Have been using the semi-quan API-ZYM test to see the abundantly expressed enzymes by the microbial consortium in a lab-scale Rc treating wastewater. The enzyme "Naphthol-AS-BI-phosphohydrolase" keeps popping out as one of the abundant enzymes, no matter if the feed is synthetic or real wastewater. I cannot find solid info on what this enzyme does. Any idea about that? PS: the substrate of the enzyme in the API-ZYM slot (no12) is "Naphthol-AS-BI-phosphate"
