A promising protocol for achievement the accumulation rate of inulin compound in a suspension culture of Jerusalem artichoke (Helianthus tuberosus) was established. The effect of incorporated of cell cultures in combining with two type of biotic elicitors Aspergillus niger extract and Methyl-Jasmonate incorporation feeding medium on leaf cell growth patterns and production of inulin was investigated. The maximum value of cell growth parameters and highest content of inulinase activity (0.395 u/ml) were resulted from elicitation of augmented MS-medium with A. niger extract at the level of 0.2% in combination with Methyl-Jasmonate (150 μM) as compared with other concentrations after 2 weeks of cultivation. The chemical analyses of the different cell lines were spectro-photometerically performed. This study clearly indicates that combining of A. niger and Methyl-Jasmonate elicitors plays a critical role on inulin process and its accumulation in Jerusalem artichoke cell cultures.
