Special Issue Information

Dear Colleagues,

Lignocellulosic biomass represents the most abundant, renewable, globally available, and potent resource for producing valuable products such as biofuels, bioactive compounds, and biomaterials through fermentation. Virtually anything presently derived from oil can be sourced from lignocellulosic biomass. The challenge for researchers lies in developing innovative, environmentally friendly methods and technologies for fractionating and converting cellulose, hemicellulose, and lignin from agricultural residues, forestry wastes, dedicated energy crops, and various other lignocellulose-containing waste materials into sustainable and commercially viable products. Technologies enabling the fermentation of lignocellulosic biomass play a crucial role in minimizing carbon emissions and fostering the development of a circular bioeconomy.

The aim of the Special Issue, titled "Lignocellulosic Biomass Valorization", is to showcase innovative research and advancements in sustainable fermentation-based technologies for converting lignocellulosic biomass into high-value-added and novel products.

The scope of this Special Issue includes, but is not limited to, the following:

  1. Technological innovations in the pretreatment and processing of lignocellulosic biomass to enhance the bioavailability of cellulose, hemicellulose, and lignin;
  2. Development of novel approaches in fermentation technology to improve product yield and biomass conversion efficiency;
  3. Pathways and processes for developing novel bio-based products through the microbiological transformation of lignocellulosic biomass;
  4. Economic analyses evaluating the economic viability and environmental impact of fermentation technologies for biomass valorization.

Abstract: The production of ethanol from wastes resulting from the process of growing Amazonian fruit is a little-explored approach, in which unknown chemical compounds are released with potential for industrial application. This work aimed to produce lignocellulosic ethanol from waste from Amazonian fruit farming and to chemically characterize the stages of the process. The wastes (açaí seeds, mango peel, and peach palm peel) were pretreated with 1% to 5% H2SO4 and 15% solids; the resulting solid fraction was enzymatically hydrolyzed with cellulase at 20 FPU, and the liquid fraction (liqueurs) and enzymatic and fermented hydrolysates produced were chemically characterized. Via HPLC for sugars and fermentation inhibitors, we determined the antioxidant capacities and total phenolic compounds. The liquors from the pretreatment of açaí seeds released the most significant amount of glucose, while in the hydrolyzed solid fractions, the mango peel produced the highest glucose content. Among the fermented liquors, the highest ethanol content was the açaí seed at 15 and 5% (0.183–0.276 g/L). High glucose levels were produced (0.09–25.05 g/L) and provided ethanol levels that can be improved (0.061–10.62 g/L), in addition to liquors and hydrolysates with interesting amounts of phenolic compounds (14.04–131.87 mg EAG/g DM) and high antioxidant capacities (417.78–2774.07 mmol TEAC/g), demonstrating that these wastes can have other applications in addition to ethanol production.
