Alkalilignin samples obtained from untreated paper-mill effluent and eftluent decolorized by Streptomyces UAH 30 and Streptomyces UAH 51 were analyzed by pyrolysidgas chromatography/mass spectrometry. The molecular composition of the samples and the chemical modifications occurring in the lignin uni

Pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) was applied in order to monitor the extent of chemical modification of lignin units after seven-day treatment of paper-industry wastewaters using two ligninolytic fungi. Py-GC-MS after the effluent treatment with Ganoderma austrule revealed a
