Effect of pH and temperature on microbial community structure and carboxylic acid yield during the acidogenic digestion of duckweed

Table 1 Final volatile fatty acid yields of the blank and active reactors under acidic mesophilic, acidic thermophilic, basic mesophilic, and basic thermophilic conditions

	Acidic mesophilic	Acidic thermophilic	Basic mesophilic	Basic thermophilic
VFA yields (mg VFA as HAc_eq g VS ⁻¹_added )
Blank	218 ± 7.7^a	116 ± 28^ab	256 ± 37^a	86 ± 22^b
Active	55 ± 3.7^a	117 ± 7.9^b	388 ± 28^c	341 ± 2.8^d

Mean VFA yields were compared separately for blank and active groupings using TUKEY test at a significance level of p < 0.05. Superscript letters indicate the resulting statistical groupings within reactor class
