Butachlor is a chloroacetamide herbicide used worldwide for controlling weeds in plants of rice, corn, soybean and other crops. In this study, indigenous bacterial species sp. JF was isolated from the agricultural fields of Punjab and identified using 16S ribosomal RNA analysis. The bacteria utilized butachlor as the sole carbon source and showed complete degradation (100 mg/L) within 24 h of incubation. Two intermediate products, namely 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester and 2,4-bis(1,1-dimethylethyl)-phenol were observed at the end of butachlor degradation. To the best of author's knowledge, biodegradation of butachlor by indigenous sp. JF from the agricultural fields of Punjab has not been reported so far.
丁草胺是一种氯乙酰胺类除草剂，在全球范围内用于控制水稻、玉米、大豆和其他作物中的杂草。在本研究中，从旁遮普邦的农田中分离出本地细菌菌株JF，并通过16S核糖体RNA分析进行鉴定。该细菌利用丁草胺作为唯一碳源，在培养24小时内显示出完全降解（100毫克/升）。在丁草胺降解结束时观察到两种中间产物，即1,2-苯二甲酸双(2-甲基丙基)酯和2,4-双(1,1-二甲基乙基)苯酚。据作者所知，旁遮普邦农田中本地菌株JF对丁草胺的生物降解迄今尚未见报道。
