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.

Assaying activity and assessing thermostability of hyperthermophilic enzymes [PDF]

, 2001
There is now a wide variety of intra- and extra-cellular enzymes available from organisms growing above 75°C, and having sufficient stability to allow assay well above this temperature.

Continuous Thermophilic Composting [PDF]

Applied Microbiology, 1962
Under complete mixing conditions, aerobic decomposition of mixed organic waste materials has been maintained continuously in the thermophilic phase in a 55-gal rotating drum. Temperatures ranged between 53 and 70 C. Raw material was added daily or every second day in amounts up to 18 lb per 100 lb of decomposing material. The weight of material removed

Comparative genomics of thermosynechococcaceae and thermostichaceae: insights into codon usage bias

Acta Biochimica Polonica
Members of the families Thermosynechococcaceae and Thermostichaceae are well-known unicellular thermophilic cyanobacteria and a non-thermophilic genus Pseudocalidococcus was newly classified into the former.

Probiotic containing Lactobacillus casei, Lactobacillus bulgaricus, and Streptococcus thermophiles (ACTIMEL) for the prevention of Clostridium difficile associated diarrhoea in the elderly with proximal femur fractures.

Journal of Infection and Public Health, 2018
The incidence of Clostridium difficile associated diarrhoea (CDAD) is greater in elderly patients. Probiotics may have a beneficial effect in the prevention of CDAD.

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.

Viral Diversity Threshold for Adaptive Immunity in Prokaryotes [PDF]

, 2012
Bacteria and archaea face continual onslaughts of rapidly diversifying viruses and plasmids. Many prokaryotes maintain adaptive immune systems known as clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated genes (Cas ...

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 ...
