Abstract
The ability of accumulating androsta-1, 4-diene-3, 17-dione (ADD) in the digestion of cholesterol by Arthrobacter simplex IAM 1660 was examined with 167 compounds and (i) chelating agents, (ii) Ni2+, Co2+, Hg2+, As3+, Sb3+, Bi3+, Cd2+, SeO32-, and AsO2- ions, and (iii) redox dyes were found effective for ADD accumulation. Ionic state of the chelating agents was unfovorable for ADD accumulation but inactive ethylaenediamine tetraacetic acid could be turned effective with aid of surface active agents and penicilline. Lipophilic structure of the chelating agents was required probably for its penetration through the cell membrane. The target process of the ADD accumulating agents was supposed as 9α-hydroxylation and their possible mechanism of inhibiting 9α-hydroxylation is discussed.Keywords
