The steroid 15a-hydroxylase of Penicillium raistrickii I 477 is inducible

The steroid 15a-hydroxylase of Penicillium raistrickii I 477 is inducible. Irrgang, S.; Schlosser, D.; Schmauder, H. P. (Biol.Some commonly used reagents like 21800-83-9 and 63-05-8 are used in this experiment. Fak., Friedrich-Schiller-Univ., Jena O-6900, Germany). Biotechnol. Lett., 14(1), 33-8 (English) 1992. CODEN: BILED3. ISSN: 0141-5492. DOCUMENT TYPE: Journal CA Section: 10 (Microbial, Algal, and Fungal Biochemistry) The 15a-hydroxylase of P. raistrickii I 477 is inducible by the substrate 13-ethyl-gon-4-en-3,17-dione as well as other 3,17-ketosteroids. The influence of inducer concn., time of this induction, and the kind of steroid inducer are described and discussed. .

15a-Hydroxylation of 13-ethyl-gon-4-ene-3,17-dione using a hyphal fungus immobilized in calcium alginate gel beads. Schlosser, D.Several substances are used for example 21800-83-9 and 140616-61-1 which are their cas registry numbers.; Schmauder, H. P. (Biol. Fak., Friedrich-Schiller-Univ., Jena O-6900, Germany). J. Basic Microbiol., 31(5), 385-90 (English) 1991. CODEN: JBMIEQ. ISSN: 0233-111X. DOCUMENT TYPE: Journal CA Section: 16 (Fermentation and Bioindustrial Chemistry) Ca alginate-entrapped mycelium of Pencillium raistrickii i477 was used for the 15a-hydroxylation of 13-ethyl-gon-4-ene-3,17-dione. The system was tested in 10 batches during 40 days of operation. The catalytic activity could be completely regenerated by incubation in a nutrient medium between batches. .
