Pullulan gum production from low-quality fig syrup using Aureobasidium pullulans / L.M. Marvdashti, A. Abdolshahi, S. Hedayati, M. Sharifi-Rad, M. Iriti, B. Salehi, J. Sharifi-Rad. - In: CELLULAR AND MOLECULAR BIOLOGY. - ISSN 0145-5680. - 64:8(2018), pp. 22-26. [10.14715/cmb/2018.64.8.4]
Abstract:
Pullulan is an important polysaccharide with several potential applications in food science, pharmaceutical and cosmetic industries, but high costs of pullulan production are the main limitation for commercial utilization. Therefore, a cost-effective process for pullulan production was developed using fig syrup as an exclusive nutrient source. In particular, the feasibility of using low quality fig syrup as a supplemental substrate for pullulan gum production by Aureobasidium pullulans was investigated. Fermentation was carried out over a range of fig syrup and sucrose degrees Brix (5-15%). Maximum pullulan gum production was observed after 96h using 12.5% fig syrup, yielding approximately14.06 g/L. This value of pullulan production (14.06 g/L) was higher than the amount of pullulan produced using sucrose as substrate (5.01 g/L). In conclusion, fig syrup was an effective substrate for pullulan production by Aureobasidium pullulans, and, therefore, this byproduct deserves attention for the cost-effective and environmentally friendly pullulan production.
