The values are given as mean of three independent biological replicates, and bearing different letters (a, b, c) are significantly different from each other according to the LSD test (p < 0.05). The bars represent the standard error. SAP: Super Absorbent Polymer, BJ-18: P. beijingensis strain BJ-18, L-56: Bacillus sp. strain L-56, pNP: p-Nitrophenol, TPF: Triphenylformazan.
