Fig. 3From: Effect of textile dyes on activity and differential regulation of laccase genes from Pleurotus ostreatus grown in submerged fermentationExpression levels of four laccase genes from P. ostreatus during time course fermentation with the addition of acetyl yellow G dye (a) and remazol brilliant blue R dye (b). Error bars represent the standard deviations of the means of three independent amplifications, and asterisks mean that the changes referred to the basal condition are statistically significant at p < 0.05Back to article page
