ABSTRACT
AIMS:
The control of Xanthomonas citri subsp. citri (X. citri), causal agent of citrus canker, relies heavily on integrated agricultural practices involving the use of copper-based chemicals. Considering the need for alternatives to control this disease and the potential of fungi from extreme environments as producers of bioactive metabolites, we isolated and identified a bioactive compound from Penicillium sp. CRM 1540 isolated from Antarctica marine sediment. METHODS ANDRESULTS:
The potential of compound as an antibacterial agent against X. citri was assessed through in vitro and greenhouse experiments. Molecular taxonomy indicates that this fungus is a possible new species of Penicillium. Results revealed 90% bacterial inhibition in vitro at 25 µg ml- 1 and a decrease in 75.37% of citrus canker symptoms emergency in vivo in treated leaves of Citrus sinensis (L.) Osbeck considering the number of lesions per cm2 (p < 0.05) in comparison with the control. The structure of the active agent was identified as penicillic acid based on a detailed spectroscopic analysis.CONCLUSION:
Penicillic acid can be an alternative against citrus canker. SIGNIFICANCE AND IMPACT OF STUDY Research into extremophile micro-organisms can identify molecules with biotechnological potential and alternatives to current agricultural practices.Palavras-chave
