Fig. 2

The normalized signal intensity of the detected key genes involved in carbon degradation. The complexity of carbon is presented in order from labile to recalcitrant. The signal intensity for each functional gene category is the average of the total signal intensity from all the replicates (n = 8). All data are presented as mean ± SE (error bars). Different letters indicated statistical differences at a P value of < 0.05 among sampling sites by one-way ANOVA
