[Differentiation of Blakeslea trispora mycelium in relation to carotene production].

Carotene synthesis by Blakeslea trispora is accompanied by a decrease in the rate of the main metabolic processes (protein synthesis, respiration) and changes in the bioenergetic pool of the mycelium. Considerable changes occur at the same time in the cytology of the microscopic fungus: the cell wall of the culture containing considerable amounts of carotene consists of many layers and peculiar thickened regions; partitions are formed; the nuclei are in the stage of interphase; lipid inclusions are larger and their number is higher.
