Aspergillus clavatonanicus is a species of fungus in the genus Aspergillus, belonging to the Clavati section. It was first described in 1955 by the mycologists Batista, H. Maia, and Alecrim, based on a study of onychomycosis (fungal nail infection) caused by this organism, published in the Anais da Faculdade de Medicina da Universidade do Recife.
Taxonomy and Classification
- Kingdom: Fungi
- Division: Ascomycota
- Class: Eurotiomycetes
- Order: Eurotiales
- Family: Aspergillaceae
- Genus: Aspergillus
- Section: Clavati
Secondary Metabolites
A. clavatonanicus is known to produce a variety of bioactive secondary metabolites, including:
- Antafumicins
- Glyanthrypine
- Kotanins
- Tryptoquivalines
- Tryptoquivalones
Ecology and Significance
The species has been identified as an endophytic fungus associated with various plants, including mangrove species and medicinal plants such as Mirabilis jalapa. Studies have shown that A. clavatonanicus can produce clavatol and patulin, compounds that exhibit inhibitory activity against several plant-pathogenic fungi. It has also been investigated for its antimicrobial properties and its potential as a source of bioactive secondary metabolites.
