Chemoautotrophy In Subzero Environments And The Potential For Cold-adapted Rubisco

by Keith Cowing

The act of fixing inorganic carbon into the biosphere is largely facilitated by one enzyme, Rubisco. Beyond well-studied plants and cyanobacteria, many bacteria use Rubisco for chemolithoautotrophy in extreme environments […]

Urea Assimilation and Oxidation Supports the Activity of a Phylogenetically Diverse Microbial Community in the Dark Ocean

by Keith Cowing

Urea is hypothesized to be an important source of nitrogen and chemical energy to microorganisms in the deep sea; however, direct evidence for urea use below the epipelagic ocean is […]
