File Name : fig s1.tiff

Caption : fig. s1 mechanism underlying reversible glycosylation to form β-1,2 and β-1,6 glycosidic bonds catalyzed by acid.

File Name : fig s3.tiff

Caption : fig. s3 the number of differentially expressed genes (degs) of samples using acsm, lactose, and microcrystalline cellulose (mcc) as the inducer by referring to the sample using glucose (a), and the main classification of these degs were represented by the bubble plot through gene ontology (go) enrichment analysis (b).

File Name : fig s4.tiff

Caption : fig. s4 expression profiles of genes encoding carbohydrate-active enzymes (cazymes). a: expression of genes encoding cellulases and xylanases in <i>t. reesei</i> rut-c30 cultivated by different carbon sources; b: overview of genes expression in each glycolic hydrolase (gh) family. 

File Name : fig s5.tiff

Caption : fig. s5 comparison between the cost of different inducers. the price of lactose and microcrystalline cellulose (mcc) was referred to the bulk supplier and the production cost of acsm was simulated by aspen plus.
