Abstract
ANaerobic MEthanotrophic archaea (ANME) archaea play crucial roles in global geochemical cycles and exert significant influence on greenhouse gas emissions. They have coupled the methane cycle with the sulfur cycle, nitrogen cycle, and the metal element cycle by utilizing various electron acceptors such as sulfate, nitrate/nitrite, metal oxides. This review summarizes the potential mechanisms underlying the utilization of different electron acceptors by ANME archaea, encompassing direct interspecies electron transfer, horizontal gene transfer, energy conservation and specialized cellular composition. Additionally, this review also underscores the promising applications of ANME archaea in addressing environmental concerns and sheds light on the burgeoning research imperative. This review aims to furnish a comprehensive understanding of ANME archaea’s capability for utilizing diverse electron acceptors, with the ultimate goal of leveraging this knowledge for methane emission reduction, pollutants removal, electricity and valuable chemicals generation, and other pertinent applications.
期刊介绍：
Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics.
Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges.
The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
