  1. aSubstrate loading units are mg/g DM.- indicates no mycelium growth on the CS; + indicates the fungal mycelium was observable but minimal; ++ indicates the fungal mycelium grew quickly and covered the surface of the solids medium of the flask. Thoroughly washed dilute acid-pretreated CS with fungal inocula in the flasks was cultured at 25°C for 9 days in the static incubator.
