Flavobacteriaceae bacterium 3519-10

Flavobacteriaceae bacterium (strain 3519-10) was isolated from glacial ice at a depth of 3519 m, just above the accreted ice from Subglacial Lake Vostok, the largest subglacial lake in Antarctica. Ice at this depth is near the bottom of a layer of deformed glacial ice and is more than 420,000 years old. It is less than 20 m above the layer of accretion ice originating from Subglacial Lake Vostok and has a temperature of approximately -8 degrees Celsius. This bacterium produces a 54 kDa ice-binding protein that is similar to ice-binding proteins previously found in sea ice diatoms, a snow mold, and a sea ice bacterium. The protein has the ability to inhibit the recrystallization of ice, a phenotype that has clear advantages for survival in ice (adapted from PMID 18622572). (EBI Integr8)
