ISO/TS 22939-2019 土壤質(zhì)量--在微孔板上用熒光底物測量土壤樣品中的酶活性模式 Soil quality -- Measurement of enzyme activity patterns in soil samples using fluorogenic substrates in micro-well plates

This document specifies a method for the measurement of several enzyme activities (arylsulfatase, α −glucosidase, β -glucosidase, Cellubisidase, β -Xylosidase, phosphodiesterase (PDE), chitinase, phosphomonoesterase (PME), leucine-aminopeptidase, Alanine-aminopeptidase) simultaneously (or not) using fluorigenic substrates in soil samples. Enzyme activities of soil vary seasonally and depend on the chemical, physical and biological characteristics of soil. Its application for the detection of harmful effects of toxic chemicals or other anthropogenic impacts depends on the simultaneous comparison of enzyme activities in a control soil similar to the test soil, or on exposure tests with chemicals or treatments.nd edition 2019-08 Soil quality — Measurement of enzyme activity patterns in soil samples using fluorogenic substrates in micro-well plates Qualité du sol — Mesure en microplaques de l'activité enzymatique dans des échantillons de sol en utilisant des substrats fluorogènes Reference number ISO/TS 22939:2019(E) ？ ISO 2019 ISO/TS 22939:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO
