Species Information (from MycoBank)

Current name

Talaromyces thermophilus Stolk 1965 [1]

Associated anamorph

Penicillium dupontii Griffon & Maublanc 1911 [2]

Taxonomic synonyms
Talaromyces dupontii (Griffon & Maublanc) Apinis 1963 [3]

Lineage (from MycoBank)

Ascomycota; Eurotiomycetes; Eurotiales; Trichocomaceae; Talaromyces


Has been isolated from fermented straw, manure, compost, plant material and soil (1,4). Temperature for growth is 45 oC [1]. Strains of Talaromyces thermophilus have been found in North America, Asia and Europe.

Interesting Features

Decomposer of lignocellulose

Talaromyces thermophilus can grow in presence of xylan and wheat bran as sole source of carbon [5].The organism is not able to grow using filter paper, but nevertheless secretes enzymes that hydrolyze carboxymethylcellulose [6].

Source of thermophilic enzymes

Biomass-active enzymes of Talaromyces thermophilus that have been characterized include phytases [7,8], beta D- xylosidase [9], beta-galactosidase (10, 11), beta-glucosidase (11) and xylanase [5].
