For instance, when exposed to a combination of MAP and S-200, NodB genes in CANT-HYD showed a trend similar to that of nahAa and nahAb (naphthalene 1,2-dioxygenase) predicted by PICRUSt2, with a slight decrease in abundance compared to the oil-only group (p < 0.05, one-way ANOVA; p < 0.05, t-test).
