Metagenomic Analysis of Antarctic Biocrusts Unveils a Rich Range of Cold-Shock Proteins
Microorganisms inhabiting Antarctic biocrusts develop several strategies to survive extreme environmental conditions such as severe cold and drought. However, the knowledge about adaptations of biocrusts microorganisms are limited. Here, we applied metagenomic sequencing to study biocrusts from east...
