TL;DR
A new heat-loving fungus from a volcano in Mexico was discovered and studied for its potential in industry and plant growth.
Contribution
The first characterization of a thermophilic endophytic strain of Aspergillus brasiliensis from a volcanic crater, including genomic and functional analysis.
Findings
A. brasiliensis E_15.1 survives at 60°C and neutral pH with high thermostability.
The fungus degrades complex carbohydrates and produces enzymes with industrial potential.
It contains genes for biosynthesis of clavaric acid, a compound with antitumor activity.
Abstract
Thermophilic fungi have been seldom studied despite the fact that they can contribute to understanding ecological mechanisms of adaptation in diverse environments and have attractive toolboxes with a wide range of biotechnological applications. This work describes for the first time an endophytic and thermophilic strain of Aspergillus brasiliensis that was isolated in the crater of the active volcano “El Chichonal” in Mexico. This strain was capable of surviving in soil with a temperature of 60 °C and a pH of neutral acidity, which preluded a high thermostability and a potential in industrial application. The complete genome of A. brasiliensis E_15.1 was sequenced and assembled in 37 Mb of genomic DNA. We performed a comprehensive phylogenomic analysis for the precise taxonomic identification of this species as a novel strain of Aspergillus brasiliensis. Likewise, the predicted coding…
