Organization: ISO
Publication Date: 1 February 2019
Status: active
Page Count: 16
ICS Code (Biological properties of soils): 13.080.30
scope:

This document specifies a method for determining activity of dehydrogenases in soil, using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT)[1]-[5]. As the INT reduction is less sensitive to O2, the method is more robust than the TTC-method described in ISO 23753-1.
