Table 5 Correlations between the relative abundance of microbial taxa and physicochemical parameters during dry co-digestion of food waste and pig manure under the four different operating conditions: (a) Firmicutes and (b) other phyla

From: Exploring the roles of and interactions among microbes in dry co-digestion of food waste and pig manure using high-throughput 16S rRNA gene amplicon sequencing

  1. The relative abundance and physicochemical parameters are the mean of data from the duplicate digesters sampled from R1 to R3, and are the data from the uninhibited digester from R4
  2. Red boxes indicate negative correlations, green boxes indicate positive correlations, and blank boxes indicate no correlations
  3. Correlations were determined using a two-tailed pairwise Spearman’s rank order correlation at a significance level of P < 0.05
  4. P < 0.05; ** P < 0.01
  5. aSCOD: Soluble chemical oxygen demand
  6. bVFA: Volatile fatty acid
  7. cSMY: Specific methane yield
