  1. The potential per polysaccharide was determined by adding up the number of genes per polysaccharide-related (sub-) family.
  2. aIn brackets the numbers including putative GH3 BGLs are given. BGLs are also involved in other processes than cellulose degradation and their high number in the genomes could hide the real difference in gene numbers related to cellulose degradation between the species.
  3. bOnly endoglucanases of this family.
  4. cOnly xyloglucan-active endoglucanases of this family.
  5. dOnly α-xylosidases of this family.
  6. eOnly acetyl xylan esterases of this family.
  7. fOnly β-xylosidases of this family.
  8. gOnly β-xylosidases and α-arabinofuranosidases of this family.
  9. hOnly β-mannosidases of this family.
  10. iOnly endomannanases of this family.
  11. jOnly β-galactosidases of this family.
  12. kOnly endoarabinanases of this family.
  13. lOnly α-galactosidases and α-amylases of this family.
  14. mOnly α-galactosidases of this family.
