The glycoside conjugation of alcohol, ROH, yields RO-glucuronic acid. Carboxylic acids, RCOOH, become RCOO-glucuronic acid. Conjugated amines, RNH2, yield RNH-glucuronic acid. Sulfate conjugation uses phenol sulfotransferase to break down phenol but not steroids: ArOH → ArOSO3H. Alcohol sulfotransferase, enhanced by the activity of other sulfotransferases, catalyzes alcohol and polyol, ROH, synthesis to ROSO3H.

The main bacterial genera related to EtOH conversion to acetic acid were Clostridium (0.02% to 0.08%), Escherichia (0.79% to 0.12%) and Pseudomonas (1.16% to 5.06%), for conditions containing NPE and control, respectively [74, 75, 76]. It should be noted that NPE recalcitrance increases with the decrease in the number of ethoxylate groups [10, 77], resulting in more toxic, persistent and bioaccumulative metabolites, such as 4-NP and NPE1. 4-NP can be used as a substrate for the reaction catalyzed by the enzyme alcohol sulfotransferase, in the steroid hormone biosynthesis, and is, therefore, considered an endocrine disruptor [18]. However, there are few reports in the literature on the anaerobic biodegradation of 4-NP, and its metabolic pathway for degradation is still poorly understood.
