本发明属于生物工程技术领域，具体公开一种镰刀菌菌株及其应用。通过ITS基因序列鉴定为镰刀菌Fusarium sp.其保藏编号为CCTCC M 2016582。本发明利用失活FP‑JCCW菌体研究其对铊的吸附行为，得出最佳吸附条件：pH5.0，初始浓度100mg/L，接触时间90min，转速150r/min，生物量2.5g/L。且其吸附更符合Langmuir等温模型和二级动力学方程，为单分子层吸附，以化学吸附为主。FT‑IR、SEM、XRD表征分析显示，FP‑JCCW表面多孔隙，其对铊的吸附主要依靠细胞壁上的羟基、羰基等，且吸附前后菌体晶体结构发生变化。由此推断，失活微生物菌体FP‑JCCW吸附铊是通过静电吸附和表面络合完成。本发明提供的失活微生物FP‑JCCW可作为经济环保、可持续性的吸附剂处理重金属铊污染。
