Metadata analysis on enzyme production by T. reesei on insoluble substrates. Depicted is the correlation between the substrate concentration and the FPA (a), the protein concentration and the FPA (b), and the hemicellulose content of the substrate and the xylanase activity (c). Data are summarized in Additional file 1: Table S1. The solid line represents the linear regression of the data points, the dotted line the 95% confidence interval
