Abstract:Summary Production of lysine and methionine byAzotobacter chroococcum strain H23 andA. vinelandii strain ATCC 12837 was studied in chemically-defined medium and dialysed-soil medium, amended with different concentrations of Simazine. Responses on production due to Simazine were different for each strain and were fairly conditioned by culture media composition. Quantitative production of amino acids was significantly affected by the xenobiotic only at higher doses (50–100,mgrg/ml). The effect of Simazine on methionine production by strain H23 was very pronounced when bacteria were grown in dialysed-soil medium, which was specially formulated to reproduce the natural habitat of the organisms.
Keywords:Amino acids  Lysine  Methionine  Azotobacter  Simazine
