Jasmonic acid production via liquid fermentation with Botryodiplodia theobromae strains natives to southeast mexico. Agrociencia [online]. 2017, vol.51, n.8, pp.885-893. ISSN 2521-9766.

Jasmonic acid (JA) is an endogenous plant growth-regulating hormone found in plant species. It is involved in functions such as senescence and resistance. Plants produce these after damage due to pathogenic microorganisms or insects. An alternative for its production is to use microorganisms, the most used is Botryodiplodia theobromae. The objective of our study was to evaluate the JA production via liquid fermentation with B. theobromae strains, isolated from tropical areas of southeastern Mexico. The experimental design was completely random; the evaluated variable was the JA production capacity for each strain. The data were analyzed with the ANDEVA, and the means compared by the Tukey test (p≤0.05), for which we used the SAS statistical software. Likewise, we developed a kinetic production study with the most JA producing strain through pH, substrate consumption, biomass, and JA production. Twenty B. theobromae strains were isolated from cocoa (Theobroma cacao L.), passion fruit (Passiflora edulis L.), mango (Mangifera indica L.), coconut (Cocos nucifera L.) and papaya (Carica papaya L.) in experimental fields at Veracruz and Tabasco, Mexico. Five of these strains produced JA. Metabolites started to be produced from day ten of the bioreaction. Thus, we show that the phytopathogenic fungus of tropic B. theobromae can produce JA in a liquid fermentation system.
