World J Microbiol Biotechnol 42 103\u00a0<a href=\"https:\/\/doi.org\/10.1007\/s11274-026-04840-1\">https:\/\/doi.org\/10.1007\/s11274-026-04840-1<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Abs1\">Abstract<\/h2>\n\n\n\n<p>A thermophilic bacterium, designated&nbsp;<em>Geobacillus<\/em>&nbsp;sp. Geo 8.1, was isolated from a submarine hydrothermal spring of Ischia Island (Italy) and characterized through genomic and biochemical analyses to evaluate its biotechnological potential. The draft genome (3.41 Mbp; GC 52.5%) revealed 3,751 coding sequences, including complete pathways for carbohydrate, lipid, and protein metabolism, and enzymes involved in stress response and hydrocarbon degradation. Phylogenomic and digital DNA\u2013DNA hybridization analyses placed Geo 8.1 within the&nbsp;<em>Geobacillus thermoleovorans<\/em>\/<em>Geobacillus kaustophilus<\/em>&nbsp;cluster. Functional annotation highlighted diverse genes encoding thermostable hydrolases such as xylanases, \u03b2-xylosidases, lipases, proteases, and \u03b1-amylases, together with catalases and dehalogenases relevant to environmental and industrial applications. Crude enzyme extracts exhibited strong xylanase activity (184 U\/mL at 65&nbsp;\u00b0C), and thin-layer chromatography confirmed the production of xylose as the major hydrolysis product, indicating the coordinated action of endo-xylanase and \u03b2-xylosidase. Genome reconstruction further demonstrated a complete D-xylose utilization pathway linking hemicellulose degradation to central carbon metabolism. The combined genomic and enzyme data reveal&nbsp;<em>Geobacillus<\/em>&nbsp;sp. Geo 8.1 represents a promising thermophilic biocatalyst for producing thermostable enzymes applicable to lignocellulose valorization, bioremediation, and various industrial processes.<\/p>\n\n\n\n<p>Read more at: <a href=\"https:\/\/link.springer.com\/article\/10.1007\/s11274-026-04840-1\">https:\/\/link.springer.com\/article\/10.1007\/s11274-026-04840-1<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Song\u00fcl Ya\u015far Y\u0131ld\u0131z, Ilaria Finore, Bora Ceylan, Do\u011fa Uma\u00e7, Ceyda Kasavi, Gennaro Finore, Antonio Federico, Francesco Nizzolino, Luigi Leone, Annarita Poli &amp; Ebru Toksoy \u00d6ner (UO06) 2026 Genomic and functional insights into the thermophilic strain Geobacillus sp.
