  • Extracellular lytic enzymes are used by biocontrol agents to attack plant-pathogen cell walls. A Gram-negative bacterial isolate named PG4 was selected as it showed high lipase, protease and chitinolytic activities in vitro. Analysis of its 16S rDNA sequence allocated PG4 to Lysobacter, and its 16S rRNA sequence clustered with the sequences of L. antibioticus and L. gummosus. At the same time, the Biolog Test was used to determine its physiological profile. PG4 was tested in vitro against a broad range of fungi and bacteria, and showed strong inhibitory activity that can be attributed to the production of diffusible antibiotic compounds. Antibiotic production was drastically reduced by growing PG4 on King’s B medium (KB) but was restored by the addition of Fe3+. Adhesion assays in 96-well polystyrene plates were used to evaluate biofilm production; the ability of PG4 to form biofilm was correlated with entry into stationary growth phase except when the bacterium was grown on KB. The strain was tested for the control of some fungal pathogens in vivo. The strong reduction of plant mortality confirmed the potential of Lysobacter sp. strain PG4 as a biological control agent.
