Rapid cost-effective analysis of microbial activity in soils using modified fluorescein diacetate method

Schumacher, Thomas E. | Eynard, Anna | Chintala, Rajesh
Fluorescein diacetate (FDA) is commonly used to determine the hydrolyzing activity of microbial organisms in the soil. However, the costs of chemical reagents and time required to perform routine analysis of large number of samples by soil testing laboratories are limiting. Moreover, existing methods generate significant volumes of hazardous waste. In this context, this study was designed to determine the minimum amount of terminating chemical reagent needed to evaluate microbial hydrolyzing activity. The results showed that 0.2 mL of chloroform was enough to effectively stop the hydrolyzing activity in soil. This proposed terminating chemical reagent (0.2 mL chloroform) was also evaluated by comparing with the 10 mL of chloroform and 5 mL of methanol used in the Adam and Duncan method.
