摘要 中英对照阅读
该研究调查了光伏太阳能板适应性及其应用。从印度古吉拉特邦帕坦的光伏太阳能板中提取出嗜热杆菌（KKOHNGU1）。目标是使用E. aurantiacum (KKOHNGU1) 合成并表征银纳米颗粒(AgNPs)，以评估其在环境修复、抗癌和抗菌活性中的潜力。MALDI-TOF 分析确定次级代谢物作为稳定剂和还原剂。AgNPs 使用紫外可见光谱（425 nm 处的峰）、X 射线衍射（27.6°、32.12° 和 46.06° 处的峰）、傅立叶变换红外光谱场发射扫描电子显微镜和能谱仪进行表征，显示出球形结晶AgNPs 的平均尺寸为 121.44 nm。AgNPs（15 mg/mL）表现出抗菌活性，特别是对金黄色葡萄球菌 (S. aureus) 具有 17.5 mm 抑菌圈 MIC（2-32 µg/mL），MBC（32-150 µg/mL）。MTT 实验表明AgNPs 对 MDA-MB-231 乳腺癌细胞系具有抗肿瘤活性，IC50 值为 172.96 µg/mL。比较研究显示细菌和AgNPs 在去除MB染料方面都表现出很高的潜力，在120小时内细菌可以去除73.55%的染料，而AgNPs在10分钟内可去除97.54% 的染料。这些结果表明E. aurantiacum 和 AgNPs 在环境修复中具有潜在的应用价值，特别是在废水处理方面。
