Evaluation of antimicrobial and antifungal activity of hydroethanolic extracts of in vitro and ex vitro seedlings of Dionaea muscipula J. Ellis

Resumen

Objective: To evaluate the antibacterial and antifungal activity of hydroethanolic extracts of Dionaea muscipula J. Ellis against bacteria models and fungi of agricultural importance.

Design/Methodology/Approach: In vitro plants of D. muscipula were propagated and acclimatized for three months. The antibacterial activity of the hydroethanolic extracts against Escherichia coli and Bacillus cereus was evaluated, and the antifungal activity against Aspergillus niger, Fusarium oxysporum and Pseudocercospora fijiensis. Analysis of variance (ANOVA) was carried out to compare the means obtained with Tukey’s test (p≤0.05).

Results: The hydroethanolic extracts of in vitro and acclimatized D. muscipula presented bacteriostatic activity against the bacteria E. coli (65.20 and 69.78 % of inhibition) and B. cereus (91.75 and 92.61 % of inhibition), and antifungal activity against the fungus P. fijiensis of 7.56 and 14.21 % of inhibition, respectively.

Study Limitations/Implications: The hydroethanolic extracts of in vitro and acclimatized D. muscipula did not show antifungal activity against A. niger and F. oxysporum.

Findings/Conclusions: The hydroethanolic extracts of in vitro and acclimatized D. muscipula presented bacteriostatic activity against bacteria E. coli and B. cereus and antifungal activity against the fungus P. fijiensis.
