Potential hydrolytic enzyme activitiy (β-glucosidase) of topsoils in alley cropping systems at different distances of trees

Potential hydrolytic enzyme activities were analysed according to Marx et al. (2001) with the fluorescently labelled substrate based on 4-MUF-β-D glucopyranoside. The enzyme contributes to the degradation of cellulose.

Soil samples were sampled in 0-5 cm in October/November 2015

Research domain: Soil Sciences

Research question: Spatial distribution of soil quality indicators in topsoils at three German silvo-arable ACS and effect of distance of trees and soil abiotic parameters on microbial soil properties.

本研究依照Marx等人（2001）的方法，采用基于4-甲基伞形酮-β-D-吡喃葡萄糖苷（4-MUF-β-D glucopyranoside）的荧光标记底物，对潜在水解酶活性进行了分析。该酶可参与纤维素的降解过程。
