The genome sequence and gene prediction of Thermomyces dupontii NRRL 2155 have not been determined by the Joint Genome Institute (JGI), but were downloaded from CSFG on July 31, 2022. In order to allow comparative analyses with other fungal genomes sequenced by the JGI, a copy of this genome is incorporated into Mycocosm. Please note that this copy of the genome is not automatically updated. JGI tools were used to automatically annotate predicted proteins.

Thermomyces dupontii, previously Talaromyces thermophilus, is a thermophilic fungus from the Trichocomaceae family present worldwide. Its growth temperature optimum is 45 ºC and different strains have been isolated from fermented straw, manure, compost and plant material and soil (1). Thermomyces dupontii can grow in presence of xylan and wheat bran as sole source of carbon source and several biomass-active enzymes have been characterized (2-4). The study of T. dupontii genome will provide a source of information regarding thermostable enzymes involved in biomass degradation.
