A new approach to continuous monitoring of carbon use efficiency and biosynthesis in soil microbes from measurement of CO₂ and O₂ by K. E. Smart, D. O. Breecker, C. B. Blackwood, C. B. Blackwood, C. B. Blackwood, T. M. Gallagher

“…Therefore, understanding processes that control soil carbon stabilization and release is vital to improving our understanding of the global carbon cycle. Heterotrophic respiration is the main pathway by which soil organic carbon is returned to the atmosphere; however, not all carbon utilized by heterotrophs shares this fate, as some portion is retained in the soil as biomass and biosynthesized extracellular compounds. …”
