“…It also exhibits some of the fastest growing tufas in the world (Medina Ferrer et al, 2022; Rosen et al, 2004), that is, stromatolite‐like structures hypothesised to emerge from a combination of abiotic and microbial processes (Cousin & Stackebrandt, 2010; Ford & Pedley, 1996), and constituting promising targets for recovering historical biosignatures (Hays et al, 2017; Potter‐McIntyre et al, 2016; Westall et al, 2021). These features make BSL a fascinating system for studying the boundaries of life's adaptations, for understanding life on early Earth and potentially on other planets, for recovering novel deeply rooted taxa, and for discovering biotechnologically useful strains and enzymes (Horikoshi, 1999; Jeilu, Simachew, et al, 2022; Mohamed et al, 2023). LSL constitutes an interesting but much less studied comparison to BSL: Despite its spatial proximity to BSL and their shared geological history, LSL does not exhibit a strong halo‐ or chemocline, likely due to its smaller depth (about 12 m in the centre).…”

Big Soda Lake, Nevada, is a multi‐extreme meromictic lake, whose hypersaline hyperalkaline bottom waters feature permanent anoxia and high concentrations of arsenic, sulphide and ammonia. These properties make Big Soda Lake—and the adjacent Little Soda Lake—a fascinating system for exploring life's boundaries, discovering novel microbial taxa and identifying biotechnologically useful strains. To date, the taxonomic diversity and metabolic capabilities of microorganisms in this system remain largely unknown. Here, we fill this gap using microbiome surveys across the Big and Little Soda Lake water columns, including 16S rRNA sequencing, fungal ITS2 sequencing and gene‐ and genome‐resolved metagenomics. We accompany these surveys with measurements of salinity, pH, temperature, oxygen, ammonium and ammonia concentrations. Our analyses reveal rich bacterial communities, taxonomically and functionally differentiated along Big Soda Lake's oxycline and, to lesser extent, between lakes. Fungal communities were dominated by a small number of families, while nearly no archaea were detected. Pathways related to perchlorate reduction, anoxygenic phototrophy, fermentation, dissimilatory metabolism of arsenite/arsenate, sulphur compounds, nitrogen compounds and hydrogen, were particularly prevalent. A total of 129 high‐quality bacterial and archaeal metagenome‐assembled genomes (completeness ≥ 80%, contamination ≤ 5%) were recovered, yielding insight into the taxonomic distribution of microbial metabolic pathways.

“…Hence, the treatment of HCHO has attracted much attention. There are many traditional methods for HCHO treatment, such as adsorption purification method [6][7][8][9][10], biological degradation method [11][12][13], air negative ion technology [14][15][16], and thermal destruction method [17][18][19]. However, these methods all have certain deficiencies for poor HCHO treatment effect and easily-triggered secondary pollution.…”

Formaldehyde (HCHO), an indoor volatile organic compound, is seriously harmful to human health. Therefore, green and effective decomposition of HCHO is essential. TiO2 has been employed for the degradation of HCHO via photocatalytic generation of reactive oxygen species (ROS) (O2-, ·OH), yet the low specific surface area of crystalline TiO2 depressed the catalytic performance. Herein, we prepared TiO2 aerogels with high specific surface area and high porosity by sol-gel method, and added PVA to introduce flexible molecular chains for pore size regulation. The photocatalytic performance test verifies that the pore size of TiO2 aerogel is one of the important factors for HCHO decomposition. Notably, through the establishment of theoretical model and calculation, we validated that the efficiency of HCHO decomposition is related to the oxygen pressure in the pores of TiO2 aerogel, and the oxygen pressure is inversely proportional to the pore size. Accordingly, the optimal pore size of TiO2 aerogel for the photocatalytic HCHO decomposition is 2 nm~10 nm. This study provides a theoretical idea for TiO2 aerogels in the decomposition reaction of HCHO, which is expected to inspire more breakthroughs in the study of TiO2 aerogels for green chemistry.
