Microbial volatile fingerprints: potential use for soil/water diagnostics and correlation with traditional microbial parameters [PDF]
This project used an electronic nose (E-nose) system composed of an array of 14 nonspecific conducting polymer sensors for soil and water diagnostics, based on qualitative microbial volatile production patterns. It tested the feasibility of using soil
