In studying the basal respiration, microbial biomass (substrate-induced respiration, SIR), and metabolic quotient (qCO2) in western red cedar (Thuja plicata Donn ex D. Don)-western hemlock [(Tsuga heterophylla Raf.) Sarg.] ecosystems (old-growth forests, 3- and 10-year-old plantations) on northern Vancouver Island, British Columbia, Canada, we ...

Environmental Pollution, 2018
Efficiency and the preservation of soil functions are key requirements for sustainable remediation of contaminated soil. Microbial decomposition and conversion of substrates is a fundamental soil function. Pilot-scale EDTA-based soil washing recycled chelant generated no wastewater and removed 78% of Pb from acidic farmland soil with 860 mg kg-1 Pb and

The content of microbial biomass (MB) was determined in samples of gray forest, chestnut, and tundra soils with different physicochemical properties (0.4-22.7% Corg; 8.4-26.8% silt particles; pH 4.3-8.4) by the methods of substrate-induced respiration (MB(SIR)) and direct microscopy (MB(M)).

Translationally active soil microorganisms during substrate-induced respiration
2023ABSTRACT Soil microorganisms carry out many processes that are fundamental to soil functions. Among the millions of microbial cells present in a gram of soil, however, less than 2% are commonly estimated to be active at any point in time.

Abstract Soil heterotrophic respiration and its temperature sensitivity are affected by various climatic and environmental factors. However, little is known about the combined effects of concurrent climatic and environmental changes, such as climatic warming, changing precipitation regimes, and increasing nitrogen (N) deposition.

The relationship between substrate-induced respiration and swelling in Azotobacter vinelandii
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract 1. 1. When oxidizable substrates are added to a starved suspension of Azotobacter vinelandii osmotically shrunken in 0.2 M KCl, a decrease in absorbance is observed which results from a change in light scattering as the cells increase in volume. 2. 2.

Measuring bacterial and fungal substrate-induced respiration in dry soils
Soil Biology and Biochemistry, 1996Abstract The substrate-induced respiration inhibition (SIRIN) method of Anderson and Domsch for partitioning bacterial and fungal contributions to soil respiration was modified for application to dry soils. This new method also provided a comparative basis when measuring SIRIN in soils of different moisture contents.

Estimating crop residue decomposition coefficients using substrate-induced respiration
Soil Biology and Biochemistry, 1997Abstract Modeling of crop residue decomposition for nutrient cycling and effectiveness of residues to control soil erosion requires information on crop-specific decomposition coefficients (k). Respiration of decomposing residues reflects the activity of the microbial community and should give an indication of the residue decomposition rate.

Substrate induced respiration in soil amended with different amino acid isomers
Applied Soil Ecology, 1994Abstract The substrate induced respiration (SIR) by the soil microbial community was determined using glucose, l -alanine, d -alanine, l -glutamine and d -glutamine as the substrate in order to compare the utilization of l - and d -isomers of alanine and glutamine by the microbial community in a podzolic soil.

Determination of the soil microbial biomass carbon using the method of substrate-induced respiration
Eurasian Soil Science, 2011Specific features of determining the carbon content in the soil microbial biomass using the method of substrate-induced respiration (MBSIR) were studied as related to the conditions of the incubation (the glucose concentration and temperature) and pre-incubation (the duration and temperature) of the soil samples collected in the summer (tundra gley and
