Bacterial Activity in South Pole Snow
ABSTRACT Large populations (200 to 5,000 cells ml −1 in snowmelt) of bacteria were present in surface snow and firn from the south pole sampled in January 1999 and 2000. DNA isolated from this snow yielded ribosomal DNA sequences similar to those of several psychrophilic bacteria and a bacterium whi...
