| Resumen en inglés | The aim of this work was to optimize the growth conditions and continuous production of the enzyme using free and immobilized cells of inulinase by Penicillium funiculosum. The highest yield of enzyme (163.5U/mL) was obtained when the culture was incubated at 27oC and 200 rpm for 96h in a fermentation medium containing both inulin and peptone as sole carbon and nitrogen source, respectively. When the cells of the P. funiculosum were immobilized on different carriers, especially linen fibers, their production ability was successfully maintained for seven successive batches. When the fermentation was carried out using inulin juice prepared from Jerusalem artichoke tubers (in place of pure inulin), inulinase production could be sustained till the second cultivation batch of the P. funiculosum immobilized on linen fibers, yielding 122 U/mL enzyme. Results proved the feasibility of using crude inulin juice as a simple and economic carbon source for the production of inulinase |
