Abstract
Manganese and lignin peroxidase (MnP, LiP) activities were measured in straw extracts from cultures of Phanerochaete chrysosporium. Out of s ix MnP substrates, the MBTH/DMAB (3-methyl-2-benzothiazolinone hydrazo ne/3-(dimethylamino)benzoic acid), gave the highest MnP activity. Dete ction of LIP activity as veratryl alcohol oxidation was inhibited by p henols in the straw culture extracts. Appropriate levels of veratryl a lcohol and peroxide (4 mM and 0.4 mM, respectively), and a restricted sample volume (not larger than 10%) were necessary to detect activity.
