Using Halophiles (Bacillus pumilus) to treat spinetoram (pesticide) Contamination

Abstract

Pesticides can be define as any substance or mixture of substances, which used to control damaging pests such as insects, When  pesticides applied, the impacts begin to appear on human, plants, or animals, these toxic compounds (pesticides) have been engaged in various disorders and diseases including cancer In this study, new strain of bacillus species were identification in Iraqi environments and test their ability to degrade the pesticides that was used usually in agricultural fields. The samples taken from agricultures areas in Al-Zubaydiya, Wasit Governorate and cultured on agar, three temperatures 25, 30, and 35 °C were chosen. Also, three pH values of 5, 7, and 9 for this purpose, three concentrations of spinetoram pesticide 600, 1200, and 1800 ppm were used. The results at a temperature of 35 ° and pH 9 and 7 were the optimum conditions with removal ratios of 99 %, 97 % or 94 % respectively at 600 ppm of spinetoram
