摘要

本研究探讨了 CdS 纳米粒子（NPs）在不同条件下对大肠杆菌生长和新陈代谢的影响。在光照条件下，CdS NPs 显著增强了细菌的生长、葡萄糖同化和生物量积累。关键代谢和应激反应基因的表达增加，表明 ATP 合成和抗氧化应激能力得到改善。此外，CdS NPs 还增强了大肠杆菌的电化学特性，促进了有效的电子传递。在黑暗条件下未观察到明显变化。这些发现表明，光激活的 CdS NPs 通过上调参与生长和氧化应激管理的关键基因，促进了大肠杆菌的生长和代谢效率。

The Influence of Exogenous CdS Nanoparticles on the Growth and Carbon Assimilation Efficiency of Escherichia coli.

This study investigated the impact of CdS nanoparticles (NPs) on Escherichia coli growth and metabolism under varying conditions. Under illumination, CdS NPs significantly enhanced bacterial growth, glucose assimilation, and biomass accumulation. Key metabolic and stress response genes showed increased expression, indicating improved ATP synthesis and oxidative stress resistance. Additionally, CdS NPs enhanced the electrochemical properties of E. coli, promoting efficient electron transfer. No significant changes were observed in the dark. These findings suggest that light-activated CdS NPs promote E. coli growth and metabolic efficiency by upregulating crucial genes involved in growth and oxidative stress management.

期刊介绍： Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
