Aspergillus terreus is a species of fungus in the genus Aspergillus, which is part of the phylum Ascomycota. It is known for its role in the production of the drug lovastatin, which is used to lower cholesterol levels. This species is also notable for its ability to cause aspergillosis, a type of infection that can affect the lungs and other organs.

Morphology

Aspergillus terreus is characterized by its distinctive conidiophores and conidia. The conidiophores are smooth and hyaline, while the conidia are typically spherical and have a rough surface. The colonies of A. terreus are usually brown to yellow-brown in color.

Habitat

Aspergillus terreus is commonly found in soil and decaying plant material. It thrives in warm and humid environments and can be isolated from various substrates, including compost, grains, and nuts.

Pathogenicity

Aspergillus terreus is an opportunistic pathogen that can cause aspergillosis in humans, particularly in immunocompromised individuals. The infection can manifest in various forms, including pulmonary aspergillosis, disseminated aspergillosis, and cutaneous aspergillosis. Treatment typically involves the use of antifungal medications such as voriconazole.

Industrial Applications

One of the most significant contributions of Aspergillus terreus to industry is its role in the production of lovastatin, a statin drug used to lower cholesterol levels. The fungus produces lovastatin as a secondary metabolite, which has been harnessed for pharmaceutical use.

Research

Research on Aspergillus terreus continues to explore its potential in biotechnology and medicine. Studies focus on its metabolic pathways, genetic makeup, and potential applications in drug production and bioremediation.
