Standardizing microbiome research: interlaboratory validation of SOPs for sample preparation and DNA extraction from food and environmental ecosystems.

ABSTRACT:

Background

Microbiome research has expanded rapidly, however, lack of standardized and validated protocols for microbiome sampling and DNA extraction has hindered the reproducibility and comparability of studies. The SUS-MIRRI.IT project aimed to prepare and validate Standard Operating Procedures (SOPs) for microbiome analysis across diverse ecosystems, including fermented foods, soils, waters, and more. To validate these protocols, 15 Italian research units (RUs) participated in an interlaboratory trial on 120 samples (liquid and solid fermented foods, waters, and soils). Metataxonomic sequencing was performed using 16S rRNA gene amplicon sequencing to assess the reproducibility of the protocols. The interlaboratory trial involved distributing homogenized samples to participating
