This result supports the hypothesis that atrazine was degraded as a source of nitrogen.
Their value as a source of nitrogen, particularly that of the legumes, is unquestioned for certain crops such as potatoes, cotton, and corn (maize); for other crops, such as peanuts (groundnuts; themselves legumes), the practice is questionable.
Under these nitrogen-limiting conditions it was hypothesized that bacteria capable of using atrazine as a source of nitrogen would remove atrazine from the flowing water.
Here we report a facile hydrothermal process using ammonia as a source of nitrogen (N) and thiourea as a sulfur (S) source to prepare N/S co-doped three dimensional (3D) graphene hydrogel (N/S-3DGH) for supercapacitor electrode application.
The concentration of OMW (A) (i.e., 20%, 30 % and 40), concentration of ammonium sulfate as a source of nitrogen (B) (i.e., 0.25, 0.5 and 0.75 g/l) and glucose as a carbon source (C) (i.e., 3, 5 and 7 g/l), both of which used for the fungus growth, were considered as independent variables.
The results showed that visible-light photocatalytic activity of TiO2 was extremely increased through adding thiourea (Tu) as a source of nitrogen and sulfur into TiO2 sol, which conducted to degradation of MO solution up to 95% in sunlight irradiation after only 2 h.

Another nutrient that is a potential source for H2S formation is the tripeptide glutathione (GSH) (Hallinan et al. 1999; Rauhut 2008; Sohn and Kuriyama 2001; Vos and Gray 1979), which can also serve as a source of organic nitrogen (Mehdi and Penninckx 1997).
