Abstract

Outside and inside corn cob were used to study ligninolytic enzymes produced by Phanerochaete chrysosporium BKM-F-1767 (ATCC 24725) during solid state fermentation conditions. In a previous work by employing a mixture of outside and inside corn cob, we achieved a maximum MnP activity of 96 U l−1 but LiP activities were low. In the present work we determined which part of the corn cob is more suitable in order to obtain high ligninolytic activities. We could find MnP activities about 300 U l−1 by employing inside corn cob as a carrier and a maximum LiP activity of 24 U l−1.  In a subsequent experiment, using inside corn cob as a carrier, we could considerably improve ligninolytic enzymes production, by supplementing the medium with Tween 80 (0.5% v/v). We obtained a maximum MnP activity of 384 U l−1and a maximum LiP activity of 155 U l−1.
