This patent describes a method for isolating an extracellular product derived from a broth of Coriolus versicolor. It comprises separating the cells from a broth of C. versicolor to obtain a cell-free filtrate; separating from the cell-free filtrate a fraction containing molecules of molecular weight in the range of about 500 to 1000 daltons. This patent also describes a method for degrading low-rank coal to a water-soluble material. It comprises contacting the low-rank coal with a cell-free fraction from the broth of Coriolus versicolor containing molecules in the molecular weight range of about 500 to 1000 daltons.
