Fig. 4From: A computational approach to optimising laccase-mediated polyethylene oxidation through carbohydrate-binding module fusion Separation of samples by unsupervised Principal Component Analysis. Principal component analysis was performed within SPSS. Input data were grouped by laccase type into rows and dependent variables as columns. Two principal components were used to discern variance between laccases, grouping similar samples together. Numerical data labels reflect different enzyme variants, reflected within the above legendBack to article page
