SEM of the anaerobic fungus N. frontalis YakQH5. A The mycelium of the N. frontalis YakQH5 penetrated into the thick-walled tissue of wheat straw after 24 h incubation. B The N. frontalis YakQH5 grew with an endogenous sporangium growth after 48 h incubation. C The dense hyphae of the N. frontalis YakQH5 fully penetrated into the wheat straw tissue to physically degrade lignocellulose after 96 h incubation. Bars = 20 μm
