Fig. 5From: Metagenomics reveals global-scale contrasts in nitrogen cycling and cyanobacterial light-harvesting mechanisms in glacier cryoconiteHypothesized metabolism of cryoconite bacterial consortia of Polar (Arctic) and High-Mountain Asia (HMA, central Asia) glaciers. Outer light-green and inner brown parts indicate surface oxic layers dominated by Cyanobacteria and inner anaerobic/microaerobic cores of cryoconite granules, respectively. OC: organic compounds; PC: phycocyanin; PE: phycoerythrinBack to article page
