Soil Sample Preservation Strategy Affects the Microbial Community Structure.

ABSTRACT: Sample preservation is a critical procedure in any research that relies on molecular tools and is conducted in remote areas. Sample preservation options include low and room temperature storage, which require freezing equipment and specific buffering solutions, respectively. The aim of the present study was to investigate whether DNA/RNA Shield 1x from Zymo Research and DESS (Dimethyl sulfoxide, Ethylenediamine tetraacetic acid, Saturated Salt) solution performed similarly to snap freezing in liquid nitrogen. Soil samples were stored for 1 month in each of the buffers and without any solution at a range of temperatures: -20, +4, and +23°C. All treatments were compared to the "optimal treatment", namely, snap freezing in liquid nitrogen. The quality and quantity of DNA were analyzed, and th
