Despite of broad range application, the cost effective, highly stable and reproduceable synthesis of ZnO is needed, especially which can make it biosafe as well. Here, a unique bioinspired synthesis of ZnO nanoflowers (NFs) has been introduced using Withania coagulans extract as reducing agent. Different molar concentrations were assessed to counter the effect of structural, morphological, antibacterial activity and high efficiency of algae harvesting. The UV-spectroscopy authenticates the synthesis of ZnO NFs having Wurtzite hexagonal structure with the size in the range of 360–550 nm. While surface analysis revealed the presence of stabilizing agent like phenolic, amine, etc. on surface of ZnO NFs. These perineum ZnO NFs exhibited a stronger antibacterial with Gram-positive bacteria Staphylococcus aureus as compare to Gram-negative bacteria Pseudomonas aeruginosa and greater harvesting efficiency up to 94% on the account of greater surface area and unique surface chemistry, thus leading a new horizon of more efficient and effective applications for ethanol production.

尽管应用广泛，但仍需要经济高效，高度稳定且可重现的ZnO合成方法，尤其是使其具有生物安全性的方法。在这里，已经引入了以Withania凝聚物提取物为还原剂的ZnO纳米花（NFs）的独特生物启发性合成方法。评估了不同的摩尔浓度以抵消结构，形态，抗菌活性和藻类收获效率的影响。紫外光谱证实了具有纤锌矿型六方结构的ZnO NF的合成，其尺寸在360-550 nm范围内。表面分析表明，ZnO NFs表面存在稳定剂，如酚，胺等。这些会阴部ZnO NFs对革兰氏阳性细菌表现出较强的抗菌作用与革兰氏阴性细菌铜绿假单胞菌相比，金黄色葡萄球菌的捕获效率高达94％，这是因为表面积和独特的表面化学性质所致，从而开创了乙醇生产更高效应用的新视野。
