Pectinase Production from Banana Peel Biomass via the Optimization of the Solid-state Fermentation Conditions of Aspergillus niger Strain

In this study, the biomass of banana peel was used to produce pectinase via optimization solid-state fermentation conditions filamentous fungi Aspergillus nigeA. niger). The operating were optimized using method full factorial design with incubation temperature ranging between 25 °C and 35 °C, moisture content 40% 60%, inoculum size 1.6 x 106 spores/mL 1.4 107 spores/mL. Optimizing appeared crucial minimize sample in experimental determine significant correlation conditions. A relatively high maximal production 27 UmL-1 attained at 35° C incubation, 60% content, a low amount substrate (5 g). Given that other substrates (e.g., pineapple waste, lemon peel, cassava wheat bran) generally ranges 3 U/mL 16 (Abdullah et al., 2018; Handa 2016; Melnichuk 2020; Thangaratham Manimegalai, 2014; Salim 2017), thus yield derived from study (27 U/mL) considered moderately high. findings indicated would be potential for A. niger.
