Fig. 2From: Co-generation of ethanol and l-lactic acid from corn stalk under a hybrid processKinetic curves of gas stripping of ethanol at different initial ethanol concentrations: a 30.00 g L−1, b 40.00 g L−1, c 50.00 g L−1, d 60.00 g L−1. The error bars in the figure indicate the standard deviations of three parallel replicatesBack to article page
