Table 3 Metabolic flux ratios of T. reesei wild type (wt) and Δcre1 strains in compared with the corresponding flux ratios observed in the crabtree positive and negative yeasts S. cerevisiae and P. stipitis [26, 27].

From: 13C-metabolic flux ratio and novel carbon path analyses confirmed that Trichoderma reesei uses primarily the respirative pathway also on the preferred carbon source glucose
