Fig 2. Yields of single stranded extracellular DNA (eDNAss) and double stranded extracellular DNA (eDNAds) expressed as eDNA (μg/g dry soil) extracted by using sterile water (ddH2O) and alkaline Sodium phosphate buffer (NaP) for different durations (hours) (NaPI = 2h, NaPII = 4h, NaPIII = 8h, NaPIV = 12h).

Bars represent mean values with standard errors (n = 3); the letter indicates significant differences between ss and ds DNA concentrations. Further two-way ANOVA was performed to assess the effects of the extraction method (EM), DNA form (DF) and their interactions.
