Although cellulose and hemicellulose, the major components of lignocellulose, are widely used in biofuel and chemical production, lignin, another predominant plant biomass component, remains underutilized. Chemical pretreatment methods for lignocellulose, such as mild alkali, can release cross-linked hydroxycinnamic acids such as ferulic acid, a precursor to various aroma compounds such as 4-vinyl guaiacol (4-VG), which has a clove-like aroma. To improve 4-VG production, an industrial strain of <em>Saccharomyces cerevisiae</em> Ethanol Red™ was engineered to express a novel phenolic acid decarboxylase (PDC) gene from <em>Rhodosporidium fluviale</em> LM-2, <em>Rf_</em>PDC_B. Mutant strain expressing <em>Rf</em>_PDC_B achieved 4-VG levels comparable to those reported in the literature after 48 h of fermentation using maize pericarp hydrolysate as the substrate, demonstrating efficient biotransformation of ferulic acid from lignocellulosic hydrolysates into 4-VG. In summary, a transformed cell line was created for the direct biocatalytic production of aromatic compounds from lignocellulosic hydrolysates.

Results showed that the average heating rates of HHAIB (4.73 %) and VSPB (4.84 %) were lower than those of HWB (6.99 %), but they were not significantly different. HHAIB effectively improved the ECG’s drying rate, flavonoid content, and color while reducing peroxidase activity, shrinkage, and hardness. In contrast, HWB and VSPB resulted in unfavorable nutrient loss and crumpling. Cell-wall polysaccharides and crystallinity properties analysis revealed that HHAIB induced deterioration of chelate-soluble pectin (CSP), Na₂CO₃-soluble pectin (NSP), and hemicellulose content, along with cellulose crystallinity. These changes in the molecular level led to disrupted cell wall stability, cell membrane permeability, and cell expansion pressure as well as increased porosity, which improved water diffusion, resulting in enhanced drying efficiency. However, over-blanching (&gt;50 °C) severely damaged structures which prolonged the drying process and formed an undesirable hollow structure.

Solubility studies of xanthone in ethanol-VCO mixtures were conducted at four temperatures (303.15–323.15 K) across eleven volume ratios (0:1–1:0). The results demonstrated that the mixed-solvent achieved superior xanthone solubility compared to pure ethanol or VCO, with the maximum solubility (0.0329 g/g) observed at a VCO mass fraction of 0.63 at 323.15 K. The Jouyban-Acree model was modified and successfully correlated the solubility data, achieving an R² value of 0.999. Applying this optimized solvent mixture in UAE, xanthone concentration increased by up to 12 % compared to VCO alone with α-mangostin reaching 83.167 mg/g MP, with a linear relationship observed between ultrasound intensity, extraction time, and xanthone yield. The kinetics of UAE were effectively modeled using Peleg’s model, the pseudo-second-order kinetic model type 2, and the Response Surface Method.
