Article Synopsis
  • A study was conducted using various Aspergillus strains to test a medium with 20% tannic acid for effectively selecting black aspergilli species.
  • The 20% tannic acid medium successfully supported growth of all recognized black aspergilli species, indicating their capacity to thrive in this environment.
  • Genetic analysis revealed multiple tannase-like genes in A. niger, suggesting these fungi have a unique ability to degrade tannic acid, which could play a significant ecological role.

Fungi in which the haploid nuclei resulting from meiosis are linearly arranged in asci provide unique opportunities to analyse abnormal segregation. Any meiotic drive system in such fungi will be observed in a cross between a driving and a sensitive strain as spore killing: the degeneration of half the ascospores in a certain proportion of the asci. In a sample of some 100 strains isolated from a single natural population we have discovered at least six different meiotic drive elements (van der Gaag et al.
