2001 article

Galactomannanases Man2 and Man5 from Thermotogaspecies: Growth physiology on galactomannans, gene sequence analysis, and biochemical properties of recombinant enzymes

Parker, K. N., Chhabra, S. R., Lam, D., Callen, W., Duffaud, G. D., Snead, M. A., … Kelly, R. M. (2001, September 13). Biotechnology and Bioengineering, Vol. 75, pp. 322–333.

By: K. Parker n, S. Chhabra n, D. Lam*, W. Callen*, G. Duffaud n, M. Snead*, J. Short*, E. Mathur*, R. Kelly n 

author keywords: Thermotoga; hyperthermophile; hemicellulase; glycosyl hydrolase; galactomannan; beta-mannanase; beta-mannosidase
MeSH headings : Amino Acid Sequence; Bacteria / enzymology; Bacteria / genetics; Bacteria / growth & development; Bacterial Proteins; Galactose / analogs & derivatives; Mannans / metabolism; Mannosidases / chemistry; Mannosidases / genetics; Mannosidases / metabolism; Microscopy, Electron; Molecular Sequence Data; Sequence Homology, Amino Acid; beta-Mannosidase
topics (OpenAlex): Biofuel production and bioconversion; Enzyme Production and Characterization; Polysaccharides and Plant Cell Walls
TL;DR: The identification of the galactomannan-degrading enzymes in these Thermotoga species adds to the list of biotechnologically important hemicellulases produced by members of this hyperthermophilic genera. (via Semantic Scholar)

1998 article

Isolation and Characterization of Thermococcus barossii, sp. nov., a Hyperthermophilic Archaeon Isolated from a Hydrothermal Vent Flange Formation

Duffaud, G. D., d'Hennezel, O. B., Peek, A. S., Reysenbach, A.-L., & Kelly, R. M. (1998, March 1). Systematic and Applied Microbiology, Vol. 21, pp. 40–49.

By: G. Duffaud n, O. d'Hennezel n, A. Peek*, A. Reysenbach* & R. Kelly n 

author keywords: Thermococcus barossii; hyperthermophiles; 16S rRNA; growth physiology
MeSH headings : Anti-Bacterial Agents / pharmacology; Chloramphenicol; Culture Media; DNA, Archaeal / analysis; DNA, Ribosomal / analysis; Microbial Sensitivity Tests; Pacific Ocean; Phylogeny; RNA, Ribosomal, 16S / genetics; Seawater; Sequence Analysis, DNA; Streptomycin; Thermococcus / classification; Thermococcus / drug effects; Thermococcus / growth & development; Thermococcus / isolation & purification; Thermococcus / ultrastructure
topics (OpenAlex): Microbial Community Ecology and Physiology; Genomics and Phylogenetic Studies; Methane Hydrates and Related Phenomena
TL;DR: Based on the high degree of similarity among members of the genus Termococcus for the criteria used thus far, aspects of enzymology may be an important mechanism of differenting one species from another. (via Semantic Scholar)
