15α-hydroxylation of 13-ethyl-estr-4-ene-3,17-dione using immobilized Penicillium raistrickii entrapped in calcium alginate gel was studied. The conversion conditions, which affected hydroxylation such as substrate concentration, the time to add substrate, conversion duration, were investigated. The results show that, the immobilized Penicillium raistrickii can be utilized repeatedly five times with no obvious decline of hydroxylation ability.
