Seasonal biogeochemical variations in a modern microbialite reef under early Earth-like conditions

The paper studies seasonal changes in a modern microbialite reef, finding that environmental fluctuations drive microbial community shifts and mineralization patterns, indicating metabolic drivers over taxonomy in carbonate precipitation.

Cryptic arsenic cycling controls oxygenic photosynthesis in Precambrian-analog microbial mats

The paper shows cyanobacteria in microbial mats switch from oxygenic to arsenite-driven anoxygenic photosynthesis under high light, revealing a cryptic arsenic redox cycle that may have influenced early Earth oxygenation.

Genomic Insights of an Andean Multi-resistant Soil Actinobacterium of Biotechnological Interest

The paper characterizes the multi-resistant genome of an Andean actinobacterium, revealing its potential for biotechnological applications.

PROTEOMIC SIGNATURES OF MICROBIAL ADAPTATION TO THE HIGHEST UV -IRRADIATION ON EARTH: LESSONS FROM A SOIL ACTINOBACTERIUM

The paper identifies DNA repair and antioxidant mechanisms as key to UV resistance in an Andean soil actinobacterium through proteomic analysis.

Analysis of co-regulated abundance of genes associated with arsenic and phosphate metabolism in Andean Microbial Ecosystems
