Fig. 5From: Characterization of thermophilic fungi producing extracellular lignocellulolytic enzymes for lignocellulosic hydrolysis under solid-state fermentationDetection of laccase enzyme activity from the isolated fungal strain on agar plates. The appearance of the reddish brown zone around the colony indicates as a laccase-producing fungal strain on the 7th day. a Plate without guaiacol; b plate with guaiacol as a substrateBack to article page
