Survival strategy of Bdellovibrio

Abstract

The effects of cadmium and diuron, typical environmental pollutants, on the survival of predatory bacteria of the genus Bdellovibrio were studied. The adhesion and cohesion of bdellovibrios were shown to enhance cell resistance to xenobiotics. The viability of Bdellovibrio cells was shown to be higher at the stage of bdelloplasts. The obtained results confirm the concept of the surface-associated existence of Bdellovibrio in the natural environment and serve as a basis for the employment of predatory bacteria to solve the problems of public health, biological protection of ecosystems, and bioterrorism protection.
