Abstract: The nitrogen-modified lignocelluloses (NML) produced under oxic ammoniation was metabolized by white rot fungus, NH_{4}^{+}–N was released, NO_{3}^{−}–N concentration was decreased and total nitrogen loss was blocked within incubation period. During releasing nitrogen from the metabolism of NML, white rot fungus cometabolized recalcitrant environmental pollutants and showed higher degradation capability. Results indicated that this NML complex colonized by white rot fungus might be effective with economic feasibility when they are applied into the vast field ecosystem, it might stabilize NH4+ nitrogen flux and bioremediate the polluted environmental sites.
Keywords: white rot fungus, ammoniated lignin, cometabolism, pollutants
