Abstract
The effects of 10, 50, 100, 200 and 300 mu g ml-1 of bromopropylate and methidathion were investigated in the cells of Azospirillum brasilense grown in chemically defined media and dialysed-soil media. The insecticide bromopropylate did not affect microbial growth, the levels of ATP and dinitrogen fixation of A. brasilense in either chemically defined media or dialysed-soil media. Methidathion significantly reduced dinitrogen fixation, the intracellular levels of ATP and growth in cells grown in chemically defined media. However, these negative effects were not significant in cells grown in dialysed-soil media, showing that A. brasilense can tolerate high concentrations (300 mu g ml-1) of methidathion under the present experiment conditions
