Special Issue Information

Dear Colleagues,

The Special Issue entitled "Technological Advances in Lignocellulosic Biomass Conversion to Bioenergy" aims to present recent research on any aspect of the reclaiming of lignocellulosic biomass (including organic wastes) for the production of bioenergies. Lignocellulosic biomass and derived organic wastes constitute one of the main resources in our biosphere whose proper reclaiming (obtaining bioenergies, for instance) can be a significant contribution to the sustainable development of modern societies.

Reports on innovative conversion processes of lignocellulosic biomass are encouraged. Some of its focal points include, but are not limited to, the following subjects: 

  1. Liquid biofuels from lignocellosic biomass and organic wastes
  2. Gas biofuels from lignocellulosic biomass and organic wastes
  3. Other bioenergies (i.e., bioelectricity, bioelectrochemical H2 and methane) from lignocellulosic biomass and organic wastes
  4. Biorefineries from lignocellulosic biomass and organic wastes for bioenergies and value-added bioproducts generation
  5. Innovative conversion processes of lignocellulosic biomass
  6. Sustainability issues on bioconversion of lignocellulosic biomass (life cycle assessment, environmental sustainability evaluation, economic and social sustainabilities, metrics development)
  7. Innovative and improved conventional upstream and downstream processes to assist the bioconversion of lignocellulosic biomass to bioenergies
  8. Evaluation of circularity of bioconversion processes of lignocellulosic biomass and organic wastes to bioenergies
  9. Comparison studies of lab scale and full scale bioenergies from lignocellulosic biomass and organic wastes and conventional technologies such as incineration with energy recovery and landfilling
  10. Economic analysis of the conversion of lignocellulosic biomass and organic wastes to bioenergies

Reviews, original research, and communications are welcome. Since the key words and the topics list are not exhaustive, please feel free to consult with me regarding the suitability of your intended article.

A biocatalyst has been developed for application in the simultaneous isomerization and fermentation (SIF) of xylose, which could enable operation in repeated batches and the use of xylose from biomass hemicellulose for the production of second-generation (2G) ethanol. To this end, the enzyme xylose isomerase (XI) was immobilized on eleven different supports (based on chitosan, modified silica, agarose and magnetic supports) to obtain a derivative that is stable under process conditions and easy to recover from the fermented medium for future industrial application in biorefineries. Immobilization was performed with 5 mg/gsupport, with a support-to-suspension ratio of 1:20. Phosphate (pH 7.0) and carbonate–bicarbonate (pH 10.05) buffer were used for uni-point and multi-point immobilization, respectively. Among the immobilized enzymes, the magnetic microparticle Captura N exhibited the best immobilization parameters (67% recovered activity and half-life of 10 h at 80 °C), in addition to its magnetic properties, which facilitates purification. The SIF of crude sugarcane straw acid hydrolysate was carried out in repeated batches using XI-chitosan and XI-Captura N. Although economically promising, chitosan-based supports did not enhance enzyme stability. Therefore, magnetic microparticles are a promising option as XI immobilization supports for biorefinery applications. Full article
