In this paper, the authors found the pyritized rod-like bacteria in desmocollinite and the Cyanophytes's gelationous sheath and the degraded organic matter of blue green algae in collinite of high-sulfur coal seams No.9 w(So=2.67% and No.10 w(So=2.54% using SEM-EDX and TEM. These findings of bacteria and algae suggest that they play an important role in the high-sulfur formation.
