The effect of antimycin a on carotenogenesis in Verticillium agaricinum.

Antimycin A did not induce carotenogenesis in dark grown cultures of V. agaricinum, but total protein was increased. In light, antimycin A did not affect total carotenoids, although protein was slightly increased. The results suggest that antimycin A could not have acted here as an inducer for the synthesis of specific carotenogenic enzymes or by inactivating a repressor as has been suggested for certain bacteria.
