印度近30%的宝贵农业产出因虫害而损失。在印度，用于保护作物的农药消费量约占世界总消费量的3%。单效磷（MCP）是一种有机磷杀虫剂，被广泛用于防治作物害虫。由于其易溶于水且剧毒，因此必须从生产过程中产生的废水中去除。pH值为8.0时，atrocyanarthrobacterium、megaterium芽孢杆菌和mendocin假单胞菌对含MCP废水的生物修复效果最好，而pH值为7.0时，化学需氧量（COD）的降幅最大。MCP的去除和COD的降低。megateriumandPs。在35°C时，mendocina最高；在30℃，曝气培养条件下，接种密度为108个细胞/ml， atrocyaneus在此条件下最大。使用纯培养物对含有MCP的废水进行生物修复似乎是第一次这样的尝试。
Almost 30% of the precious agricultural output of India is lost owing to pest infestation. In India, pesticide consumption for protecting crops is about 3% of the total world consumption. Monocrotophos (MCP), an organophosphorus insecticide, is widely used to control insects on crops. Being readily water soluble and highly toxic, its removal from wastewater generated during manufacture becomes inevitable. Bioremediation of wastewater containing MCP byArthrobacter atrocyaneus,Bacillus megaterium, andPseudomonas mendocinawas highest at pH 8.0, but maximum reduction in Chemical Oxygen Demand (COD) was at pH 7.0. Removal of MCP and reduction in COD byB. megateriumandPs. mendocinawere highest at 35°C, while withA. atrocyaneus, it was maximum at 30°C, under aerated culture condition and inoculum density of 108cells/ml. Use of pure cultures for bioremediation of effluent containing MCP appears to be the first such attempt.
