Fig. 4From: Production of a high-efficiency cellulase complex via β-glucosidase engineering in Penicillium oxalicum qPCR analysis the transcription levels of the BGL(X) gene in the corresponding mutants. The transcription level of bgl1 (a), bgl4 (b), and bgl5 (c)were determined at the 4 or 22 h for cellulose induction or at 4 h for the culture on glucose. The means of three biological replicates was showed and the error bars indicated the standard deviationBack to article page
