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 ...

Effects of Mixing Feldspathic Sandstone and Sand on Soil Microbial Biomass and Extracellular Enzyme Activities—A Case Study in Mu Us Sandy Land in China

Applied Sciences, 2019
Microbial biomass, extracellular enzyme activity, and their stoichiometry in soil play an important role in ecosystem dynamics and functioning. To better understand the improvement of sand soil quality and the limitation of soil nutrients after adding ...

Differences of soil enzyme activities and its influencing factors under different flooding conditions in Ili Valley, Xinjiang [PDF]

PeerJ, 2020
Background A wetland is a special ecosystem formed by the interaction of land and water. The moisture content variation will greatly affect the function and structure of the wetland internal system.

Effects of metribuzin on the activity of some enzymes in soil

Pesticidi i fitomedicina, 2008
Effects of metribuzin on the activity of some enzymes in soil was investigated. Trials were set up in the laboratory on a clay loam soil. Metribuzin was applied at 12.0, 24.0 and 60.0 mg/kg soil rates and soil samples were collected 3, 7, 15, 30 and 45 days after metribuzin treatment for analyses.

Microbial volatile fingerprints: potential use for soil/water diagnostics and correlation with traditional microbial parameters [PDF]

, 2007
This project used an electronic nose (E-nose) system composed of an array of 14 nonspecific conducting polymer sensors for soil and water diagnostics, based on qualitative microbial volatile production patterns. It tested the feasibility of using soil

The relationship between soil properties, enzyme activity and land use

Leśne Prace Badawcze, 2017
The aim of this study was to assess the effects of different types of land use (forest, tillage and pasture) on soil properties, especially enzyme activity. Our investigation was carried out on 53 research plots with 11 plots in broadleaved forest stands,

Localization of C Cycle Enzymes in Arable and Forest Phaeozems within Levels of Soil Microstructure

Microorganisms, 2023
Soil microbial and enzyme activities are closely related to the spatial variability of soil environmental conditions at the microscale (μm-mm). The origin and localization of the enzymes are somewhat neglected when the measured activity is used to ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Soil-specific enzyme activity provides novel insight into the soil microbial necromass accumulation during sand dune fixation

Frontiers in Microbiology
IntroductionSoil enzymes are critical to plant growth and soil carbon turnover. However, the traditional method of assessing enzyme activity per unit of soil may be insufficient; instead, soil-specific enzyme activity per unit of soil organic carbon ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
