Fig. 5From: Identification of diverse antibiotic resistant bacteria in agricultural soil with H218O stable isotope probing combined with high-throughput sequencingHeatmap of selected bacterial OTUs identified in the “heavy” and “light” fractions of DNA extracted from soils incubated with H218O in the presence (AB) or absence (CT) of antibiotics. 18 H-AB-heavy indicates “heavy” fractions treated with antibiotic; 18 H-AB-light indicates “light” fractions treated with antibiotic; 18 H-CT-heavy indicates “heavy” fractions without antibiotic treatment; 18 H-CT-light indicates “light” fractions without antibiotic treatment. The coloured scale represents the relative abundance of the 28 selected OTUs.Back to article page
