Environmental Controls on Crenarchaeol Distributions in Hydrothermal Springs

Environmental Microbiology, Volume 28, Issue 2, February 2026.
The optimal pH and temperature for crenarchaeol (a unique archaeal lipid) production in hydrothermal springs are 7.4°C and 46°C, respectively, which has important implications for archaeal evolution. Our study also indicates that pH is the most important environmental variable for archaeal lipid membrane compositions.

Engineered Leaf‐Branch Compost Cutinase with Enhanced PET Degradation Across a Broad Temperature Range

ChemSusChem, Volume 19, Issue 1, January 2026.
This study aimed to identify poly(ethylene terephthalate) (PET)‐degrading enzymes effective under industrially relevant conditions. An engineered leaf and branch compost cutinase variant showed enhanced PET hydrolysis across multiple temperatures, outperforming existing enzymes.

Toward the Bioremediation of Nylon Waste Materials: Genome Mining Leads to the Identification of a Thermostable Laurolactamase From Thermopolyspora flexuosa

ChemSusChem, Volume 19, Issue 1, January 2026.
To enhance nylon waste remediation, genome mining was used to identify a thermostable laurolactam hydrolase from Thermopolyspora flexuosa with activity against an important cyclic nylon derivative. Substrate scope analysis and structural modeling revealed key features controlling enzyme‐substrate compatibility, providing a promising foundation for ...

Key role of hydrogen in regulating hydrogenases and the reductive TCA cycle in a thermophilic, autotrophic sulfur-reducing bacterium

Applied and Environmental Microbiology
Many thermophilic autotrophs in deep-sea hydrothermal vents are anaerobes that require H2 for growth. However, our understanding of how non-methanogenic thermophilic hydrogenotrophs adapt to low H2 conditions is nascent.

Optimizing the Coagulation Potential of Pineapple (Ananas comosus) Extract for Chickpea Cheese Production

Food Science &Nutrition, Volume 14, Issue 1, January 2026.
This study developed and optimized chickpea‐based cheese using pineapple (Ananas comosus) extract as a natural coagulant. The optimized formulation improved yield, texture, protein content, mineral composition, and sensory acceptability compared to control cheese.
