Figure 2From: Effects of apples and specific apple components on the cecal environment of conventional rats: role of apple pectinPCA analysis of samples from Experiment B. Principal Component Analysis of DGGE profiles of bacterial rRNA genes present in fecal samples from rat fed with control diet (red) or pectin diet (green), respectively. A: Pectin in diet constituted 3.3%. The amount of variability accounted for by Factor X is 25.5%, by Factor Y 19.6% and by Factor Z 13.8%. B: Pectin in diet constituted 0.33%. The amount of variability accounted for by Factor X is 36.4%, by Factor Y 22.1%, and by Factor Z 10.7%.Back to article page
