Abstract: Reports detection of viable bacteria, cyanobacteria and microalgae in subglacial sediments using epifluorescence microscopy and phospholipid fatty acid (PLFA) analyses. Finds subglacial samples to have higher pH values, coarser texture and lower water content, organic matter, organic carbon, and nitrogen compared with proglacial and supraglacial sediments. Results suggest that subglacial microbial populations can be divided into two groups: autochthonous microorganisms (chemoheterotrophic bacteria) and allochthonous microorganisms retaining ability to proliferate and produce active populations when conditions become favourable.
