title: Microbial transformation of 13-ethyl-3-methoxy-8,14-seco-gona-1,3,5(10),9(11)-tetraene-14, 17-dione to its 17-beta hydroxy derivative by Pichia farinosa in pilot plant fermentors.
abstract: Parameters for microbial transformation of 13-ethyl-3-methoxy-8, 14-seco-gona-1,3,5 (10), 9(11)-tetraene-14,17-dione to its 17 beta-hydroxy derivative by P. farinosa have been standardised in pilot plant fermentors. The yield of the pure crystalline compound was 80%.
