombined Application of Bacterial Predation and Violacein to Kill Polymicrobial Pathogenic Communities
Violacein is a bisindole antibiotic that is effective against Gram-positive bacteria while the bacterial predator, Bdellovibrio bacteriovorus HD100, predates on Gram-negative strains. In this study, we evaluated ...
