Ignisphaera cupida sp. nov., a hyperthermophilic hydrolytic archaeon from a hot spring of Uzon (Kamchatka), and emended description of the genus Ignisphaera. Syst Appl Microbiol 2024; 47:126541. [PMID: 39084153 DOI: 10.1016/j.syapm.2024.126541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 07/12/2024] [Accepted: 07/24/2024] [Indexed: 08/02/2024]
Abstract
A novel strictly anaerobic hyperthermophilic archaeon, strain 4213-coT, was isolated from a terrestrial hot spring in the Uzon Caldera, Kamchatka (Russian Federation). Coccoid cells were present singly, in pairs, or aggregates, and occasionally were motile. The strain grew at 75-100 °C and within a pH range of 5.4-8.2 with the optimum at 92 °C and pH 6.4-6.7. Strain 4213-coT was a chemoorganoheterotroph, growing on proteinaceous substrates and mono-, di- and polysaccharides (starch, guar gum, xanthan gum). It did not require sodium chloride for growth. The complete genome of strain 4213-coT was 1.74 Mbp in size; its G+C content was 36.18 %. Genome analysis allowed to identify 25 genes encoding glycosidases involved in polysaccharide hydrolysis as well as genes of ADP-forming acetate-CoA ligase, lactate dehydrogenase and two [NiFe] hydrogenases responsible for acetate, lactate and hydrogen formation during fermentation. Moreover gene cluster encoding archaellum subunits was found. According to the phylogenomic analysis strain 4213-coT formed a species-level phylogenetic lineage within Ignisphaera genus. Our phylogenomic analysis also supports the delineation of the Ignisphaera genus into a separate family Ignisphaeraceae, as recently published. Here we propose a novel species Ignisphaera cupida, sp. nov. with type strain 4213-coT (=JCM 39446T=VKM B-3715T=UQM 41593T). Ecogenomic analysis showed that representatives of the Ignisphaera are thermophilic archaea, the majority of them were found in terrestrial hot springs and deep-sea hydrothermal vents. This study allowed a better understanding of physiology and ecology of Ignisphaeraceae - a rather understudied archaeal group.

Int J Biol Macromol 2024; 254:127966. [PMID: 37944726 DOI: 10.1016/j.ijbiomac.2023.127966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 11/02/2023] [Accepted: 11/06/2023] [Indexed: 11/12/2023]
Abstract
Endo-1,4-β-galactanase is an indispensable tool for preparing prebiotic β-galacto-oligosaccharides (β-GOS) from pectic galactan resources. In the present study, a novel endo-1,4-β-galactanase (PoβGal53) belonging to glycoside hydrolase family 53 from Penicillium oxalicum sp. 68 was cloned and expressed in Pichia pastoris GS115. Upon purification by affinity chromatography, recombinant PoβGal53 exhibited a single band on SDS-PAGE with a molecular weight of 45.0 kDa. Using potato galactan as substrate, PoβGal53 showed optimal reaction conditions of pH 4.0, 40 °C, and was thermostable, retaining >80 % activity after incubating below 45 °C for 12 h. Significantly, PoβGal53 exhibited relatively conserved substrate specificity for (1 → 4)-β-D-galactan with an activity of 6244 ± 282 U/mg. In this regard, the enzyme is in effect the most efficient endo-1,4-β-galactanase identified to date. By using PoβGal53, β-GOS monomers were prepared from potato galactan and separated using medium pressure liquid chromatography. HPAEC-PAD, MALDI-TOF-MS and ESI-MS/MS analyses demonstrated that these β-GOS species ranged from 1,4-β-D-galactobiose to 1,4-β-D-galactooctaose (DP 2-8) with high purity. This work provides not only a highly active tool for enzymatic degradation of pectic galactan, but an efficient protocol for preparing β-GOS.

Abstract
Lignocellulose is a plentiful and intricate biomass substance made up of cellulose, hemicellulose, and lignin. Cellulose and hemicellulose are polysaccharides characterized by different compositions and degrees of polymerization. As renewable resources, their applications are eco-friendly and can help reduce reliance on petrochemical resources. This review aims to illustrate cellulose, hemicellulose, and their structures and hydrolytic enzymes. To obtain desirable enzyme sources for the high hydrolysis of lignocellulose, highly stable, efficient and thermophilic enzyme sources, and new technologies, such as rational design and machine learning, have been introduced in detail. Generally, the efficient biodegradation of abundant natural biomass into fermentable sugars or other intermediates has great potential in practical applications.

Abstract
(Hyper)thermophilic archaeal glycosidases are enzymes that catalyze the hydrolysis of glycosidic bonds to break down complex sugars and polysaccharides at high temperatures. These enzymes have an unique structure that allows them to remain stable and functional in extreme environments such as hot springs and hydrothermal vents. This review provides an overview of the current knowledge and milestones on the structures and functions of (hyper)thermophilic archaeal glycosidases and their potential applications in various fields. In particular, this review focuses on the structural characteristics of these enzymes and how these features relate to their catalytic activity by discussing different types of (hyper)thermophilic archaeal glycosidases, including β-glucosidases, chitinase, cellulases and α-amylases, describing their molecular structures, active sites, and mechanisms of action, including their role in the hydrolysis of carbohydrates. By providing a comprehensive overview of (hyper)thermophilic archaeal glycosidases, this review aims to stimulate further research into these fascinating enzymes.

Abstract
A sustainable bioeconomy that includes increased agricultural productivity and new technologies to convert renewable biomass to value-added products may help meet the demands of a growing world population for food, energy and materials. The potential use of plant biomass is determined by the properties of the cell walls, consisting of polysaccharides, proteins, and the polyphenolic polymer lignin. Comprehensive knowledge of cell wall glycan structure and biosynthesis is therefore essential for optimal utilization. However, several areas of plant cell wall research are hampered by a lack of available pure oligosaccharide samples that represent structural features of cell wall glycans. Here, we provide an update on recent chemical syntheses of plant cell wall oligosaccharides and their application in characterizing plant cell wall-directed antibodies and carbohydrate-active enzymes including glycosyltransferases and glycosyl hydrolases, with a particular focus on glycan array technology.
