Summary
The biogenesis of the carotenoids inPhycomyces is studied as function of the medium. Theβ-carotene being the essentiel carotenoid of this fungi. A medium is prepared in which glucose and asparagine are replaced by ammonium lactate. In this medium there is a development but no formation of carotene. The presence of sodium acetate gives a normal carotenoid formation. The acetate reacts like a precursor of the carotene ofPhycomyces.
