Clarification of microbial community structures around Antarctic lakes

15 May 2020


A research group of Assistant Prof. Yuu Hirose of the Department of Applied Chemistry and Life Science at Toyohashi University of Technology, Niigata University, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and the National Institute of Polar Research, has revealed the community structure of microorganisms living around freshwater lakes in the Langhovde and Skarvsnes ice-free areas of Antarctica. An analysis of samples collected from lake shores, puddles, etc. using a next-generation sequencer has verified that cyanobacteria and tardigrades are widely distributed and specific eukaryotic algae are dominant in certain sites. This knowledge will contribute to clarification of adaptation mechanisms of microorganisms to severe physical stresses in Antarctica, e.g. low temperatures, ultraviolet irradiation and freeze-thaw cycles.
