Fluorescence in situ hybridization (FISH) is a widely used molecular technique in microbial ecology. However, the non-specific adsorption of fluorescent probes and resulting high intensity of background signals from mineral particles hampers the specific detection of microbial cells in grain-rich environmental samples, such as subseafloor sediments. We herein demonstrated that a new buffer composition containing EDTA efficiently reduced the adsorption of probes without compromising the properties of the FISH-based probing of microbes. The inclusion of a high concentration of EDTA in the buffer in our protocol provides a simple and effective approach for reducing the background in FISH for environmental samples.
