Fig. 5From: Combining manipulation of transcription factors and overexpression of the target genes to enhance lignocellulolytic enzyme production in Penicillium oxalicum Analysis of the driving efficiencies of four promoters. a–d Transcriptional levels of four genes in wild-type strain were measured on glucose and cellulose. Error bars represent the standard deviations. e, f Phenotype observations of clrB overexpression strains and clrB double overexpression strains on cellulose platesBack to article page
