The shape of the response surface curves showed a moderate interaction between these tested variables.
The assumption of normal distribution of tested variables was assessed with the Shapiro Wilk test.
The shape of the response surface curves showed strong positive interaction between these tested variables.
The tested variables included leaf area index (LAI), number, diameter, length and production of stems.
Mathematical methods were used to describe dependencies between the tested variables.
All the tested variables were identified to have significant effects (p < 0.05) on fermentable sugars recovery.
These surface plots provide a method to predict the decolorization efficiency for different values of the tested variables.
For GYO651 all tested variables depend significantly from competition, this is not the case for ING650 and SAN653.
Open image in new window Fig. 16 Perturbation plot showing the effect of the tested variables on breakthrough time.
The tested variables included cell concentration, post-induction temperature, inducer concentration and post-induction period for cell harvest.
These surface plots provide a method to predict the biosorption efficiency for different values of the tested variables.
