Production of Inulinase by Free and Immobilized Cells of Penicillium funiculosum p.36

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 fermentatio...
