  • Fungal attack on coal II. Solubilization of low-rank coal ...

    The solubilization of low-rank coal by fungi is not accompanied by its depolymerization, which was proven by several screening programs. A total number of 728 fungal strains were yet tested for solubilizing a German low-rank coal (lignite). The coal were used oxidatively pretreated (3% H 2 O 2) and natively. During the first screening, the nitrogen content of the media were reduced to select ...
