Inhibition of the predatory activity ofBdellovibrio by various environmental pollutants.
The predatory activity of bdellovibrios is affected by various environmental pollutants such as detergents, heavy metals, and pesticides. This was shown in a two-membered system ofBdellovibrio andPhotobacterium, in which the effect of the predator on the bioluminescence of the prey indicated the activity of the former. The high sensitivity of the bdellovibrios toward certain chemicals (e.g., CdCl2) indicates the possibility of using the system for biological monitoring of those chemicals.
