Table 2 Metabolic flux ratios of T. reesei wild type (wt) and Δcre1 strains in aerobic batch cultures on glucose and on sorbitol with and without sophorose induction of cellulase gene expression.

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
