NLM Int J Environ Res Public Health. NIH N-Allylthiourea was used as nitrification inhibitor in a study on transformation of diclofenac, naproxen and bisoprolol under aerobic and anaerobic conditions. The inhibition of nitrification by thiourea was studied in a clay soil under spring barley. The OUR of the activated sludge is determined initially and then, when a specific inhibitor of the nitrifying bacteria has been added (i.e. The effect of thiourea on the germination of lettuce was first described by Thompson and Kosar (1939) and its interaction with light was studied by Evenari et al. The dominant thiourea-degrading bacteria strain that used thiourea as the sole carbon and nitrogen source in the sludge system was identified as Pseudomonas sp. Effects of the inhibitors dicyandiamide (DCD), nitrapyrin (N-Serve, NS), and thiourea (TU) on growth and metabolism ofNitrosomonas europaea were tested under laboratory conditions. Both in lettuce and endive, thiourea abolished the inhibitory effect of high temperature; in lettuce thiourea also abolished the light requirements of the seeds.
