Excited to share our new study exploring chemoautotrophy in subzero Arctic brines. We identified cold-adapted Rubisco enzymes in Thiomicrorhabdus species, suggesting unique adaptations for carbon fixation in extreme conditions.

Chemoautotrophy in subzero environments and the potential for cold-adapted Rubisco | Applied and Environmental Microbiology Autotrophy, or the fixation of inorganic carbon to biomass, is a key factor in life’s ability to thrive on Earth. Research on autotrophy has focused on plants and algae, but many bacteria are also aut... https://journals.asm.org/doi/10.1128/aem.00604-25
