Role of light intensity in the E-AAS system under aniline stress
In this section, 16S rRNA and 18S rRNA high-throughput sequencing was performed on three sets of sludge samples at the end of the systematic test, named as follows: w0 (domesticated bacterial-algal symbiotic sludge); A1 (mixed sludge A1_1, cathodic biofilm A1_2, anodic biofilm A1_3); A2 (mixed sludge A2_1, cathodic biofilm A2_2, anodic biofilm A2_3) and A3 (mixed sludge A3_1, cathodic biofilm A3_2, anodic biofilm A3_3).
