与单一的微生物菌株相比，由各种微生物组成的微生物聚生体之间的复杂相互作用已被证明在扩展生态功能和完成生物过程方面是有效的。电活性微生物和可降解微生物在生物能源的生产和对人体有害的有机污染物的降解中起着重要作用。这些微生物可以与其他微生物强烈相互作用，促进代谢合作，从而促进发电和污染物降解。本文根据EM和DMs对不同环境的适应能力，对EM和DMs的几种具体类型进行了描述，并对EM在细胞外电子传递中的作用机制进行了综述。EM和DM之间的相互作用的影响进行了评估，在电力生产和降解效率。介绍了微生物菌群强化的原理，如生物量的提高、降解途径的改变、生物催化潜力的提高等，这些都直接或间接地有益于人类健康。环境微生物是解决环境污染和能源危机的关键。各种微生物的组合有利于利用各自的优点。系统阐述了电活性微生物和可降解微生物的特性及其相互作用。首先分析了微生物联合体的产电、产氢和污染物去除能力的增强。呼吁对功能化微生物和微生物联合体进行研究。
Compared to single microbial strains, complex interactions between microbial consortia composed of various microorganisms have been shown to be effective in expanding ecological functions and accomplishing biological processes. Electroactive microorganisms (EMs) and degradable microorganisms (DMs) play vital roles in bioenergy production and the degradation of organic pollutants hazardous to human health. These microorganisms can strongly interact with other microorganisms and promote metabolic cooperation, thus facilitating electricity production and pollutant degradation. In this review, we describe several specific types of EMs and DMs based on their ability to adapt to different environments, and summarize the mechanism of EMs in extracellular electron transfer. The effects of interactions between EMs and DMs are evaluated in terms of electricity production and degradation efficiency. The principle of the enhancement in microbial consortia is also introduced, such as improved biomass, changed degradation pathways, and biocatalytic potentials, which are directly or indirectly conducive to human health. Environmental microorganisms are essential in solving pollution and energy crisis. The combination of various microorganisms facilitates the utilization of respective advantages. The characteristics of electroactive microorganisms and degradable microorganisms and their interactions are elucidated systematically. The enhancement of electricity production, hydrogen production, and pollutant removal capacity in microbial consortia was first analyzed. Call for research on functionalized microorganisms and microbial consortia.
