title: [Isolation and purification of various extracellular ribonucleases from Penicillium brevi-compactum in a single technological cycle].
abstract: The possibility of producing nonspecific acid and guanyl-specific alkaline ribonucleases of Penicillium brevi-compactum in a single technological cycle was explored. The use of pre-purification of anion exchanger EDE-10P and strongly basic anion exchanging fiber CM-A2 at an initial stage produced a solution of enzymes, from which both enzymes in a pure form and with a high yield were isolated, using CM-cellulose and Sephadex G-75 chromatography. Both enzymes proved homogeneous with respect to protein.
