When a carbon (C) source is added to a soil volume and causes microorganisms to thrive, a microbial hotspot is formed — a microsite with much higher process rates than the surrounding bulk soil. The formation, size, and lifetime of microbial hotspots in the vicinity of growing roots (rhizosphere) are governed by biotic and abiotic factors. Root exudation stimulates the production of extracellular enzymes and thus soil organic matter (SOM) decomposition. Nonetheless, we lack a mechanistic understanding of the enzymatic response of rhizosphere microorganisms to individual component of the roo...
