應用
4-硝基苯基β-D-吡喃木糖苷已用作底物，以测定β-D-纤维二糖苷酶或纤维二糖水解酶（胞外纤维素酶）在微生物群落中的活性。它还可用作底物来研究内切葡聚糖酶J30的活性。
生化／生理作用
4-硝基苯基 β-D-吡喃木糖苷是一种纤维三糖类似物，和常用于检测纤维素酶活性的显色底物。外切葡聚糖酶、内切葡聚糖酶和β -葡糖苷酶可水解4-硝基苯基 β-D-吡喃木糖苷，以形成p-硝基酚（PNP）。

An enzyme active against p-nitrophenyl-beta-D-glucoside was purified from logarithmic-phase cells of Ruminococcus albus cultivated in a medium containing ball-milled cellulose. The purification yielded homogeneous enzyme after an approximately 520-fold increase in specific activity and a 9% yield. The enzyme was
