Thermoascus
Genus of soil fungi
From Wikipedia, the free encyclopedia
Thermoascus is a genus of soil fungi in the family Trichocomaceae. Species in the genus are characterized by the production of heat-resistant ascospores. Thermoascus was circumscribed by German botanist Hugo Miehe in 1907.[1]

The type species, Thermoascus aurantiacus, is of research interest because it secretes heat-resistant hydrolase enzymes that could possibly be used in biotechnological applications, such as the conversion of biomass to biofuels.[2] Genetic tools have been developed to genetically edit Thermoascus aurantiacus, such as an Agrobacterium tumefaciens-mediated transformation protocol and a CRISPR-Cas9 gene editing system, which have been used to overexpress genes that correspond to production of enzymes that break down plant matter and inactivate genes.[3]

Another described species, Thermoascus isatschenkoi Malchevskaya (1939),[8] is considered doubtful due to a lack of examinable material and an incomprehensive description.[9]
