title: Adenylate energy charge and the steroid 11 alfa-hydroxylase activity in Monosporium olivaceum during growth and starvation.
abstract: During growth of Monosporium olivaceum its energy charge, E.C., (i.e. the adenylates ratio ATP + 0.5 ADP/ATP + ADP + AMP) increased from an initial value of 0.59 up to 0.85 after 25 hr of growth and then decreased to 0.51. The increase of energy charge was followed by the decrease of the activity of the 11 alpha-hydroxylase of cortexolone. This occured very clearly in the starved mycelium. Highest hydroxylation activity was observed when the lowest E.C. level (0.39-0.33) was reached.
