The hydroxylase activities of new strains such as Curvularia lunata, C. geniculata, C. eragrostidis, C. prasadii, Ulocladium botrytis, Alternaria tenuis, and Fusarium oxysporum toward three steroid substrates, namely, androstenedione (AD), cortexolone (S), and dehydroepiandrosterone acetate (DAA), were characterized. The 9α-hydroxylase activity of C. lunata(More)
The steroid-transforming activity of free and immobilized cells of Pimelobacter simplex VKPM Ac-1632 entrapped in an operationally stable macroporous poly(vinyl alcohol) cryogel was studied. It was shown that the macroporous matrix of the carrier did not create any diffusional limitations for steroid access to the cells or the removal of the transformation(More)
The main and side products of hydroxylation by the C. lunata VKPM F-981 mycelium of fourteen Δ4-3-ketosteroids of the estrane, androstane, and pregnane series and six of their Δ5-3β-hydroxy analogues were identified by H1PMR spectroscopy and comparison with standard samples. The obtained experimental data are considered in terms of the triangular model of(More)
