Microbial carbon use efficiency (CUE) measures the fraction of assimilated carbon allocated to growth versus respiration—typically ranging from 0.3 to 0.6 in temperate soils.
High-CUE microbes convert more plant-derived carbon into stable necromass and extracellular polymers, enhancing soil organic carbon persistence.
