Effects of diquat on the microbiological organisms in the soil of lakes
Proceedings of the Pollution Research Conference June 1973 Wairakei, New Zealand DSIR Information Series 97: 529-538
fixation measured by the acetylene reduction technique revealed that light was not an essential factor in the inhibition of N fixation by diquat. The herbicide did not inhibit protein breakdown or the reduction of NO3 to NO2. However, it did inhibit the formation of NO3 from NH3 by Nitrosomonas and the reduction of NO3 to NH3 by Desulfovibrio. A member of the genus Achromobacter isolated from the sediment was capable of reducing diquat.
