Biotransformation of sodium lignosulfonates of different molecular weights by the fungus Pleurotus ostreatus.


Fractions of sodium lignosulfonates (NaLS) of varied molecular weight, obtained by gel-permeation chromatography on Sephadex G-50, were exposed to microbiological degradation using liquid cultures of Pleurotus ostreatus. The intensity of transformation observed during 4 weeks of growth (based on nitroso determinations) was inversely proportional to the… (More)
