Hidalgo, Mauricio; Steiner, Jeannette; Eyzaguirre, Jaime (PORTLAND PRESS, 1992-04)Beta-glucosidade was purified from the culture supernatant of penicillium purpurogenum. The purified enzyme was homogeneous on both nondenaturing and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. The ...

Díaz, René; Sapag, Amalia; Peirano, Alessandra; Steiner, Jeannette; Eyzaguirre, Jaime (ELSEVIER SCIENCE BV, 1997-03-18)The cDNA, for xylanase B from Penicillium purpurogenum was cloned and sequenced. This DNA encodes a protein of 208 amino acids which is expected to yield a protein of 183 residues upon processing of the N terminus. The ...

CULTURE CONDITIONS FOR ENHANCED CELLULASE PRODUCTION BY A NATIVE STRAIN OF PENICILLIUM-PURPUROGENUM Steiner, Jeannette; Socha, C.; Eyzaguirre, Jaime (RAPID SCIENCE PUBLISHERS, 1994-05)A cellulolytic wild-type strain of Penicillium purpurogenum was isolated from a soil sample in southern Chile. It grew best at 28-degrees-C from an inoculum of 4 x 10(7) spores/100 ml medium. Highest endoglucanase activity ...

Steiner, Jeannette; Carmona, P.; Ponce, C.; Berti, M.; Eyzaguirre, Jaime (KLUWER ACADEMIC PUBL, 1998-07)Penicillium purpurogenum was mutated with u.v. light to increase xylanase production. The best mutant, UV-64, was treated with N-methyl-N'-nitro-N-nitrosoguanidine and a second generation of mutants was obtained (NG-188 ...
