Table 1.

Parametric estimations corresponding to hydrolysis data modelling by Weibull equation of the experimental conditions studied (Table S1). Independent variables are expressed in natural values in brackets. Numerical values of the parameters are shown with their confident intervals. Determination coefficients (R2) and p-values from Fisher F-test are also summarized. NHD: non hydrolysis detected.
