Expression of oxygen sensitive hem6, hsp70 and trx2 genes in different cultures of T. reesei. Expression of hem6, hsp70 and trx2 genes (A) during batch culture of T. reesei compared with DO and biomass concentration and (B) maximal expression levels of hem6, hsp70 and trx2 measured in an anaerobic culture (AnA, DW 4 g l-1, pO2~0%), steady state with high cell density (SS-HD, DW 16 g l-1, pO2 ~30%) and with low cell density (SS-LD, DW 4 g l-1, pO2 ~80%), in batch cultures with high cell density (B-HD, DW 20 g l-1, pO2 ~30%) and in shake flask precultures (SF, DW ~2 g l-1). Error bars show the standard deviation between triplicate cultures.
