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 this Special Issue, titled "Lignocellulosic Biomass Valorisation, 2nd Edition", 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.

Bioethanol manifests an extraordinary potential to overcome the severe energy crises and reliance on fossil fuels, yet it supports the sustainable and cost-effective production of fuels for automobile engines and contributes to the reduction of greenhouse gas (GHG) emissions and other global climate-related challenges. The present study examines the potential of Mixed Lignocellulosic Biomass (MLB) as a sustainable feedstock for the consistent year-round production of bioethanol. The primary MLB sources considered in this research to underscore the significance of this heterogeneous strategy include sweet sorghum bagasse (SSB), sugarcane bagasse (SCB), and date palm trunk (DPT). Each of the three feedstocks, i.e., SSB, SCB, and DPT, were individually subjected to alkaline pretreatment, a step aimed at breaking down structural barriers and facilitating greater release of fermentable sugars during fermentation. Likewise, the alkaline-pretreated biomasses were subjected to simultaneous saccharification and fermentation (SSF) for 96 h, both individually as well as in various combined proportions. Individually, pretreated sweet sorghum bagasse (SSB) fibers produced the highest ethanol concentration, of 30.79 ± 0.44 g/L; an ethanol yield of 0.40 ± 0.62 g/g; an ethanol productivity of 0.42 ± 0.87 g/L/h; and a theoretical ethanol yield of 79.81% at 72 h. In contrast, the combination of MLB (50% of pretreated SSB and 50% of DPT fibers) produced a significantly higher ethanol concentration of 31.47 ± 0.57 g/L and an ethanol productivity of 0.653 ± 0.24 g/L/h in much less time, i.e., 48 h of SSF fermentation. The empirical data confirms that MLB offers a sustainable paradigm for ethanol biosynthesis by curtailing fermentation time and optimizing economic and operational efficacy. Full article
