Evidence of molecular adaptation to extreme environments and applicability to space environments [PDF]
, 2008 This is initial study of a gene signatures responsible for adapting microscopic life to the life in extreme Earth environments. We present a results on ID of the clusters of COGs common to several hyperthermophiles and exclusion of those common to a mesophile: E.coli.K12, will yield a group of proteins possibly involved in adaptation to life under ...

The Resilience of Life to Astrophysical Events [PDF]
Scientific Reports 7 (2017) 5419, 2017 Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself. Here we instead explore the statistics of events that completely sterilise an Earth-like planet with planet radii in the range $0.5-1.5 R_{Earth}$ and temperatures of $\

Pressure and temperature dependence of growth and morphology of Escherichia coli: Experiments and Stochastic Model [PDF]
, 2012 We have investigated the growth of Escherichia coli E.coli, a mesophilic bacterium, as a function of pressure $P$ and temperature $T$. E.coli can grow and divide in a wide range of pressure (1-400atm) and temperature ($23-40^{\circ}$C). For $T>30^{\circ}$

ChemBioChem, EarlyView.This analysis reveals structural heterogeneity in the lipopolysaccharide lipid A from the cold‐adapted Gram‐negative bacterium Polaribacter sp. SM1127, with variations in fatty acid chain number, length, branching, saturation, and hydroxylation degree, likely aiding bacterial adaptation to cold environmental stressors. Lipopolysaccharide is shown to be

Extremophiles in an Antarctic Marine Ecosystem [PDF]
Microorganisms, 2016 Recent attempts to explore marine microbial diversity and the global marine microbiome have indicated a large proportion of previously unknown diversity. However, sequencing alone does not tell the whole story, as it relies heavily upon information that is already contained within sequence databases.

Extremophiles and biotechnology: current uses and prospects [version 1; referees: 2 approved]
F1000Research, 2016 Biotechnology has almost unlimited potential to change our lives in very exciting ways. Many of the chemical reactions that produce these products can be fully optimized by performing them at extremes of temperature, pressure, salinity, and pH for ...

Genomic and proteomic evidences unravel the UV-resistome of the poly-extremophile Acinetobacter sp. Ver3 [PDF]
, 2015 Ultraviolet radiation can damage biomolecules, with detrimental or even lethal effects for life. Even though lower wavelengths are filtered by the ozone layer, a significant amount of harmful UV-B and UV-A radiation reach Earth?s surface, particularly in

Polyhydroxyalkanoates (PHA) toward cost competitiveness and functionality
Advanced Industrial and Engineering Polymer Research, 2020 Polyhydroxyalkanoates (PHA) have been produced by several bacteria as bioplastics in industrial scales. PHA commercialization has been challenging due to its complexity and the associated high cost together with instabilities on molecular weights (Mw ...
