Carboxymethyl Cellulase Activity In The Myxomycete Physarum-Polycephalum
Abbreviated Journal Title
Carboxymethyl cellulase (CMCase) activity at different life cycle stages in Physarum polycephalum was measured viscometrically in homogenized axenic cultures incubated with CMC. Protein concentrations were determined using the Bio-Rad (Coomassie Blue) assay. Mean activity for several dilutions of the homogenized samples ranged from 318 CMCase activity units/hr/mg protein in old plasmodia to 2423 CMCase units/hr/mg protein in dry spores. Activity in spores and sclerotia was higher than in a vegetative Plasmodium. This CMCase activity level is comparable to that found in some true fungi and suggests that Myxomycetes may utilize cellulose and play a role in the breakdown of plant products.
