TL;DR: A meta-analysis found the activities of seven enzymes to decrease in response to soil contamination with Pb, Zn, Cd, Cu and As, and the much stronger impact of HMs on living microorganisms and their endoenzymes than on extracellular enzymes stabilized on clay minerals and organic matter.

TL;DR: In this paper, the authors determine environmental controls of extracellular enzyme production, and hence on potential enzyme activities (Vmax) and substrate affinities (Km), and conclude that substrate availability for microorganisms mainly determined enzyme activity patterns on the continental scale by the humidity gradient.

TL;DR: A greater stabilization capacity of MF in allophanic soils than in kaolinitic soils due to the amorphous minerals clay materials was confirmed, and an inverse and significant relationship between Al pyrophosphate (Al bound to SOM) and the C-CO2 in volcanic soil, whereas the same correlation did not occur in kaalinitic soil.

TL;DR: In this article, the authors focus on the competition for available carbon in soil, limiting their analyses to the interaction at rhizospheric space, where most processes between microorganisms and mineral phase occurs.

TL;DR: In this paper, the effects of drying and rewetting (D/W) on soil organic matter turnover were evaluated at 5 and 25°C after a 27-day incubation of undisturbed soil cores from a temperate forest.
