Název v původním jazyce

Microbial community structure and ecology of subglacial sediments in two polythermal Svalbard glaciers characterized by epifluorescence microscopy and PLFA

Popis výsledku v původním jazyce

Viable bacteria, cyanobacteria and microalgae were detected in subglacial sediment from 2 polythermal glaciers in Svalbard using epifluorescence microscopy and PLFA analyses. The subglacial samples were of higher pH values, coarse texture and low water content, OM, organic carbon , and nitrogen. Bacterial counts of 1.6x107 cells mg OM were found. Cyanobacteria and algae were also of low abundance (4.2 cells mg DW-1). Deglaciated soil were similar to subglacial sediment in physico-chemical properties andmicrobial structure and numbers, unlike soil from vegetated sites or cryoconite. In subglacial and deglaciated soil, relatively low diversity of organisms and low substrate availability was detected by PLFA analyses. Good accordance in microbial community structure assessments between epifluorescence microscopy and PLFA analyses was found. Our results suggest that the subglacial microbial populations can retain the ability to proliferate and give rise to active population when condition
