Table 1 Pigment production by Neurospora spp. using different experimental set-ups

From: Filamentous ascomycetes fungi as a source of natural pigments

  1. aTotal carotenoids content is determined by spectral absorption at specific wavelengths maxima depending on which solvent the carotenoids are extracted in. The absorbance value correlates to the amount of carotenoids present in the samples
  2. bSolid-state fermentation (SSF), submerged fermentation (SmF)
