Figure 1. Kinetics of cellobiohydrolase (CBH) production in shake flask fermentation of four representative substrates. The initial pH of the medium was 7.3, inoculum size 10 %, on 1% (w/v) carbohydrates in substrates, and temperature 30ºC. ο = CBH, Δ = cell mass, and ٱ = substrate present in the fermentation medium. Error bars show standard deviation among three replicates.
