Microbial extracellular enzyme activity with simulated climate change

Elementa: Science of the Anthropocene, 2022
It is critical to understand the consequences of environmental change for the microbial regulation of carbon and nutrient cycling. Specifically, understanding microbial community traits, such as extracellular enzyme activity, can help inform nutrient cycling models and address knowledge gaps.

Persistent Activities of Extracellular Enzymes Adsorbed to Soil Minerals [PDF]

Microorganisms, 2020
Adsorption of extracellular enzymes to soil minerals is assumed to protect them against degradation, while modifying their activities at the same time. However, the persistence of the activity of adsorbed enzymes remains poorly understood. Therefore, we studied the persistence of cellulase and α-amylase activities after adsorption to soil amended with ...

Differentiating intracellular from extracellular alkaline phosphatase activity in soil by sonication. [PDF]

PLoS ONE, 2013
Differentiating intracellular from extracellular enzyme activity is important in soil enzymology, but not easy. Here, we report on an adjusted sonication method for the separation of intracellular from extracellular phosphatase activity in soil.

Detection of Extracellular Enzyme Activities inGanoderma neo-japonicum [PDF]

Mycobiology, 2011
The ability of Ganoderma to produce extracellular enzymes, including β-glucosidase, cellulase, avicelase, pectinase, xylanase, protease, amylase, and ligninase was tested in chromogenic media. β-glucosidase showed the highest activity, among the eight tested enzymes.

Contribution of enzymes to soil quality and the evolution of research in Brazil

Revista Brasileira de Ciência do Solo, 2021
Extracellular soil enzymes are fundamental for the functioning of ecosystems. Several processes in the soil depend on the activity of these enzymes, including plant decomposition, soil organic matter formation/mineralization, and nutrient cycling ...

Medicago sativa has Reduced Biomass and Nodulation When Grown with Soil Microbiomes Conditioned to High Phosphorus Inputs

Phytobiomes Journal, 2019
Agricultural over-fertilization may adversely impact plant-microbial interactions affecting crop yield. It is unclear if soil microbiomes respond quickly to changes in fertilizer inputs once conditioned to specific nutrient regimes. We conducted a growth
