Caldicellulosiruptor Core and Pangenomes Reveal Determinants for Noncellulosomal Thermophilic Deconstruction of Plant Biomass
JOURNAL OF BACTERIOLOGY, 194(15), 4015–4028.
MeSH headings : Adhesins, Bacterial / analysis; Adhesins, Bacterial / genetics; Biomass; Carbohydrate Metabolism; Cellulases / analysis; Cellulases / genetics; Cellulose / metabolism; Genetic Variation; Genome, Bacterial; Gram-Positive Bacteria / enzymology; Gram-Positive Bacteria / genetics; Metabolic Networks and Pathways / genetics; Plants / chemistry; Proteome / analysis
TL;DR:
Taking into account the core genomes, pangenomes, and individual genomes, the ancestral Caldicellulosiruptor was likely cellulolytic and evolved, in some cases, into species that lost the ability to degrade crystalline cellulose while maintaining the capacity to hydrolyze amorphous cellulose and hemICEllulose.
