The emerging energy transition is particularly described as a move towards a cleaner, lower-carbon system. In the context of the global shift towards sustainable energy sources, this paper reviews the potential and roadmap for hydrogen energy as a crucial component of the clean energy landscape. The primary objective is to present a comprehensive literature overview, illuminating key themes, trends, and research gaps in the scientific discourse concerning hydrogen production and energy policy. This review focuses particularly on specified geographic contexts, with an emphasis on understanding the unique energy policies related to renewable energy in Brazil, Austria, and Germany. Given their distinct social systems and developmental stages, this paper aims to delineate the nuanced approaches these countries adopt in their pursuit of renewable energy and the integration of hydrogen within their energy frameworks. Brazil exhibits vast renewable energy potential, particularly in wind and solar energy sectors, positioning itself for substantial growth in the coming years. Germany showcases a regulatory framework that promotes innovation and technological expansion, reflecting its highly developed social system and commitment to transitioning away from fossil fuels. Austria demonstrates dedication to decarbonization, particularly through the exploration of biomethane for residential heating and cooling.

“…Fermentative anaerobes are biotechnologically relevant microorganisms; the push for renewable energy has identified them as microbial platforms because of their ability of convert plant polysaccharides, including in some cases microcrystalline cellulose, into industrially important products, such as acetone, butanol and ethanol ( Bing et al, 2022 ). In fact, bioprocesses, used to produce industrial solvents prior to the emergence of petrochemicals, have received renewed attention in recent years with the development of molecular genetic tools to facilitate metabolic engineering of fermentative anaerobes ( Lee et al, 2012 ; Charubin et al, 2018 ).…”

“…Caldicellulosiruptor species have since been isolated from globally diverse thermal features (e.g., Yellowstone National Park, United States; Hveragerði, Iceland; Nagano Prefecture, Japan; Kamchatka, Russia; Changbai, China) and, based on metagenomic data ( Blumer-Schuette, 2020 ), yet uncharacterized species likely inhabit neutral, terrestrial, thermal features wherever they occur on earth. To date, Caldicellulosiruptor bescii ( Kataeva et al, 2009 ; Yang et al, 2010 ; f. Anaerocellum thermophilum ; Svetlichnyi et al, 1990 ) has been the focus of most studies of these bacteria, given the availability of molecular genetic tools ( Chung et al, 2014 ; Lipscomb et al, 2016 ) and biotechnological potential ( Lee et al, 2020 ; Bing et al, 2022 ) of this species. Not only has C. bescii been engineered to produce industrial chemicals ( Williams-Rhaesa et al, 2018 ; Straub et al, 2020 ), but can also degrade and ferment transgenic lignocellulose ( Straub et al, 2019 ).…”

Whither the genus Caldicellulosiruptor and the order Thermoanaerobacterales: phylogeny, taxonomy, ecology, and phenotype

The order Thermoanaerobacterales currently consists of fermentative anaerobic bacteria, including the genus Caldicellulosiruptor. Caldicellulosiruptor are represented by thirteen species; all, but one, have closed genome sequences. Interest in these extreme thermophiles has been motivated not only by their high optimal growth temperatures (≥70°C), but also by their ability to hydrolyze polysaccharides including, for some species, both xylan and microcrystalline cellulose. Caldicellulosiruptor species have been isolated from geographically diverse thermal terrestrial environments located in New Zealand, China, Russia, Iceland and North America. Evidence of their presence in other terrestrial locations is apparent from metagenomic signatures, including volcanic ash in permafrost. Here, phylogeny and taxonomy of the genus Caldicellulosiruptor was re-examined in light of new genome sequences. Based on genome analysis of 15 strains, a new order, Caldicellulosiruptorales, is proposed containing the family Caldicellulosiruptoraceae, consisting of two genera, Caldicellulosiruptor and Anaerocellum. Furthermore, the order Thermoanaerobacterales also was re-assessed, using 91 genome-sequenced strains, and should now include the family Thermoanaerobacteraceae containing the genera Thermoanaerobacter, Thermoanaerobacterium, Caldanaerobacter, the family Caldanaerobiaceae containing the genus Caldanaerobius, and the family Calorimonaceae containing the genus Calorimonas. A main outcome of ANI/AAI analysis indicates the need to reclassify several previously designated species in the Thermoanaerobacterales and Caldicellulosiruptorales by condensing them into strains of single species. Comparative genomics of carbohydrate-active enzyme inventories suggested differentiating phenotypic features, even among strains of the same species, reflecting available nutrients and ecological roles in their native biotopes.

“…Second, high temperature can also improve the solubility of substrates such as polysaccharides, improve the utilization rate of raw materials, reduce the viscosity of fermentation broth, lessen the pressure of homogenization and aeration, and increase the load of the substrate. In addition, increased temperature allows a high synergistic recovery rate of volatile products through distillation or gas extraction, thereby reducing product inhibition and extending the fermentation period of the culture, ultimately increasing the fermentation yield 7 , 8 , 9 . Thermophiles are also considered to be one of the most important sources of thermostable enzymes related to industrial manufacture.…”

Thermus thermophilus is an attractive species in the bioindustry due to its valuable natural products, abundant thermophilic enzymes, and promising fermentation capacities. However, efficient and versatile genome editing tools are not available for this species. In this study, we developed an efficient genome editing tool for T. thermophilus HB27 based on its endogenous type I-B, I-C, and III-A/B CRISPR-Cas systems. First, we systematically characterized the DNA interference capabilities of the different types of the native CRISPR-Cas systems in T. thermophilus HB27. We found that genomic manipulations such as gene deletion, mutation, and in situ tagging could be easily implemented by a series of genome-editing plasmids carrying an artificial self-targeting mini-CRISPR and a donor DNA responsible for the recombinant recovery. We also compared the genome editing efficiency of different CRISPR-Cas systems and the editing plasmids with donor DNAs of different lengths. Additionally, we developed a reporter gene system for T. thermophilus based on a heat-stable β-galactosidase gene TTP0042, and constructed an engineered strain with a high production capacity of superoxide dismutases by genome modification.
