Diplodia gossypina ATCC10936 produced chiral specific (+)-jasmonic acid (JA) that is the most biologically active form. (+)-JA is a plant growth hormone and also one of the most important aroma compounds responsible for jasmin-like aroma note. In order to develop a commercial bioprocess for the production of (+)-JA, optimal culture conditions for D. gossypina ATCC10936 were investigated. D. gossypina produced (+)-JA using either fructose and glucose as a sole carbon source. As a nitrogen source, $NaNO_3$ gave relatively high (+)-JA production. The optimal temperature for the production of (+)-JA by D. gossypina was $28^{\circ}C$, and optimal agitation was found to be 200 rpm. D. gossypina produced (+)-JA upto 600 mg/L in SM medium, although the highest level of biomass was obtained in PDMYS medium.
