  1. A reduced quadratic model was used to analyze the data. Factors showing a significant influence on the biomass yield were preselected by automated backward selection with a p-value threshold of 0.100. Factors with a p-value > 0.05 were removed manually, except those needed to maintain the model hierarchy. A p-value of 0.05 indicates a significance (alpha) level of 5%.
