The Great Microbiome Extraction Anomaly: How Extraction Bias Distorts Microbial Community Profiles

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Specimen chemistry and nucleic acid state (intracellular, host‐associated, adsorbed, extracellular) influence recovery. Extraction efficiency varies by microbial biology (e.g., reduced lysis of Gram‐positive bacteria). Even under consistent protocols, these factors systematically distort measured community composition relative to the true microbiome ...

Differentiation of Micrococcus luteus and Micrococcus varians on the Basis of Catalase Isoenzymes [PDF]

Journal of General Microbiology, 1976
Crude extracts prepared from four Micrococcus varians strains, 11 M. luteus strains and four laboratory isolates subsequently classified with M. luteus were assayed for catalase activity following electrophoresis on polyacrylamide gels. The enzyme patterns produced from the M. varians strains exhibited three catalase isoenzymes which were distinguished
