Most microorganisms range from one to three microns in diameter with ultramicrobacteria being less than 0.3 microns in diameter. Thus, microorganisms would generally be able to fit into the cleat spaces of coals. This indicates that bacteria can be injected into coal reservoirs with small cleat aperture size and be able to access the coal.
