Antimicrobial compounds against bacterial diseases
Production of Lactobacillus plantarum TC92, an efficient antagonist of plant pathogenic bacteria
Biodegradable small synthetic antimicrobial peptides have proven to be effective against the three bacterial pathogens: Pseudomonas syringae pv. actinidiae (Psa); Xanthomonas fragariae (Xf), and X. arboricola pv. pruni (Xap). A number of selected strains of lactic acid bacteria isolated from fruit trees were effective in preventing infections by the bacterial pathogens. On the bases of preliminary toxicity tests these products are considered as safe.
In this project the first prototype formulations of two lead products; i.e. the antimicrobial peptide BP100 and the strains of Lactobacillus plantarum PM411 and TC92 have been prepared.

Control of bacterial pathogens
These products were tested against of the bacterial pathogens Xap, Psa and Xf, on respectively peach, kiwifruit and strawberry plants, under controlled environment greenhouse conditions. The effect of these products was similar to conventional antibiotics.
The next stages will be to scale-up the production, and to be tested under field conditions in orchards.
