Adaption strategies of extremophiles and the construction of wastewater treatment systems driven by extremophiles.

Unconventional wastewater (such as high-salinity brine, acidic mine drainage, industrial wastewater with extreme temperatures, and highly saline-alkaline wastewater) shares characteristics similar to Earth's extreme environments. Microorganisms in extreme environments rely on unique adaptation mechanisms to drive elemental cycling, providing a new direction for the treatment of unconventional wastewater. This article reviews the tolerance mechanisms of extremophiles in adverse environments and expounds on the correlation between the tolerance mechanism and the potential requirements for wastewater treatment.

Self-Trapped Excitons or Bi Ions for Broad Emission in a Lead-Free Double Perovskite? Hearing What Pressure Says.

The broad emission origin of lead-free double perovskites with ns-metal ion doping remains a long-standing controversy. Herein, pressure is introduced as a robust tool to determine the mechanism of broad emission from CsAgInBiCl nanocrystals (NCs). The negative correlation between the crystal field strength and broad emission wavelength under compression corroborates that the broad emission is indeed attributed to the radiative recombination of self-trapped excitons, ruling out Bi emission from P ( = 0, 1, or 2) to S as an alternative mechanism.

GmFER1, a soybean ferritin, enhances tolerance to salt stress and root rot disease and improves soybean yield.

The plant stress response mechanism is activated by biotic and abiotic stresses, but its continuous activation typically affects growth. The role of ferritin in regulating biomass accumulation has been extensively characterized in diverse plant species; however, the underlying mechanisms through which it contributes to salt stress tolerance and Fusarium resistance remain poorly understood. Here, we confirm that overexpression of ferritin leads to iron accumulation and Fe sequestration in both aboveground and roots, activating the iron uptake and transport system.
