RNA Polymerase-Binding and Transcription Initiation Sites Upstream of the Methyl Reductase Operon of Methanococcus vannielii [PDF]
, 1988 RNA Polymerase, purified from Methanococcus vannielii, was shown by exonuclease III footprinting to bind to a 49-base-pair (bp) region of DNA in the intergenic region upstream of mcrB.

ChemBioChem, Volume 26, Issue 12, June 16, 2025.Targeted genome mining identified thermostable enzymes (PETases) that hydrolyze the commonly used plastic polymer polyethylene terephthalate (PET). Thermostable enzymes are identified from thermophilic microbial sources. Experimental results reveal enzymatic activity on authentic PET films, highlighting potential for industrial application.

Did silicon aid in the establishment of the first bacterium? [PDF]
, 2003 Silicic acid increased numbers of both aerobic and facultatively anaerobic bacteria in ultrapure water incubated under strict oligotrophic conditions; soil extracts acted as the bacterial inoculum. The results are discussed in relation to the possibility

Mesophilic and thermophilic methane fermentation of Euphorbia tirucallis [PDF]
, 1989 La méthanisation d'#Euphorbia tirucalli$ a été réalisée en conditions mésophile et modérément thermophile. Trois différents pré-traitements de cette plante ont été testés : simple fragmentation, broyat, séchage puis broyage.

The Process and Pathogen Behavior in Composting: A Review [PDF]
arXiv, 2014 Composting is defined as the biological decomposition and stabilization of organic substrates under aerobic conditions to allow the development of thermophilic temperatures. This thermophilic temperature is a result of biologically produced heat. Composting produces the final product which is sufficiently stable for storage and application to land ...

Entropic stabilization of proteins and its proteomic consequences [PDF]
, 2005 We report here a new entropic mechanism of protein thermostability due to residual dynamics of rotamer isomerization in native state. All-atom simulations show that Lysines have much greater number of accessible rotamers than Arginines in folded states of proteins.
