Figure 2. Transcriptional levels of A. niger glycoside hydrolases: 24 h time course on different carbon sources.

(A) Endo-PGs and endo-XGH. (B) Exo-acting hydrolases. Minor axis intervals, time points of harvesting after transfer from fructose (in h); 0′–18 h preculture on 2% (w/v) fructose; White colour indicates absent call. The numeric values and calls from the obtained expression data are provided as Supplementary Table 1 (http://www.BiochemJ.org/bj/400/bj4000043add.htm).
