Abstract

The escalating energy and environmental crises have spurred significant research interest into developing efficient biological remediation technologies for sustainable contaminant and resource conversion. Integrating engineered nano-micro materials (NMMs) with these biocatalytic processes offers a promising approach to improve the microbial performance for environmental remediation. Core to such material-enhanced hybrid biocatalysis systems (MHBSs) is the rational regulation of metabolic processes with the assistance of NMMs, where a fine engineered mass and electron transfer is beneficial for the improved biocatalytic activity. However, the specific mechanisms of those NMMs-enhanced microbial metabolisms are normally overlooked. Here, we review the recent progress in MHBSs, focusing primarily on the mass/electron transfer regulation strategies for an enhanced microbial behavior. Specifically, the NMMs-regulated mass and electron transfer in extracellular, interfacial, and intracellular environment are summarized, where the patterns of diverse microbiological response are discussed thoroughly. Notably, fine modifications of cell interfaces and intracellular compartments by NMMs could even endow the biohybrids with new metabolic functions beyond their natural capabilities. Further, we also emphasize the importance of matching the various metabolic demands of biosystems with the diverse properties of NMMs to achieve efficient environmental remediation through a coordinated regulation strategy. Finally, major challenges and opportunities for the future development and practical implementation of MHBSs for environment remediation practices are given, aiming to provide future system design guidelines for attaining desirable biological behaviors.

纳米微材料调节生物催化新陈代谢,实现高效环境修复:多细胞环境中质量和电子转移的精细工程设计
不断升级的能源和环境危机激发了人们对开发可持续污染物和资源转化的高效生物修复技术的极大研究兴趣。将工程纳米微材料(NMMs)与这些生物催化过程相结合,为改善微生物的环境修复性能提供了一种前景广阔的方法。这种材料增强型混合生物催化系统(MHBSs)的核心是在 NMMs 的协助下合理调节代谢过程,其中精细设计的质量和电子转移有利于提高生物催化活性。然而,NMMs 增强微生物代谢的具体机制通常被忽视。在此,我们回顾了 MHBS 的最新进展,主要侧重于质量/电子传递调控策略,以增强微生物的行为。具体来说,我们总结了 NMMs 在细胞外、界面和细胞内环境中调控的质量和电子传递,并深入探讨了微生物的不同反应模式。值得注意的是,NMMs 对细胞界面和细胞内隔室的精细修饰甚至可以赋予生物杂交体新的代谢功能,超越其天然能力。此外,我们还强调了将生物系统的各种代谢需求与 NMM 的各种特性相匹配的重要性,以便通过协调的调节策略实现高效的环境修复。最后,我们给出了未来开发和实际应用 MHBSs 进行环境修复实践所面临的主要挑战和机遇,旨在为实现理想的生物行为提供未来的系统设计指南。

期刊介绍: Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include: •Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management; •Urban hydrology including sewer systems, stormwater management, and green infrastructure; •Drinking water treatment and distribution; •Potable and non-potable water reuse; •Sanitation, public health, and risk assessment; •Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions; •Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment; •Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution; •Environmental restoration, linked to surface water, groundwater and groundwater remediation; •Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts; •Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle; •Socio-economic, policy, and regulations studies.
