2578. Peeters, J.F., A.R. Van Rossen, K.A. Heremans and L. Delcambe. 1975. Influence of pesticides on the presence and activity of nitrogenase in Azotobacter vinelandii.. J. Agric. Food Chem., 23(3):404-406.
The influence of various pesticides on the growth of Azotobacter vinelandii was tested under nitrogen fixing conditions. Growth was stimulated in nearly all cases. The presence of nitrogenase in bacterial extracts was greatly reduced. Inhibition experiments showed that organochlorine compounds have no influence on the reduction of acetylene. Derivatives of 2,4-dinitrophenol inhibit in a specific way. A wide range of pesticides were tested.
