Indoor air — Part 22: Detection and quantification of fungal biomass by fungal β-N-acetylhexosaminidase enzyme activity ISO 16000-22:2025

Publication date:   Feb 14, 2025

Scope

This document specifies requirements for the sampling and analysis of air, surface or bulk material samples analysed by fluorometric detection of an enzyme activity present in filamentous fungi[1] (US Patent No. 6,372,446) to quantitatively determine the total fungal biomass density. It describes the analytical procedure that can be performed on-site or in a laboratory. This method does not enumerate or differentiate genera or species of fungi.
