Decoupling of Growth and Functional Activity in Manganese-Oxidizing Bacteria under High Temperature: A Constraint on Microbial Remediation of Soil Arsenic Contamination

Key Points

This research aims to explore the effects of high temperature on the growth and functional activity of manganese-oxidizing bacteria (MnOB), particularly in relation to arsenic remediation.
Investigated the impact of high temperature on manganese-oxidizing bacteria (MnOB) activity.
Analyzed carbon diversion from the TCA cycle and its effect on NADH supply.
Assessed the implications for microbial remediation of soil arsenic contamination.
High temperature reduces Mn(II)-oxidation activity due to decreased NADH supply.
The study identifies constraints on microbial remediation capabilities under elevated thermal conditions.
Mechanistic insights suggest potential strategies for enhancing MnOB functionality despite temperature challenges.

Abstract

) may divert carbon from the TCA cycle, reducing NADH supply and exacerbating Mn(II)-oxidation loss. This study provides mechanistic insights into the temperature sensitivity of MnOB-mediated arsenic remediation and offers references for functional enhancement under high-temperature conditions.
