Volatile-Mediated Inhibitory Activity of Rhizobacteria as a Result of Multiple Factors Interaction: The Case of Lysobacter capsici AZ78

Vlassi, A., Nesler, A., Parich, A., Puopolo, G., Schuhmacher, R.

INFORMATIVE ABSTRACT - A recent study showed that Lysobacter capsici AZ78 emits volatile organic compounds (VOCs) with toxic activity against soilborne plant pathogens when grown on a protein-rich medium.
Further investigations have been put in place on the volatile-mediated inhibitory activity of AZ78, specifically for a discrepancy between the quantity of pyrazines in the gaseous phase and the minimum quantity needed to achieve inhibition of plant pathogens already observed.
Besides VOCs, this new study showed that AZ78 bacterial cells produce ammonia in increased amounts. Ammonia production caused the alkalinization of the physically separated culture medium where Rhizoctonia solani was inoculated subsequently. This means that VOCs, ammonia and the growth medium alkalinization contribute to the overall inhibition activity of AZ78 against R. solani.

Based on these results, it is highly probable that the volatile-mediated inhibitory activity of rhizobacteriadepends on a multiple factors interaction.
