The Antarctic continent is largely covered by an expansive ice sheet, but it harbors diverse terrestrial and aquatic habitats in the
coastal ice-free continental margins. Here we present the draft genome of Microbacterium ...

Nesterenkonia sp. strain AN1 was isolated from Antarctic soil and is a polyextremophile, being tolerant of low temperatures,
high salt concentrations, and high alkalinity. Here we report the draft genome sequence of this strain.

BACKGROUND : Post-translational glycosylation of the flagellin protein is relatively common among Gram-negative
bacteria, and has been linked to several phenotypes, including flagellar biosynthesis and motility, biofilm ...

Whether they are exposed to extremes of heat, cold, or buried deep beneath the
Earth‟s surface, microorganisms have an uncanny ability to survive under these
conditions. This ability to survive has fascinated scientists ...

Acetylation is one of the main obstacles to the effective enzymatic conversion of
hemicelluloses to fermentable sugars. In nature, the microbial degradation of hemicellulose
involves the action of deacetylating esterases ...

Welwitschia mirabilis is an ancient and rare plant distributed along the western coast of
Namibia and Angola. Several aspects of Welwitschia biology and ecology have been investigated,
but very little is known about the ...
