Special Issue Information

Dear Colleagues,

The intention of launching this Special Issue is to disclose the latest developments in fermentative hydrogen production. The theme has been exhaustively investigated over more than a decade; however, this technology is still waiting for the scaling up of cost-effective processes.

What are the challenges that fermentative hydrogen processes face to reach maturity? To help us answering this question, we kindly invite you to contribute to this Special Issue, covering the following topics:

Biomass: the search for new, inexpensive and widely available biomass resources, especially those that represent waste streams, the use of multifeedstock combinations that may help overcome process scale constraints, additional aspects related with sustainability and logistics of the biomass feedstock are exemplary issues to address, that may bring new perspectives to the study of biohydrogen production.

Microorganisms: low productivity and robustness are the major challenges in the scale up of the fermentative hydrogen production. This Special Issue invites articles including, but not limited to, novel hydrogen-producing microorganisms with improved characteristics for the establishment of robust and productive hydrogen processes. Articles which deal with the latest hot topics in synthetic biology including artificial genes, metabolic engineering of strains, as well as definition and monitoring of engineered microbial consortia, and possibly the development of certified starters are of special interest. Additionally, articles which discuss bioaugmentation strategies to outperform natural microbial consortia are welcome.

Production and aplications: articles focusing advances in process optimization, introducing innovative and more efficient schemes of process integration, including fuel cell applications, disclosing new potential applications that comprise, e.g., ecentralized production possibilities, exploring the development of hydrogen biorefineries and the contribution of co-metabolites production, and reporting a realistic appraisal of the technological and economic viability of biological hydrogen production, are invited.

Chestnut shells (CS) are an agronomic waste generated from the peeling process of the chestnut fruit, which contain 2.7–5.2% (w/w) phenolic compounds and approximately 36% (w/w) polysaccharides. In contrast with current shell waste burning practices, this study proposes a CS biorefinery that integrates biomass pretreatment, recovery of bioactive molecules, and bioconversion of the lignocellulosic hydrolyzate, while optimizing materials reuse. The CS delignification and saccharification produced a crude hydrolyzate with 12.9 g/L of glucose and xylose, and 682 mg/L of gallic acid equivalents. The detoxification of the crude CS hydrolyzate with 5% (w/v) activated charcoal (AC) and repeated adsorption, desorption and AC reuse enabled 70.3% (w/w) of phenolic compounds recovery, whilst simultaneously retaining the soluble sugars in the detoxified hydrolyzate. The phenols radical scavenging activity (RSA) of the first AC eluate reached 51.8 ± 1.6%, which is significantly higher than that of the crude CS hydrolyzate (21.0 ± 1.1%). The fermentation of the detoxified hydrolyzate by C. butyricum produced 10.7 ± 0.2 mM butyrate and 63.9 mL H2/g of CS. Based on the obtained results, the CS biorefinery integrating two energy products (H2 and calorific power from spent CS), two bioproducts (phenolic compounds and butyrate) and one material reuse (AC reuse) constitutes a valuable upgrading approach for this yet unexploited waste biomass.
