Details on CAZy families are available in Supplementary Table 11. Growth profiles are available in Supplementary Fig. 6. All black aspergilli grew well on pectin and have a highly conserved and extensive set of genes encoding pectin-active enzymes. Growth on other plant polysaccharides such as xylan, starch, and guar gum was more variable, despite the presence of highly conserved genes related to xyloglucan and starch degradation. The growth and genetic variability on inulin are particularly high: nine species showed reduced growth. Moreover, endoinulinase (GH32 INU) is only present in eight of the black aspergilli, while the remainder of inulin-related genes (GH32 INV and INX) are more commonly present (Supplementary Table 11). However, the growth phenotypes show no correlation with the gene content (Supplementary Fig. 6).
