Wheat bran (WB), a byproduct of milling, is rich in bioactive compounds with significant health benefits. This study aimed to enhance the release of phenolic compounds, sugars, and organic acids from WB by integrating ultrasound (UsP) and microwave (MWP) pretreatments with solid-state fermentation (SSF). UsP and MWP disrupted WB cell walls, followed by SSF with Aspergillus niger. UsP increased total phenolic content by 21.30 % on day 1 of SSF. UsP and MWP boosted the availability of bound phenolic compounds like vanillic acid and dihydroxybenzoic acid. Both pretreatments enhanced antioxidant activity compared to untreated fermented WB, with peak activity on day 5 of fermentation at 1411 ± 5.156 μM Trolox/100 g DW for UsP WB and 291.6 ± 1.092 μM Trolox/100 g DW for MWP WB. This integrated approach improved the extraction efficiency of fermentable monosaccharides, particularly glucose and xylose, offering a sustainable bioprocessing strategy for WB valorization and supporting the circular bioeconomy.

This study investigates the phenolic compounds (PC), volatile compounds (VC), and fatty acids (FA) of extra virgin olive oil (EVOO) derived from the Turkish olive variety "Sarı Ulak", along with ADMET, DFT, molecular docking, and gene network analyses of significant molecules identified within the EVOO. Chromatographic methods (GC-FID, HPLC) were employed to characterize FA, PC, and VC profiles, while quality parameters, antioxidant activities (TAC, ABTS, DPPH) were assessed via spectrophotometry. The analysis revealed a complex composition of 40 volatile compounds, with estragole, 7-hydroxyheptene-1, and 3-methoxycinnamaldehyde as the primary components.
