Abstract
The phenolic compounds produced by Pseudomonas acidovorans interacted with the herbicide Venzar changing its phytotoxicity. Bioassay with Chlorella vulgaris and lettuce showed that the interaction of the bacterial phenols and Venzar was synergistic or antagonistic depending on the concentration of the phenolic compounds its chemical structure and pH of the environment. The humic-like polymers isolated from the bacterial culture reduced to a small extent the phytotoxicity of Venzar. It was found that [C14]-labelled Venzer was incorporated into the bacterial humic-like compounds due to the action of the enzymatic system of the bacteria.
