Predation on bacterial pathogens by predatory bacteria of sewage origin: three days prey-predator interactions.

ABSTRACT:

Background

Predatory bacteria are Gram-negative microorganisms that grow within and lyse their bacterial prey. As bacterial predators have potential applications in medicine and biotechnology, the aim of this study was to isolate and identify predators from environmental samples. Therefore, three environmental bacteria belonging to the genus Bdellovibrio were isolated and characterized.

Results

The predator isolates tolerated pH range from 5 to 9 well, and were killed at pH ranges of 2 and 12. They survived best at 4 °C and 29 °C, tolerated to some extent -20 °C and even -80 °C, and were completely killed at 60° C. Furthermore, the host range analysis of the predator isolates was carried out on five Gram-negative (Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas a
