AB  - Microorganisms  play  an  important  role  in  the  treatment  of  pollutants  in  the
environment such as glyphosate. Thus,
the study and 
scientific knowledge of these 
are
essential for improving the living conditions of the different 
ecosystems. In this 
work,  different  consortia  of  bacteria,  from  two  cryopreserved  samples,  were 
isolated  in  which  there  were  bacteria  with  poten
tial  degrading  glyphosate.  One 
called  (M1C),  where  the  herbicide  is  used  as  a  carbon  source  and  the  other  one 
called  (M2F)  that  was  used  as  a  source  of  phosphorus,  at  a  concentration  of  the 
selective means of 6 g/L of glyphosate and then it would be able t
o determine their 
degrading  capacity.  Furthermore,  in  this  study,  it  was  possible  to  determine  the 
effect  of  glyphosate,  in  different  amounts  (
10  mg,  100  mg  and  1000  mg),  on 
bacterial  communities  in  a  sample  of  fertile  soil,  in  which 
it  was  found  that  this
chemical  has  significant  effects  on  the  growth  of  bacteria.  On  the other  hand,  the 
degrading  capacity  was  evaluated  on  a  laboratory  scale  for  seven  days,  using 
HPLC technique coupled with UV. Treatment (M1C) removed approximately 54.50 
% while treatment (
M2F) removed approximately 66.05 %.
