Cellobiose dehydrogenase production by Sclerotium species pathogenic to plants.
OBJECTIVE
Evaluation of various Sclerotium spp. as producers of the biotechnologically attractive enzyme cellobiose dehydrogenase.


RESULTS
All isolates of S. coffeicola, S. delphinii and S. rolfsii grown in shaken flasks on a cellulose-based medium produced appreciable amounts of the extracellular enzyme cellobiose dehydrogenase.


CONCLUSIONS
Cellobiose dehydrogenase seems to play an important role in phytopathogenic Sclerotium spp.; a possible function could be either in the degradation of rigid lignocellulose or as a protective mechanism against toxic quinones.


CONCLUSIONS
S. coffeicola and S. delphinii were identified as potent, not-yet-described producers of cellobiose dehydrogenase (CDH). The high levels of intact CDH produced by the different Sclerotium species should make them attractive producers for further studies and applications.
