Production of Dye-Decolorizing Peroxidase(rDyP) from Complex Substrates by Repeated-Batch and Fed-Batch Cultures of Recombinant Aspergillus oryzae(ENVIRONMENTAL BIOTECHNOLOGY)

概要

We examined production levels of dye-decolorizing peroxidase(rDyP) by recombinant Aspergillus oryzae using wheat bran and rice bran powders in repeated-batch and fed-batch cultures. Similar average rDyP productivities were observed in repeated-batch cultures using wheat bran powder and rice bran powder. Average rDyP productivities in fed-batch cultures were slightly lower than those in repeated-batch cultures. The rDyP production was affected by the addition of K_2HPO_4 in the repeated-batch and fed-batch cultures using wheat bran powder. All average rDyP productivities in this study were significantly higher than those for any other peroxidases previously reported.
