Changes in enzyme activity (a) and bacterial abundance (b) during straw decomposition. Different lower letters at the top of the columns present significant differences among decomposition periods (P < 0.05). BG, CB, XYL, NAG, and LAP are β-glucosidase, β-cellobiohydrolase, β-xylosidase, β-N-acetylglucosaminidase, and Leucine aminopeptidase activities, respectively.
