Abstract
The effect of fertilizers activators on bacteria and actinomycetes growth and capability in degrading α and β- endosulfan was studied by incubating bacteria and actinomycetes which live in poor media in the presence and absence of four fertilizers (urea , triple super phosphate , urea + triple super phosphate
and cow manure) for 45 days with sample drown every 15 days. Drawn sample were examined for microbial growth, concentration of starting material remained and a mount of endosulfan sulphate generated. Results indicated that all activators caused significant increase in microbial counts especially the triple super phosphate followed by urea + triple super phosphate, cow manure and urea. Significant reduction in half lives of α and β- endosulfan accompanied with various level of sulphate generation was noticed. The great potential shown by bacteria and actinomycetes in degrading endosulfan could similarly promote their capability in degrading ndosulfan in soil.
