Expression of carbohydrate metabolism marker genes in a batch culture (A) and a fed-batch culture (B) of T. reesei. Lactose concentration, Feed rate of lactose rfeed (mg lactose h-1 g-1 DW), mRNA expression levels of acs1, gpd1 and eno1 relative to expression level measured in the first sample (19.2 h). Expression levels were normalised using polyA RNA.
