Summary: Many Archaea produce membrane-spanning lipids that enable life in extreme environments. These lipids contain multiple ring structures, the degree of which is associated with the acidity, temperature, and energy limitation of the environment. Researchers have recently identified genes related to ring structure synthesis in the genomes of two Sulfolobaceae. However, the distribution and abundance of these genes in different environments inhabited by Archaea are still unknown. In this study, the researchers examined the distribution of these genes in relation to environmental temperature and pH, and found a strong negative correlation between gene abundance and pH, and a weak positive correlation between gene abundance and temperature. They also discovered these genes in various classes of Archaea. These findings highlight the important role of gene-regulated lipid cyclization in the diversification of Archaea in hot and acidic environments.

Summary: Hot springs are a significant source of arsenic release into the environment. Methylated thioarsenates, a group with high mobility and toxicity, contribute up to 13% of the total arsenic in hot spring samples from the Tengchong volcanic region in China. Methanogens, especially Methanosarcina, were found to be responsible for arsenic methylation, suggesting a combination of biotic arsenic methylation and arsenic thiolation in sulfide-rich hot spring environments.

Summary: The Dong-Xi-Taijinaier Salt Lake (DXTSL) in the Qaidam Basin is a significant lithium reserve in China, but the origin of the lithium deposits in this region is still unknown. The study investigated the hydrochemistry and lithium isotopes of water and solid samples from the Nalenggele River catchment, along with rock leaching experiments. The results showed that hot springs in the upstream had high lithium content but low 87Li values, indicating them as an important lithium source. Additionally, leaching experiments revealed that volcanic rock weathering and hot springs are the main contributors to the lithium deposits in DXTSL.

Summary: The air oxidation rate of Cr1-x Fe x (OH)(3) in dark and alkaline environments is influenced by pH, the Fe/Cr ratio, and the presence of siderophores. The role of oxygen in the dark and the effects of organic ligands on Cr(III) oxidation are often overlooked. This study investigates the kinetics of Cr1-x Fe x (OH)(3) oxidation by oxygen in the dark, considering pH, Fe/Cr ratio, and the presence of siderophores. Results show that pH and Fe/Cr ratio linearly affect the Cr(III) oxidation rate, while the siderophore promotes the formation of soluble organically complexed Cr(III) and enhances its oxidation by oxygen. This study emphasizes the importance of oxygen and its interaction with siderophores in the oxidation of Cr(III)-Fe(III) hydroxides.
