Composition and thermal properties of membrane lipids in cryptoendolithic lichen microbiota from antarctica.

L Finegold1, M A Singer, T W Federle, J R Vestal.   

Abstract

In Antarctica there exists a cryptoendolithic microbiota which survives extremely low temperatures. Fatty acid analysis of the membrane phospholipids of this microbial community showed a predominance of polyunsaturated fatty acids. Artificial membranes made from the purified community phospholipids remained fluid to below -20 degrees C and had unusual hydration properties.
