Abstract
In recent years, microbiome research has risen significantly,as it provides important insights into our health. Microbial analyses are inflenced by many factors, inter alia sample processing. DNA extraction plays an important role in this process, as adequate DNA quantity and quality are essential for successful and complete microbial analysis. Here, it is focused particularly on the different DNA extraction methods for the subsequent characterization and DNA sequencing of the intestinal microbiome of rainbow trout (Oncorhynchus mykiss).
