Seed cultures behavior upon supplementation of pre-treatment hydrolysate. Seeds were cultivated anaerobically in 3.6 L bioreactor vessels at 55 °C and pH 5.5 in 1 L working volume of molasses-based medium. Relative maximum specific growth rate (μmax,rel(%), red bars) and maximum specific lactate production rate (qlactate (g/(L h OD)), blue bars) are reported for seeds propagated in hydrolysate-free medium (0) as well as in media prepared with 30%, 40%, 50%, 70% and 95% hydrolysate. Relative maximum specific growth rate is reported as percentage of the maximum specific growth rate (h−1) in hydrolysate-free medium
