Summary
Basidiomycetes fungi from Spain were screened for antimicrobial properties. Many extracts showed antibacterial and antifungal activity, with variations observed at the genus and species levels.
Area of Science:
- Mycology
- Microbiology
- Natural Product Chemistry
Background:
- Basidiomycetes fungi are a significant source of bioactive natural products.
- Screening programs are crucial for discovering novel antimicrobial compounds from fungal resources.
- Understanding the distribution of antimicrobial activity within fungal taxa is important for targeted drug discovery.
Purpose of the Study:
- To evaluate the antimicrobial potential of basidiomycetes collected in Spain.
- To compare the antimicrobial activity of basidiomycetes with other fungal groups.
- To investigate the distribution patterns of antimicrobial activity within basidiomycetes.
Main Methods:
- A screening program was established to test extracts from 317 basidiomycete isolates (204 species).
- Antimicrobial activity was assessed against human clinical pathogens and laboratory controls.
- Activity was quantified and compared across different taxonomic levels (suprageneric, genus, species).
Main Results:
- Antimicrobial activity was detected in extracts from 45% of the isolates (109 species).
- Antibacterial activity was more prevalent than antifungal activity.
- Antimicrobial activity varied significantly at the genus and infraspecific levels, indicating uneven distribution.
Conclusions:
- Basidiomycetes represent a valuable resource for discovering antimicrobial agents.
- The distribution of antimicrobial compound production is not uniform across basidiomycetes.
- Further research into specific genera and infraspecific variations could yield novel drug leads.
