  1. Models illustrate which cell wall factors had a significant influence on the saccharification yield or pretreatment effect. The “parameter estimate” indicates the increase in saccharification yield or pretreatment effect when 1 unit of the cell wall factor is increased when the other cell wall factors are fixed. The standardized estimate indicates the strength of the influence on the saccharification yield or pretreatment effect. Lignin2 = lignin x lignin. All data used to build these models can be found in Additional file 4.
