开发合适的应用工艺,扩大微生物合成纳米材料的规模,是未来可持续工业生产的一个诱人的新兴前景。本文对内生细菌A.terreus ORG-1提高Co3O4、CuO、Fe3O4、NiO和氧化锌纳米颗粒产量的发酵条件进行了优化研究。对不同的栽培条件进行了评价。然后,使用响应面方法程序来优化控制这些NPs生物合成的物理条件。最后,采用了伽马辐照的方法来提高纳米粒子的产量。在最佳条件下,经过伽马辐照后,最终产量分别达到545.71,651.67,463.19,954.88,1356.42 mg L−1。据我们所知,这是首次报道从一个微生物培养物生产和增强不同类型的纳米材料,这将为纳米材料的微生物生产的产业化开辟道路。
Developing a suitable applicative process and scaling up the microbial synthesis of nanomaterials is an attractive and emerging prospect for a future sustainable industrial production. In this paper, optimization of fermentation conditions for enhanced production of Co3O4, CuO, Fe3O4, NiO, and ZnO nanoparticles by the endophytic A. terreus ORG-1 was studied. Different cultivation conditions were evaluated. Then, a response surface methodology program was used to optimize physical conditions controlling the biosynthesis of these NPs. Finally, the use of gamma irradiation for improvement of NPs’ production was adopted. Under the optimum conditions and after gamma irradiation, the final yields of the respective NPs reached 545.71, 651.67, 463.19, 954.88, 1356.42 mg L−1. To the best of our knowledge, this is the first report on the production and enhancement of different types of nanomaterials from one microbial culture that can open up the way towards the industrialization of the microbial production of nanomaterials.
