F.  aSelection of microorganisms degrading S-Metolachlor herbicide.  c2007  aThe aim of this work was to study herbicide degradation through selected microorganisms from humus and soil subjected to different plantation systems. The following bacterial species were identified: Klebsiella pneumoniae pneumoniae GC s.B strain 1, Pseudomonas alcaligenes, Enterobacter aerogenes GC s.A and Klebsiella pneumoniae pneumoniae GC s.B strain 2. Growth studies yet suggested the possibility of a very long lag phase. Although, culture with the herbicide presented biofilm formation and there were color changes in the herbicide that could have interfered with the espectrophotometry readings. After 5 days of incubation at 35ºC, the difference in the concentration of herbicide was 14.42% on average and after 10 days, 35.01%.  aEnterobacter aerogenes  aPseudomonas alcaligenes  aBactéria  aBiodegradação  aHerbicida  aKlebsiella Pneumoniae1 aMARTINEZ, C.
