Mechanical lysis in sterile synthetic soil microcosms yields 2.0-fold more DNA from adherent Agrobacterium tumefaciens than from non-adherent cells, supporting an anvil effect during bead-beating.
- Why it matters: DNA extraction bias is often modeled as intrinsic to cells, but surface-attached microbes may be physically stressed differently during lysis, risking misestimation of community composition.
- What they did: Isogenic strain pairs differing in adhesion were tested in standardized, aggregate-free synthetic soil, comparing the DNA yield ratio from mechanical versus chemical lysis between adherent and non-adherent strains.
- The result: Mechanical lysis favored adherent cells, with bias also altered by how soil was transferred to lysis tubes, implying physical context can change extraction efficiency beyond fixed strain coefficients.
